Superman is a 2025 American superhero film inspired by the iconic DC Comics character of the same name. Written and directed by James Gunn, it serves as the inaugural entry in the DC Universe (DCU) produced by DC Studios and marks the second reboot of the Superman film franchise.
David Corenswet stars as Clark Kent / Superman, joined by a stellar cast that includes Rachel Brosnahan, Nicholas Hoult, Edi Gathegi, Anthony Carrigan, Nathan Fillion, and Isabela Merced. The story follows Clark Kent as he grapples with the challenge of reconciling his Kryptonian origins with the life and values he’s known growing up with his adoptive human family in Smallville, Kansas.
"'How can you take a character like this, who's perceived as old-fashioned by many? There have been so many different permutations of the character throughout the years, so how could you do it for a modern audience?' I knew what I wanted to do in creating a story that was both utterly human and utterly fantastic... It [has] all the fantastic elements that we've never really seen in a Superman movie: the flying dog, the giant Kaiju, pocket universes, science and sorcery, and all these things that were in the old Max Fleischer cartoons."
- James Gunn on Superman (Total Film, April 2025)
James Gunn’s Superman is set to redefine the legacy of the Man of Steel for a new era. As DC Studios kicks off its cinematic reboot, all eyes are on how this iconic character will be reinterpreted under Gunn’s direction. From casting choices and creative shifts to deep-cut comic influences and production secrets, there’s more to this film than just a red cape and an “S” on the chest. Here are the most intriguing facts you may not know about Superman (2025) - and why this version might just take flight in a way we’ve never seen before.
Superman Is The First Film In The DCU
Written and directed by James Gunn, Superman marks the first installment in the newly launched DC Universe (DCU) under DC Studios and stands as the second reboot of the Superman film franchise. David Corenswet takes on the role of Clark Kent / Superman, joined by a talented ensemble cast including Rachel Brosnahan, Nicholas Hoult, Edi Gathegi, Anthony Carrigan, Nathan Fillion, and Isabela Merced. The film explores Superman’s deeply personal journey as he strives to reconcile his alien Kryptonian heritage with the life he’s built alongside his adoptive human family.
It is the first film of the DCU's Chapter One: Gods and Monsters.
Superman Was Meant To Be Henry Cavill
Development on a sequel to Man of Steel (2013), part of the DC Extended Universe (DCEU), began as early as October 2014, with Henry Cavill expected to return as Superman. However, following the troubled production of Justice League (2017), plans for the sequel gradually unraveled and by May 2020, the project was no longer moving forward. In August 2022, James Gunn began developing a new Superman film. Just a few months later, in October, Gunn was named co-CEO of DC Studios alongside producer Peter Safran, and the two set out to build a brand-new DC Universe. By December, it was confirmed that Gunn himself was writing the new Superman film.
The Man Of Steel Sequel Was Canned After Justice League (2017)
Man of Steel director Zack Snyder revealed that early discussions for a sequel included bringing back the imprisoned Kryptonians from the first film, as well as introducing the iconic villain Brainiac. By August 2016, the sequel was in active development and considered a top priority at the studio - a status confirmed the following month by Henry Cavill's manager, Dany Garcia. Amy Adams, who played Lois Lane, shared in November that work on the screenplay was underway.
By March 2017, director Matthew Vaughn had emerged as Warner Bros.’ top choice to helm the project and had entered preliminary talks. Interestingly, Vaughn - along with comic book writer Mark Millar - had previously pitched a separate Superman trilogy before Man of Steel was developed. Their version reimagined Krypton’s destruction as happening only after Superman had already grown up on the planet.
However, after the troubled production of Justice League (2017), Warner Bros. began rethinking its strategy for DC films. By the end of that year, hopes for a Man of Steel sequel had significantly cooled, with insiders saying it wasn’t coming "anytime soon, if at all." Producer Charles Roven confirmed that while story ideas were discussed, no script had ever been written.
Originally Called Superman: Legacy
The film was officially titled Superman: Legacy the following month, with James Gunn confirmed as director by March 2023. In June, David Corenswet and Rachel Brosnahan were cast in the lead roles. By the end of February 2024, the subtitle "Legacy" was dropped, and principal photography kicked off in the striking landscapes of Svalbard, Norway.
Filming Locations Included Svalbard, Norway
Filming officially began in Svalbard, Norway, with the production spending a week in the stunning Adventdalen valley to capture scenes set at the iconic Fortress of Solitude. Director James Gunn selected Svalbard for its breathtaking natural beauty and its Arctic-like landscapes, which closely mirror the Fortress’s traditional setting. While those scenes brought a remote, icy atmosphere to life, the bulk of production took place at Trilith Studios in Atlanta, Georgia, with additional location shoots around Georgia and Ohio.
Inspired by All-Star Superman (2005)
The film draws inspiration from several iconic comic storylines, most notably All-Star Superman (2005–2008) by Grant Morrison and Frank Quitely. James Gunn specifically cited All-Star Superman as a key influence on Superman: Legacy, and just one day after his announcement, the celebrated comic surged to the top of Amazon’s best-selling comic book list.
This Superman Is 25 Years Old
According to director James Gunn, Corenswet’s Superman is portrayed as being around 25 years old - positioning him as a more seasoned hero than Tom Welling’s young Clark Kent from Smallville (2001–2011), yet still younger than Henry Cavill’s take on the character in the DC Extended Universe (DCEU).
Superman Embodies “the American Way”
Producer Peter Safran described this new take on Superman for the DC Universe as "the embodiment of truth, justice, and the American way" - a symbol of kindness in a world that often sees kindness as old-fashioned.
Superman Is In Love With Lois Lane and Has Superhero Friends
James Gunn explains that in the film, Clark is finding success both as a journalist and as Superman, but new challenges throw his world off balance. He’s "madly in love" with his colleague Lois Lane and begins forging friendships with other superheroes who see him as somewhat naive. These experiences test Clark’s values and decisions, revealing his flaws and setting him on a deeply personal journey of growth and self-discovery.
David Corenswet Took Inspiration From Christopher Reeve
Corenswet differentiated the role between Clark's interactions with his parents, his job at the Daily Planet, and as Superman. He described Superman as a "public facing character" who wants to present himself as calm but with authority. Corenswet drew inspiration for Clark from the comic book All-Star Superman (2005–2008) by Grant Morrison and Frank Quitely and the posture of Christopher Reeve's portrayal from the 1978–87 Superman film series.
Superman Is The “Quietest Most Wonderful Man”
Corenswet also found inspiration for Clark’s voice and demeanor in his brother-in-law - a man he described as the “quietest, most wonderful” despite standing an imposing 6 feet 8 inches tall and weighing 270 pounds. Similarly, Clark is portrayed as a “big presence” who’s simultaneously “desperately trying to be as small and as quiet as possible,” capturing that subtle tension between strength and humility.
Superman Uses “Hypnotic Glasses”
James Gunn collaborated with DC Comics writer Tom King to explore how other characters accept Clark’s secret identity. They revived the idea of Superman’s iconic hypnotic glasses, which subtly alter his appearance and help maintain the “suspension of disbelief.” Gunn brought this detail back into the film, noting that it had “kind of been forgotten” in recent comic book adaptations.
Rachel Brosnahan Met Several Journalists Before Taking On Lois Lane
Rachel Brosnahan described Lois Lane as "fiercely intelligent" and full of fire. To bring a fresh, modern edge to the iconic reporter, she consulted with several real-life journalists - offering a new take that contrasts with Lois’s earlier comic book versions and past on-screen portrayals.
Nicholas Hoult Wanted Lex Luthor To Be A Real Threat
Nicholas Hoult plays the CEO of LuthorCorp and Superman’s arch-nemesis - a man who resents Superman’s immense power, especially because it clashes with his own beliefs. Hoult describes Luthor as obsessive, determined, and relentless, aiming to make him feel like a truly credible threat. Driven by a complex mix of emotions, including a desperate need to be acknowledged for his scientific genius, Luthor stops at nothing to achieve his goals.
Super... man... he's not a man. He's an it, that's somehow become the focal point of the entire world's conversation. I will not... accept that.” - Lex Luthor
Nicholas Hoult Was Inspired By Michael Rosenbaum In Smallville
Nicholas Hoult drew inspiration from Michael Rosenbaum’s iconic Lex Luthor in Smallville and looked to billionaire Steve Jobs for influence on Luthor’s sleek uniform design. To embody the role fully, Hoult also committed to working out, taking cues from the powerful depiction of Luthor in All-Star Superman.
Nicholas Hoult’s Son Shaved His Head For The Role
In a memorable moment, Nicholas Hoult’s son Joaquin helped prepare him for the role by shaving his head. Director James Gunn drew inspiration for Luthor’s character from Brian Azzarello’s limited series Lex Luthor: Man of Steel (2005), as well as the “reckless scientific genius” portrayal of Luthor created by Jerry Siegel in the comic books of the 1950s and ’60s.
Mister Terrific Is An “Atheist who believes in Justice”
Edi Gathegi takes on the role of Michael Holt, aka Mr. Terrific - a brilliant superhero and inventor who uses cutting-edge gadgets to fight crime. As a member of the Justice Gang, sponsored by Maxwell Lord, Mr. Terrific is defined by his sharp intellect and unwavering commitment to justice. Gathegi described his character as an "atheist who believes in justice," shaped by the profound loss of his wife, which led him to find purpose in knowledge. Known for holding an astonishing 14 PhDs and expertise across fields like physics and engineering, Mr. Terrific relies on his signature T-Spheres - floating, multifunctional devices - for combat, analysis, and hacking. Echo Kellum previously portrayed a version of the character, Curtis Holt, on CW’s Arrow (2012).
Anthony Carrigan Bought His Personal Experience With Alopecia To Metamorpho
Anthony Carrigan plays an archaeologist-turned-superhero who has the extraordinary power to transmute elements within his own body into various forms. As a member of the Justice Gang, his character brings a unique set of abilities to the team. Carrigan found it refreshing to step into the shoes of a hero after previously portraying the Batman villain Victor Zsasz on Gotham (2014–2019). Drawing from his own experience with alopecia, he aimed to bring “authenticity and truth” to the role by connecting with Metamorpho’s struggles over his powers and identity.
Nathan Fillion Was Inspired By The Golden Girls For Green Lantern
Nathan Fillion brings to life Guy Gardner, an abrasive galactic peacekeeper of the Green Lantern Corps and member of the Justice Gang. Fillion describes Gardner as a fearless, overconfident jerk with no filter. To capture that blunt, outspoken personality, he drew inspiration from Estelle Getty’s iconic role as Sophia Petrillo on The Golden Girls (1985–1992). Fillion also pointed to Gardner’s origin story - where a bus accident left him in a coma - as the moment that “flipped the switch,” giving the character his uniquely offbeat edge.
Nathan Fillion Insisted On Guy Gardener’s Bowl Cut
The film proudly keeps Guy Gardner’s iconic bowl-cut hairstyle straight from the comics - something Nathan Fillion was passionate about preserving, even amid discussions about updating his look.
Isabela Merced Didn’t Tell DC About Her Role In Madame Web
Isabela Merced stars as a fierce superhero with wings and an arsenal of melee weapons, a key member of the Justice Gang. Reincarnated from an alien being, her character carries memories and past trauma, which show through her grumpy demeanor. Merced found that the film’s blend of self-awareness and humor helped her “make light of [her] trauma.” Standing at just 5 feet 1 inch (1.55 meters), her stature sets her apart from other heroes in the DC Universe. Interestingly, Merced felt that playing Anya Corazón in Sony’s Spider-Man Universe film Madame Web (2024) helped prepare her for the role of Hawkgirl - though she kept that connection under wraps from the Superman filmmakers, just in case they preferred she not play both roles.
Jonathan and Martha Kent May Speak Like Richard Christy
Pruitt Taylor Vince and Neva Howell bring to life Jonathan and Martha Kent, Clark’s adoptive human parents. To perfect their Kansan accents, both actors studied recordings of Richard Christy - drummer for Charred Walls of the Damned and a longtime personality on The Howard Stern Show - to capture the authentic regional tone needed for their roles.
Wendell Pierce Really Wants To “Get” Luthor
Wendell Pierce steps into the role of Perry White, the gruff editor-in-chief of the Daily Planet. Pierce explains that White’s usual grumpiness stems from a deeply personal betrayal - Luthor had an affair with White’s wife, and there’s even speculation that White’s second child might actually be Luthor’s. This betrayal fuels White’s relentless drive throughout the film, as he’s determined to “get to” Luthor. Since Pierce didn’t grow up reading comic books, he turned to friends for insights to bring authenticity to the character.
Frank Grillo Stars As Rick Flag Sr
Frank Grillo reprises his role as A.R.G.U.S. director Rick Flag Sr. from the animated DCU series Creature Commandos (2024–present).
Sean Gunn, James Gunn’s Brother Is Maxwell Lord
James Gunn’s brother, Sean Gunn, takes on the role of Maxwell Lord, the tech billionaire and head of LordTech who bankrolls the corporate-sponsored Justice Gang. Sean revealed that they intentionally set aside previous portrayals of the character - such as Peter Facinelli’s in the Arrowverse’s Supergirl and Pedro Pascal’s in the DCEU’s Wonder Woman 1984 - to create a fresh, new take on Lord.
James Gunn’s Wife, Jennifer Holland, Makes An Appearance
Grace Chan joins longtime James Gunn collaborators Alan Tudyk, Michael Rooker, Pom Klementieff, and Gunn’s wife Jennifer Holland as the voices behind the Superman robots who assist him at the Fortress of Solitude. Chan voices "Twelve," Tudyk brings "Four" to life, Klementieff voices "Five," while Holland provides a voice role as well, though she remains uncredited.
Bradley Cooper and Angela Sarafyan lend their voices to Superman’s Kryptonian parents, Jor-El and Lara Lor-Van, in a poignant sequence where the Superman robots replay a recorded message as he recovers.
Michael Rosenbaum’s Voice Is In Superman
Smallville’s Lex Luthor, Michael Rosenbaum, also has a voice role.
Christopher Reeve’s Son Makes A Cameo Appearance
Christopher Reeve's son, ABC News correspondent Will Reeve, is going to make a cameo appearance as a news reporter.
James Gunn’s Dog Was 3D Modelled For Krypto
Dog actor Jolene served as the stand-in for Clark’s superpowered canine companion, Krypto - whom James Gunn affectionately describes as a “not-so-good-good-boy.” While Krypto was mainly brought to life through visual effects, his design was 3D modeled after Gunn’s own dog, Ozu. Gunn shared that Ozu, adopted shortly after he began writing Superman, inspired the character’s personality. He recalled thinking, “How difficult would life be if Ozu had superpowers?” - and that idea sparked Krypto’s creation, ultimately shaping the story in unexpected ways.
In the comics, Krypto is usually portrayed as a sleek white Labrador or Shepherd, but Gunn’s inspiration, Ozu, is a scruffy, smaller breed - giving this version of Krypto a unique twist. While Krypto appeared as a talking character voiced by Dwayne Johnson in DC League of Super-Pets (2022), this film’s Krypto remains silent, communicating through actions rather than words. In October 2024, to celebrate "Adopt a Shelter Dog" month, Gunn shared the first official image of Krypto alongside David Corenswet’s Superman, delighting fans with this fresh take on the beloved super-dog.
There Was Nearly A Superman Movie Inspired By Pixar’s Up
Before the release of Mission: Impossible – Fallout in July 2018, director Christopher McQuarrie and Henry Cavill teamed up to pitch their own fresh take on a Superman film, drawing some inspiration from the animated favorite Up (2009). However, Warner Bros. decided not to move forward with their idea. Later that same year, the studio approached James Gunn to write and direct a new Superman movie - but Gunn wasn’t immediately sure if he wanted to take on the iconic character.
James Gunn Was Initially Unsure About Taking On Superman
Later in 2018, the studio approached James Gunn to write and direct a Superman film, but he was hesitant - unsure if he wanted to take on such an iconic character. Unlike Guardians of the Galaxy (2014), which introduced a lesser-known team that allowed him creative freedom, Superman’s legacy felt like a much tougher challenge. Ultimately, Gunn chose to direct The Suicide Squad (2021) instead, calling it “the easier path.”
Henry Cavill Still Wanted To Take On Superman Again
In September, talks to bring Henry Cavill back for a cameo in Shazam! (2019) fell through due to contract issues and scheduling conflicts with his Mission: Impossible – Fallout commitments. Reports soon surfaced that Cavill was parting ways with the studio, with no immediate plans for him to reprise Superman. However, in November 2019, Cavill insisted he hadn’t given up on the character and was still eager to do the role justice. Meanwhile, Warner Bros. was uncertain about Superman’s future direction and was in discussions with high-profile talent, including J.J. Abrams - whose company Bad Robot had signed a major deal with WarnerMedia - and Michael B. Jordan, who pitched himself as a Black version of the iconic hero. By May 2020, Warner Bros. had officially shelved plans for a Man of Steel sequel, though Cavill was reportedly in talks to appear in another DC project.
Michael B. Jordan Could Have Been Superman
Warner Bros. found itself at a crossroads with Superman, exploring fresh directions by courting “high-profile talent” to reshape the iconic hero. Among those in talks were J.J. Abrams - whose company Bad Robot had just signed a major deal with WarnerMedia - and Michael B. Jordan, who boldly pitched himself as a Black Superman. In February 2021, it was announced that acclaimed writer Ta-Nehisi Coates would pen a new Superman film with Abrams producing. The project was expected to cast a Black actor in the role, fueling speculation that Jordan might be stepping into the legendary cape.
The Warner Bros Discover Merger Led To James Gunn’s Superman
In April 2022, the merger of Discovery, Inc. and WarnerMedia gave birth to Warner Bros. Discovery (WBD), led by president and CEO David Zaslav. With this new leadership, a major overhaul of DC Entertainment was on the horizon. Zaslav set out to find a visionary leader - someone on the level of Marvel Studios’ Kevin Feige - to steer the DC brand. Recognizing that DC lacked a “coherent creative and brand strategy” and that Superman was being underutilized, the company sought fresh direction. Meanwhile, James Gunn had long been pondering his own vision for Superman, and by late August 2022, he was brought on board to develop a new Superman film - one that wouldn’t be a Man of Steel sequel or tied to the previous DCEU. Zaslav even spent time collaborating closely with Gunn during the scriptwriting process, signaling a new era for the iconic hero.
At the end of October 2022, James Gunn and The Suicide Squad producer Peter Safran were named co-chairs and co-CEOs of the newly established DC Studios. Remarkably, within just a week of stepping into their roles, the duo had already begun crafting an ambitious eight-to-ten-year blueprint for a fresh DC Universe (DCU) - a “soft reboot” designed to reimagine and revitalize the legacy of the DCEU. By mid-November, Gunn’s involvement became public knowledge as he was officially revealed to be writing a new DC film, kicking off an exciting new chapter for the franchise.
Henry Cavill Was On The Black Adam Post Credit Sequence
Henry Cavill surprised fans with a cameo in the post-credits scene of Black Adam (October 2022), sparking rumors that Warner Bros. was once again eyeing a Man of Steel sequel led by Cavill. Producer Charles Roven was on board, and the studio began searching for writers to bring the project to life. They hoped to have Christopher McQuarrie direct, but his busy schedule - tied up with Mission: Impossible – Dead Reckoning (2023) and Mission: Impossible – The Final Reckoning (2025) - made his involvement unlikely.
Dwayne Johnson Wanted A Black Adam vs. Superman film
Henry Cavill’s cameo in Black Adam came with the green light from Warner Bros. film chiefs Michael De Luca and Pamela Abdy, after the star himself, Dwayne Johnson, personally pitched the idea to them. Johnson enthusiastically began promoting the concept of a Black Adam vs. Superman showdown featuring Cavill. While Cavill signed a one-off deal for Black Adam, he only had a verbal agreement to continue as Superman in future DCEU projects. Still, he publicly confirmed his return to the iconic role, describing his cameo as just a “very small taste” of what’s to come - and promised that Superman’s future would be “enormously joyful.”
James Gunn Wanted To Create A Younger Version Of Superman
In December 2022, James Gunn emphasized that Superman was a top priority - if not the biggest - for DC Studios, before officially announcing that he was writing a new Superman film. This fresh take would spotlight a younger version of the Man of Steel, meaning Henry Cavill would not be returning in the role. Gunn was also a strong contender to direct the film. Rather than retelling Superman’s origin story, the film would explore Clark Kent’s early days as a reporter, delving into his interactions with key figures like Lois Lane. Gunn and producer Peter Safran personally met with Cavill to explain their creative direction and discussed the possibility of collaborating with him in a different capacity down the line.
Superman Was Released On James Gunn’s Father’s Birthday
On January 31, 2023, James Gunn and Peter Safran unveiled the first wave of projects for their new DC Universe slate, kicking off with Chapter One: Gods and Monsters. Leading the charge was their Superman film, officially titled Superman: Legacy, set to hit theaters on July 11, 2025 - a date chosen to honor the birthday of Gunn’s late father.
Gunn revealed that his father’s passing deeply influenced the screenplay, and though he was initially hesitant to direct, Safran and others encouraged him to take the helm. Gunn found a personal connection in exploring Superman’s dual heritage: his noble Kryptonian parents and his grounded, adoptive family from Smallville, Kansas. This emotional core helped shape the character in a new way. In April, Gunn teased that the film’s tone would be distinct from his Guardians of the Galaxy series and even hinted at the possible appearance of Superman’s loyal dog, Krypto.
Superman Was Inspired By The Animated Superman Shorts
The film draws inspiration from some of Superman’s most iconic portrayals across different mediums. It pays homage to the classic animated shorts from Fleischer Studios (1941–1943) and the beloved Superman: The Animated Series (1996–2000) from the DC Animated Universe. Additionally, the story weaves in influences from standout comic runs like Superman: Birthright (2003–04) by Mark Waid, Leinil Francis Yu, and Gerry Alanguilan; the thrilling 2008 “Brainiac” arc in Action Comics by Geoff Johns and Gary Frank; and the epic crossover Superman: Ending Battle (2002) by Johns, Joe Casey, Joe Kelly, and Mark Schultz. The film also nods to Superman for All Seasons (1998) by Jeph Loeb and Tim Sale, the Kingdom Come Elseworlds series (1996) by Waid and Alex Ross, Morrison’s influential Action Comics run, and the classic story Whatever Happened to the Man of Tomorrow? (1986) by Alan Moore and Curt Swan - blending the best of Superman’s rich legacy into a fresh, new adventure.
Superman Has The Same Production Designers As Guardians Of the Galaxy
Production design, costume design, and casting kicked off in April 2023, bringing together a talented creative team. Production designer Beth Mickle and costume designer Judianna Makovsky, both of whom collaborated on The Suicide Squad and James Gunn’s Guardians of the Galaxy Vol. 3 (2023), returned to craft the look and feel of this new Superman chapter.
David Corenswet Was The Top Choice For Superman
James Gunn was on the lookout for an actor to embody Superman’s core humanity - someone who radiated kindness, compassion, and felt like “somebody you want to give a hug.” By early May 2023, audition tapes for the key roles of Superman, Lois Lane, and Lex Luthor had started rolling in. While storyboarding the film later that month, Gunn began reviewing these auditions. It was during this process that he watched the 2022 film Pearl and was immediately struck by David Corenswet’s standout performance. Having already expressed his passion for playing Superman, Corenswet’s audition quickly rose to the top of Gunn’s list, leading to a screen test scheduled for early June.
Jacob Elordi Declined To Read For Superman
Several actors were in the running for the role of Superman, including Jacob Elordi, Tom Brittney, and Andrew Richardson - though Elordi ultimately chose not to audition. Other contenders like Patrick Schwarzenegger, Pierson Fodé (known from the Supergirl TV series), and Jack Quaid, the voice of Superman in My Adventures with Superman (2023–present), submitted self-tapes. Interestingly, Patrick Schwarzenegger’s audition carried a bit of legacy: his father, Arnold Schwarzenegger, famously campaigned for the same role back in the 1978 Superman film.
Rachel Brosnahan’s Husband Read Superman For Her Audition
For the role of Lois Lane, several talented actresses - Emma Mackey, Rachel Brosnahan, Samara Weaving, and Phoebe Dynevor - put themselves to the test, with Dynevor emerging as one of the final contenders. Brosnahan took a unique approach by filming her audition alongside her husband, Jason Ralph, who helped bring Superman’s lines to life.
Nicholas Hoult Became Lex Luthor Because Of The Batman (2022)
Nicholas Hoult, who narrowly missed out on playing Bruce Wayne in The Batman (2022), was initially considered for the role of Lex Luthor. However, Hoult decided to set his sights on Superman instead, feeling that while he could portray Luthor effectively, his heart was set on embodying the Man of Steel. Meanwhile, James Gunn weighed options among A-list actors he had worked with before, reportedly even discussing the part with Guardians of the Galaxy Vol. 3’s Bradley Cooper.
The Potential Supermans Read With Emma Mackey As Lois Lane
In mid-June 2023, the stakes were raised with in-person screen tests held at Warner Bros. Studios in Burbank, California. James Gunn and Peter Safran were on hand as the actors stepped into full makeup and costume to bring Clark Kent and Lois Lane to life. The pairs tested included Hoult and Brosnahan, Brittney and Dynevor, and Corenswet and Mackey. Following this, the actors vying for Clark Kent took the next step - suited up as Superman - and tested opposite Mackey, bringing the iconic hero to life right before the filmmakers’ eyes.
The Potential Superman’s Wore Henry Cavill’s Old Superman Suit
For the screen tests, one of Henry Cavill’s original DCEU Superman suits - worn and battle-scarred - was put back into action. Gunn joked that Tom Brittney “messed it up,” but it was David Corenswet who really took it to the limit, ultimately tearing the suit to shreds with his taller frame.
James Gunn Called David Corenswet While He Filmed Twisters
James Gunn carefully edited the screen tests into a compelling reel for a decision-making committee that included Warner Bros. Discovery’s David Zaslav. On June 27, the big news dropped: David Corenswet was officially cast as Superman, with Rachel Brosnahan stepping into the role of Lois Lane. Gunn personally called both actors to share the exciting news. When offering the Superman role to Corenswet - who was busy filming Twisters (2024) - Gunn made one heartfelt request: to bring kindness and respect to everyone on set, inspired by the professionalism of Chris Pratt and John Cena, who had set the bar high in their own superhero journeys.
Alexander and Bill Skarsgård Could Have Played Lex Luthor
Brothers Alexander and Bill Skarsgård were both in the running for the role of Lex Luthor, keeping fans on the edge of their seats. While it wasn’t initially clear if Nicholas Hoult would come back to audition for Luthor, James Gunn reached out to him - and once Hoult realized how perfectly he fit the iconic villain, he eagerly accepted the challenge.
Nathan Fillion and Isabela Merced Were Cast Due To Other DC Projects
On July 11, 2023 - exactly two years before the film’s release date - the superhero lineup got even more exciting with the casting announcements of Isabela Merced as Kendra Saunders, aka Hawkgirl, Edi Gathegi as Mister Terrific, and Nathan Fillion as Guy Gardner, the Green Lantern. Fun fact: Merced had previously tested for Barbara Gordon/Batgirl in the unreleased DCEU Batgirl film, while Fillion, a familiar face in James Gunn’s projects, had voiced Green Lantern Hal Jordan in animated shows and starred in The Suicide Squad as Cory Pitzner/T.D.K. The very next day, Anthony Carrigan, who had once expressed a desire to play Lex Luthor, landed the role of Rex Mason, also known as Metamorpho - adding even more depth to this fresh new Justice Gang.
Why Does Superman Have Such A Large Cast?
Addressing concerns that a crowded superhero lineup might overshadow the story of Superman and Lois Lane, James Gunn reassured fans that their journey remains at the heart of the film. The other heroes were brought in not just to add spectacle, but to deepen Clark’s story - showcasing his relationships with colleagues and fellow superheroes, and revealing how these connections shape his values and the choices he makes along the way.
Jason Momoa Was Rumored To Be Playing Lobo In Superman
Jason Momoa, known for his role as Aquaman in the DCEU, was rumored the next month to be eyeing the role of Lobo, either in this film or a standalone project. He ultimately landed the part for the upcoming DCU film Supergirl (2026), originally titled Supergirl: Woman of Tomorrow. Meanwhile, Milly Alcock was cast as Superman’s cousin, Kara Zor-El - aka Supergirl - who is set to make her first appearance in Superman: Legacy before leading her own film. Alcock took part in auditions and screen tests in full costume on the Superman: Legacy set in Atlanta earlier that January, with her involvement officially confirmed in January 2025.
One Of The Most Expensive Superhero Films Ever Made?
Pre-production kicked off in Ohio in early February 2024, with the Ohio Department of Development announcing that Superman: Legacy would be partially filmed in Cleveland and Cincinnati. The production secured over $11 million in state tax credits, tied to a $37 million local spend, as part of its overall reported production budget - originally pegged at a staggering $363.8 million. However, James Gunn pushed back on that figure, noting it would rank among the priciest superhero films ever made. Later reports adjusted the net production budget to around $255 million after factoring in incentives and tax breaks.
Principal Photography Began On Superman’s Birthday
Principal photography began on February 29, 2024, which is Superman's birthday in the comic books!
Superman’s Working Title Was “Genesis”
Filming occurred under the working title Genesis.
Superman Was Filmed Entirely On IMAX Cameras
Henry Braham returned as cinematographer, bringing his expertise from the later Guardians of the Galaxy films, The Suicide Squad, and The Flash. The entire movie was captured using IMAX-certified Red Digital Cinema cameras, ensuring every frame delivers stunning, immersive visuals on the big screen.
The Trailer Interview Scene Was 12 Minutes Long
David Corenswet and Rachel Brosnahan filmed an intense 12-minute interview scene that director James Gunn said accounted for about ten percent of the entire movie, all captured in just two days. Gunn praised their on-screen chemistry as truly "palpable," a powerful connection that shines through and anchors the film’s emotional core.
His Girl Friday Was A Major Influence For Kent and Lane
The 1940 classic His Girl Friday served as a key inspiration for capturing the dynamic between Superman and Lois Lane in the film. Their relationship is portrayed as an "equal match," blending a "longing romance" with sharp, witty banter - channeling the comedic style of Preston Sturges to bring a fresh, electric energy to their connection.
Superman Was Filmed All Over Northeast Ohio
Filming moved to Northeast Ohio on June 14, with scenes shot at Headlands Beach State Park in Mentor. Over the next six weeks, the production transformed downtown Cleveland into Superman’s world, capturing iconic spots like Ontario Street, the Cleveland Greyhound Station, Public Square, the Detroit–Superior Bridge, PNC Plaza, Progressive Field, and the Cleveland Arcade. The Huntington Bank Building, Key Tower, and Soldiers' and Sailors' Monument all made appearances in Public Square. Notably, the Leader Building was cleverly used as the Daily Planet’s headquarters, while Key Tower doubled as the base for Stagg Enterprises.
John Williams “Superman March” From 1978 Was Used
In February 2024, it was announced that John Murphy would compose the score for the film, following his work on The Suicide Squad, The Guardians of the Galaxy Holiday Special (2022), and Guardians of the Galaxy Vol. 3. By December, James Gunn confirmed that Murphy was incorporating a fresh take on John Williams’s iconic "Superman March" from the 1978 Superman film. Gunn, who regards Williams’s score as one of the greatest ever, saw this musical nod as a heartfelt connection to the legacy of Superman on screen. Unlike his previous superhero projects, this film features fewer licensed songs, focusing more on an original score. In April 2025, David Fleming was announced as a collaborator, sharing credit with Murphy for the film’s music.
Peter Safran’s Daughter Is On The Superman Soundtrack
On the soundtrack, producer Peter Safran’s daughter, Lou Lou, teams up with American rock band Foxy Shazam for a special track. Lou Lou and the band’s lead vocalist, Eric Nally, share vocal duties on the song, which was co-written by James Gunn and Nally, adding a unique, personal touch to the film’s musical lineup.
There Has Been Anger About The Red Underpants
In early May, James Gunn dropped the first official image of David Corenswet donning the iconic Superman suit. The shot captures Superman mid-suit-up, standing tall against the backdrop of an alien threat looming ominously. Fans and critics alike zeroed in on one standout detail: the return of the classic red trunks, a bold choice not seen since Superman Returns (2006) and briefly teased in Superman & Lois (2021).
The costume also features a sleek high collar, nodding to Jim Lee’s New 52 redesign from 2011 - a look that famously ditched the red trunks. This blend of classic and modern design sparked plenty of buzz, with speculation swirling about how Superman’s character will be shaped in this new film and what formidable dangers he’ll face.
James Gunn Wanted Superman Marketed Like Barbie
At the end of February 2025, DC Studios brought on Ricky Strauss - formerly a marketing exec at Apple TV+ and Disney - to consult on the marketing strategy for the Superman film. This move came after Warner Bros.’ global marketing chief Josh Goldstine left the company the previous month. Producer Peter Safran highlighted how David Zaslav, the CEO of Warner Bros. Discovery, had “rallied the entire company” behind the project, aiming to replicate the kind of wide-reaching, enthusiastic support seen with recent Warner Bros. hits like Barbie (2023).
Superman Being Named “An Immigrant” Has Annoyed Some American Voters
Leading up to the film’s release, James Gunn emphasized that Superman is fundamentally “the story of America” - an immigrant arriving from elsewhere who embodies basic human kindness, a value he felt society had lost. This message, voiced amid the politically charged atmosphere of mass deportations during Donald Trump’s second presidential term, sparked backlash from some Trump supporters and members of the MAGA movement. Fox News labeled the film “Superwoke,” but Gunn pushed back, clarifying that the film is meant for “everyone” and is ultimately “about kindness,” a universal theme he believes all audiences can connect with.
A Lawsuit Was Dismissed Over The Ownership Of International Copyright
In January 2025, the estate of Superman co-creator Joe Shuster filed a lawsuit against Warner Bros. Discovery (WBD), claiming that distribution rights for the film had reverted to them in certain international territories - specifically the United Kingdom, Ireland, Australia (since 2017), and Canada (since 2021) - based on differing copyright laws in those countries.
In response, WBD filed a motion to dismiss the lawsuit two months later, referencing prior similar copyright cases that were rejected. The lawsuit was dismissed in April due to a lack of international jurisdiction. However, the estate refiled the lawsuit in the New York Supreme Court in May, requesting an injunction. This motion was denied in early June.
Nathan Fillion Has Worked With James Gunn 7 Times
Nathan Fillion’s appearance as Guy Gardner marks his seventh collaboration with director James Gunn, maintaining their longstanding tradition of Fillion featuring in every film Gunn directs, thanks to their close friendship.
David Corenswet Gained 40lb Of Muscle For Superman
Personal trainer Paolo Mascitti confirmed that David Corenswet gained 40 pounds of muscle before filming began. “David had already been training hard before I met him, but he’s naturally quite lean. At 6'4" (1.93 meters), we aimed to add more bulk, taking him from around 200 pounds to 240 pounds. However, some of that mass will be trimmed as he continues to tone up.” Interestingly, Christopher Reeve followed a similar training regimen in the late 1970s when he played Superman.
Superman’s Crest Is Based on The “Kingdom Come” Miniseries
The Superman emblem is inspired by Alex Ross’s original design from the Kingdom Come miniseries, but with yellow filling instead of black. This design previously appeared during the Crisis on Infinite Earths crossover, where Brandon Routh reprised his role from Superman Returns (2006). The updated cinematic symbol also features a yellow border, echoing Superman’s look from the 1930s and ’40s. According to James Gunn, the costume uses real textured materials rather than printed inks.
This is the first Superman film since Superman IV: The Quest for Peace (1987) where Superman sports a yellow "S" symbol on the back of his cape.
Metropolis Has Important Superman Street Names
As part of the Metropolis setting, detailed maps of the downtown area were used on set, showing street names and the general layout of the city. Many of these street names pay tribute to notable figures connected to the Superman character and franchise, including George Reeves, Christopher Reeve, Margot Kidder, Richard Donner, David S. Goyer, Mark Waid, Grant Morrison, Alan Moore, John Byrne, Curt Swan, Geoff Johns, Gary Frank, and several others.
Superman & Lois Ended On The CW When Superman Was Announced
During the film’s production, it was announced that the CW series Superman & Lois (2021) would conclude with its fourth season, despite originally being planned for seven seasons. Brad Schwartz, president of entertainment at the CW, attributed the decision to Warner Bros. not wanting multiple competing Superman projects in the market due to the new film. However, Elizabeth Tulloch, who portrayed Lois Lane on the show, defended the cancellation, pointing instead to management changes - such as Nexstar’s acquisition of the CW and Warner Bros.’ CEO transitions during the series’ run - as the real reasons behind it.
This Is Jimmy Olsen’s First Cinematic Appearance Since 2006

Eve Teschmacher Returns To The Superman World
Sara Sampaio plays Eve Teschmacher, a character who made her debut outside the comics in Superman (1978), and who predates the more familiar Lex Luthor personal assistant, Mercy Graves, introduced in Superman: The Animated Series (1996).
The First Superman Trailer Was Watched 250 Million Times in 24 Hours

James Gunn Was Inspired By Godzilla Minus One (2023)
James Gunn cited Godzilla Minus One (2023) as a major influence on the film, stating that he aimed to blend elements such as giant monsters, robots, flying dogs, and other superheroes. 'My goal was to create something akin to Godzilla Minus One - a film that showcased Godzilla but also delivered powerful human drama,' he explained.
Lois Lane Will Be Older Than Clark Kent In This Superman
Rachel Brosnahan is the sixth actress to play Lois Lane who is older than the actor portraying Superman. She is four years older than David Corenswet, following Elizabeth Tulloch (six years older than Tyler Hoechlin), Amy Adams (nine years older than Henry Cavill), Teri Hatcher (two years older than Dean Cain), Lesley Ann Warren (three years older than David Patrick Wilson), and Margot Kidder (four years older than Christopher Reeve).
One of the main criticisms of Superman Returns (2006) was that Kate Bosworth appeared too young to convincingly portray a seasoned journalist with a Pulitzer Prize and a five-year-old child, as she was only 22 during principal photography. To avoid similar backlash, director James Gunn intentionally cast an older actress, with Rachel Brosnahan turning 34 during filming.
Nicholas Hoult Originally Auditioned For A Hero Not A Villain
Nicholas Hoult previously auditioned for the role of Bruce Wayne/Batman in The Batman (2022) and later for Superman in this film, before ultimately being cast as Lex Luthor. His journey - from vying for the hero to landing the role of the villain - has drawn comparisons to Tom Hiddleston, who famously became Loki after losing the role of Thor to Chris Hemsworth in Thor (2011).
James Gunn Included Comic Book Creators On Set
James Gunn invited several renowned comic book creators to the set, including Frank Quitely, Jim Lee, Kevin Maguire, Scott Snyder, John Ostrander, Jerry Ordway, Dan Jurgens, and Jason Aaron.

David Corenswet and Nicholas Hoult Loved Smallville
Both David Corenswet (Clark Kent/Superman) and Nicholas Hoult (Lex Luthor) have acknowledged watching Smallville (2001) during their youth and becoming familiar with that show's portrayals of Clark and Lex. Hoult even shared this directly with Michael Rosenbaum - the actor who played Lex Luthor on Smallville - during an appearance on his podcast Inside of You with Michael Rosenbaum (2018).
Nathan Fillion Is Regularly Green Lantern!
Nathan Fillion plays Guy Gardner in this film, having previously voiced Green Lantern in several DC animated features, including Green Lantern: Emerald Knights (2011), Justice League: Doom (2012), Justice League: The Flashpoint Paradox (2013), among others.
Nicholas Hoult Was Inspired By “All-Star Superman”
Nicholas Hoult has said that the panel from All-Star Superman where Lex compares his "real muscles" to Superman's played a key role in shaping his portrayal of Lex Luthor. Hoult explained, "That kind of captures, in my mind, the element of Lex." (See All-Star Superman (2011) for reference.)
Superman Has Several Cinematic Debuts From The DC Comics
This film marks the cinematic debut of DC Comics characters Mr. Terrific, Hawkgirl, Krypto, and Cat Grant - the latter appearing in live-action after multiple TV and animated versions. It also features the live-action debut of Metamorpho, Guy Gardner (Green Lantern), Ultraman, Superman’s Kryptonian robots, and the Engineer.
Anthony Carrigan Was In Make Up 5-6 Hours For Metamorpho
Anthony Carrigan shared his experience wearing the makeup for Metamorpho, telling Entertainment Weekly, “There were things glued onto me, then painted details, and more pieces glued on top. I wasn’t just glued in - I was sewn in, completely enveloped, tied and roped in. But it was all for this incredible costume.” Carrigan, who has alopecia areata, explained that James Gunn specifically cast him because he deeply understood, on a human level, the feeling of being different and the sense of a curse. “James wanted someone who could bring the human struggle and torment to the role, and I think that really comes through,” he said.
The film will hint at Metamorpho’s backstory, including the involvement of Stagg Industries - a company straight from the comics tied to the character’s origins - though fans will meet Metamorpho already fully formed. A self-described fan of practical effects, Carrigan revealed the transformation process took about five to six hours in the makeup chair. “It’s worth it because you can actually feel the texture - your brain notices the difference,” he noted.
As for coping with the long sessions, Carrigan joked it might be thanks to growing up with two older sisters who would put makeup on him. “I go into a tranquil state and actually have a good time. The hardest part is usually the last hour,” he said.
Amy Adams Praised Rachel Brosnahan’s Casting
Previous Lois Lane Amy Adams praised Rachel Brosnahan’s casting in the role. Interestingly, Adams’ film American Hustle (2013) was shot around Boston during the time of the 2013 Boston Marathon - events that were later dramatized in Brosnahan’s film Patriots Day (2016).
James Gunn’s Superman promises to be a reinvention of the iconic hero that remains faithful to the spirit of the character while introducing fresh perspectives and deeper storytelling. These behind-the-scenes details and lesser-known facts highlight the thoughtful care being poured into this new vision of the Man of Steel. As the 2025 release approaches, it’s clear that this Superman isn’t just faster than a speeding bullet, he’s arriving with a new legacy in the making.
