12 Stars Who Turned Down Superhero Roles (And Why)

Superhero movies are box office giants, launching careers and defining legacies, but not every actor jumps at the chance to wear a cape. From scheduling conflicts to creative doubts, some stars walk away from these iconic roles for reasons that make you rethink their choices.

Here are 12 actors who turned down major superhero parts, along with why they said no. Their decisions reshaped franchises, and I was surprised by how many missed out on roles that became legendary.

Will Smith in ‘Superman Returns’ (2006)

Will Smith was offered the role of Superman in ‘Superman Returns’, a reboot of the iconic hero’s story. He declined, wary of backlash from playing a traditionally white character after criticism for ‘Wild Wild West’ (1999).

Smith’s caution made sense at the time, given Hollywood’s history with race and casting. He later embraced superhero roles as Deadshot in ‘Suicide Squad’ (2016) and the lead in ‘Hancock’ (2008). Brandon Routh took the cape, but I didn’t notice Smith’s absence in the film’s epic scope.

Emily Blunt in ‘Iron Man 2’ (2010)

Emily Blunt was set to play Black Widow in ‘Iron Man 2’, the sequel to Tony Stark’s origin story, but a scheduling conflict with ‘Gulliver’s Travels’ (2010) forced her to pass. She later expressed regret.

Blunt’s sass would’ve been perfect for Natasha Romanoff, but Scarlett Johansson owned the role. I was so caught up in the action that I didn’t realize Blunt was almost part of the MCU. Her choice prioritized a prior commitment, but it’s a fascinating what-if.

Leonardo DiCaprio in ‘Spider-Man’ (2002)

Leonardo DiCaprio was approached for Peter Parker in Sam Raimi’s ‘Spider-Man’, a groundbreaking superhero flick. He turned it down, feeling the role wasn’t complex enough for his taste.

DiCaprio’s focus on deeper characters led him to films like ‘The Departed’ (2006). Tobey Maguire’s heartfelt Peter made the role iconic, and I didn’t miss DiCaprio’s absence while watching Spidey swing through New York.

Matt Damon in ‘Daredevil’ (2003)

Matt Damon was offered the lead in ‘Daredevil’, a gritty take on the blind vigilante. As a comic fan, he passed because he didn’t trust the script or director Mark Steven Johnson’s vision.

Damon’s gut call was spot-on—the film got mixed reviews. Ben Affleck took the part, and I was too wrapped up in the action to notice Damon’s absence. His choice kept him focused on projects like ‘The Bourne Identity’ (2002).

Joaquin Phoenix in ‘Doctor Strange’ (2016)

Joaquin Phoenix was in final talks to play Doctor Strange in the MCU’s mystical origin story but backed out at the last minute. He’s been vague about why, hinting at creative differences.

Phoenix’s intensity would’ve been wild, but Benedict Cumberbatch’s wit defined the role. I didn’t catch the near-miss while watching Strange battle dimensions. Phoenix later won an Oscar for ‘Joker’ (2019), proving he made the right call.

Jason Momoa in ‘Guardians of the Galaxy’ (2014)

Jason Momoa turned down Drax the Destroyer in ‘Guardians of the Galaxy’ because the silent, shirtless role felt too similar to his past parts, like Ronon in ‘Stargate: Atlantis’ (2004-2009).

Momoa’s choice paid off when he landed Aquaman in ‘Justice League’ (2017). Dave Bautista’s heartfelt Drax stole scenes, and I didn’t notice Momoa’s absence in the cosmic adventure. He wanted a role that let him stretch.

Tom Cruise in ‘Iron Man’ (2008)

Tom Cruise was considered for Tony Stark in ‘Iron Man’, the film that launched the MCU. He passed, feeling the project wasn’t something he could fully commit to emotionally.

Cruise’s high-energy style would’ve been fun, but Robert Downey Jr. became Tony Stark. I was so hooked on Downey’s charm that I didn’t think about Cruise. His focus on films like ‘Mission: Impossible’ worked out fine.

Josh Hartnett in ‘Batman Begins’ (2005)

Josh Hartnett was offered Batman in Christopher Nolan’s ‘Batman Begins’ but declined, worried about being typecast as a superhero after also passing on Spider-Man and Superman.

Hartnett’s fear of being pigeonholed kept him in dramas like ‘Black Hawk Down’ (2001). Christian Bale’s intense Bruce Wayne carried the film, and I didn’t miss Hartnett while Gotham came to life.

Also, he turned down the role of Superman twice!

Jessica Chastain in ‘Iron Man 3’ (2013)

Jessica Chastain was offered the role of Maya Hansen in ‘Iron Man 3’, a scientist tied to Tony Stark’s past. She turned it down due to scheduling conflicts and a desire for a more dynamic superhero role.

Chastain’s choice led her to ‘X-Men: Dark Phoenix’ (2019) as a villain. Rebecca Hall played Hansen, and I didn’t notice the swap amid the film’s explosive action. Chastain wanted a part with more kick.

Heath Ledger in ‘Batman Begins’ (2005)

Heath Ledger was considered for Batman in ‘Batman Begins’ but had no interest in superhero films at the time. He later signed on as the Joker in ‘The Dark Knight’ (2008) after the first film’s success.

Ledger’s iconic Joker performance overshadowed his earlier pass. Christian Bale’s Batman was gripping, and I didn’t think about Ledger’s absence as Bruce Wayne. His choice led to an Oscar-winning role.

Dougray Scott in ‘X-Men’ (2000)

Dougray Scott was cast as Wolverine in ‘X-Men’, the mutant team’s origin story, but production delays on ‘Mission: Impossible 2’ (2000) forced him to drop out. Hugh Jackman replaced him.

Scott’s scheduling conflict gave Jackman his breakout role. I was so drawn into Wolverine’s claws that I didn’t realize Scott was almost the feral hero. Scott continued with solid roles but never hit Jackman’s fame.

Pierce Brosnan in ‘Batman’ (1989)

Pierce Brosnan was offered Batman in Tim Burton’s ‘Batman’ but turned it down, thinking the idea of a man in tights was too silly for a serious role. He later regretted it.

Brosnan’s hesitation led to Michael Keaton’s iconic performance. I was glued to Keaton’s brooding Bruce Wayne and didn’t miss Brosnan. His focus on films like ‘GoldenEye’ (1995) suited him well.
