18 Actors Who Were Almost Cast as Superheroes
Hollywood casting decisions can make or break a superhero franchise. Sometimes the stars align perfectly, giving us iconic performances that define characters for generations. Other times, studios go in completely different directions, leaving us to wonder what might have been.
The world of superhero casting is full of near-misses and surprising alternatives. Here are 18 actors who came incredibly close to donning the cape and cowl.
Tom Cruise as Iron Man

Before Robert Downey Jr. became synonymous with Tony Stark, Tom Cruise was seriously considered for the role. The Mission: Impossible star met with Marvel executives multiple times and was reportedly very interested in the project.
However, Cruise wanted too much creative control over the character and story direction, which didn’t align with Marvel’s vision for launching their cinematic universe.
Will Smith as Neo in The Matrix

While not technically a traditional superhero movie, The Matrix’s Neo is certainly a superhuman character. Will Smith was offered the role but turned it down to star in Wild Wild West instead.
Smith later admitted he didn’t fully understand the concept when it was pitched to him, and he couldn’t envision how the groundbreaking special effects would work.

John Krasinski as Captain America

The Office star actually screen-tested for Steve Rogers and made it to the final rounds of casting. Chris Evans initially turned down the role multiple times before accepting, which gave other actors like Krasinski a real shot.
Krasinski has said the audition process was intense, but he ultimately didn’t get the part that would define Evans’ career.
Emily Blunt as Black Widow

Scarlett Johansson wasn’t the first choice for Natasha Romanoff. Emily Blunt was originally cast in the role but had to drop out due to scheduling conflicts with Gulliver’s Travels.
The decision haunted Blunt for years, especially as she watched the Marvel Cinematic Universe explode in popularity and Johansson become a major action star.
Joaquin Phoenix as Doctor Strange

Before Benedict Cumberbatch brought his distinctive voice to the Sorcerer Supreme, Joaquin Phoenix was Marvel’s top choice. Phoenix met with the studio extensively but ultimately decided the commitment to multiple films wasn’t right for him at that point in his career.
The role required signing on for several movies, which Phoenix felt would limit his artistic freedom.

Jake Gyllenhaal as Spider-Man

When Tobey Maguire injured his back during the filming of Spider-Man 2, Jake Gyllenhaal was brought in as a potential replacement. Gyllenhaal actually did extensive preparation for the role, including physical training and costume fittings.
Maguire ultimately recovered and returned to finish the trilogy, but Gyllenhaal’s preparation wasn’t wasted—he later played Mysterio in the Marvel Cinematic Universe.
Rachel McAdams as Pepper Potts

The Notebook star was offered the role of Tony Stark’s assistant-turned-CEO but passed on it. McAdams was looking to avoid blockbuster franchises at the time and wanted to focus on smaller, more character-driven projects.
Gwyneth Paltrow ended up taking the role and appeared in multiple Iron Man and Avengers films.
Ryan Reynolds as Deadpool (Originally)

This one’s a bit different because Reynolds did play Deadpool, but his first attempt in X-Men Origins: Wolverine was drastically different from the character fans know and love. The version in that film barely resembled the comic book Deadpool, with his mouth sewn shut and completely different powers.
Reynolds spent years fighting to get a proper Deadpool movie made, which finally happened in 2016.

Mel Gibson as Wolverine

Long before Hugh Jackman made the character his own, Mel Gibson was considered for the role of Logan. This was back when the X-Men movies were first being developed in the late 1990s.
Gibson was interested but ultimately passed, feeling he was too old for the role and the physical demands it would require.
Leonardo DiCaprio as Spider-Man

During the early development of the first Spider-Man movie in the 1990s, Leonardo DiCaprio was attached to star. James Cameron was set to direct at the time, and DiCaprio was coming off his success in Titanic.
The project went through multiple iterations and studios before eventually landing at Sony with Tobey Maguire in the lead role.
Dougray Scott as Wolverine

Most people don’t realize Hugh Jackman wasn’t the original choice for Wolverine. Dougray Scott was actually cast in the role but had to drop out due to scheduling conflicts with Mission: Impossible 2.
The shoot for that Tom Cruise film ran over schedule, preventing Scott from joining the X-Men cast and changing the trajectory of both actors’ careers.

Sandra Bullock as Wonder Woman

In the early 2000s, when Joss Whedon was developing a Wonder Woman movie, Sandra Bullock was seriously considered for the title role. Bullock was interested in taking on an action franchise but ultimately felt the script needed more work.
The project never materialized under Whedon’s direction, and it would be years before Patty Jenkins brought Wonder Woman to the big screen with Gal Gadot.
Nic Cage as Superman

This casting choice seems bizarre now, but Nicolas Cage was actually set to play Superman in Tim Burton’s planned Superman Lives movie in the late 1990s. Cage is a huge comic book fan and was excited about Burton’s darker take on the character.
The film was ultimately cancelled, but costume tests of Cage in the Superman suit have become legendary among comic book movie fans.
Charlize Theron as Wonder Woman

Before Gal Gadot was cast, Charlize Theron was a frontrunner for Wonder Woman in multiple iterations of the project. Theron had the action movie experience from films like Mad Max: Fury Road and was interested in the role.
However, by the time the current DC Extended Universe version moved forward, the studio wanted to go with a younger actress.

Stuart Townsend as Aragorn

While Lord of the Rings isn’t technically a superhero movie, Aragorn certainly fits the heroic archetype. Stuart Townsend was originally cast as the ranger-king and even began filming before being replaced by Viggo Mortensen.
Director Peter Jackson felt Townsend appeared too young for the role, despite being only two years younger than Mortensen.
Armie Hammer as Batman

Before Ben Affleck was cast as the Dark Knight in Batman v Superman, Armie Hammer was seriously considered for the role. Hammer had previously been cast as Batman in George Miller’s cancelled Justice League: Mortal movie in the mid-2000s.
He came close to landing the role again for the DC Extended Universe but ultimately lost out to Affleck.
Edward Norton as Bruce Banner

Edward Norton did play Bruce Banner in The Incredible Hulk, but he was almost replaced before filming even began. Norton wanted significant input on the script and clashed with Marvel over the creative direction.
He completed the film but was later replaced by Mark Ruffalo for The Avengers, creating one of the most notable recasting decisions in the Marvel Cinematic Universe.

Tyrese Gibson as Green Lantern

Before Ryan Reynolds took on the emerald ring, Tyrese Gibson campaigned heavily for the role of Green Lantern. Gibson was vocal about his interest in playing John Stewart, the Green Lantern from the animated Justice League series.
The studio ultimately went with Hal Jordan and cast Reynolds, though Gibson has continued to express interest in joining the DC universe.
Where These Choices Lead Us Today

These casting what-ifs remind us how different our favorite superhero movies could have been with just a few different decisions. Some actors dodged bullets by avoiding poorly received films, while others missed out on career-defining roles that could have changed everything.
The butterfly effect of Hollywood casting continues to shape the superhero landscape, with each choice creating ripples that affect entire cinematic universes. What seems like destiny in hindsight was often just the result of scheduling conflicts, creative differences, or pure chance—proving that even superheroes are subject to the unpredictable nature of show business.
