With superhero movies becoming so popular, it’s no surprise they’ve attracted many famous actors. The Marvel Cinematic Universe, in particular, has assembled a huge and talented cast to play its iconic characters. Because these comic book heroes are so well-known and beloved, finding the right actors is key to the continued success of these films.
It’s rare to imagine anyone else in a role after an actor becomes strongly associated with a character, but sometimes the first actor cast isn’t the best fit. When this happens, a new actor might take over and truly shine. This can be due to changes in the story or how the character is envisioned, but the fact is, sometimes comic book movies get the casting just right the second time around.
10) Don Cheadle as War Machine

Early in the Marvel Cinematic Universe, some characters were recast surprisingly quickly. A prime example is Colonel James Rhodes, Tony Stark’s friend, who was originally played by Terrence Howard in 2008’s *Iron Man*. Howard didn’t return for the sequel due to disagreements behind the scenes. Don Cheadle then took over the role, debuting as Rhodey in *Iron Man 2* and eventually becoming the hero War Machine.
Don Cheadle was an excellent pick for the role. He’s played War Machine many times since his debut in *Iron Man 2*, often alongside the other Avengers. Given his history of strong performances in team-based films like *Ocean’s Eleven*, and his impressive range as an actor, casting him as the second War Machine in the Marvel Cinematic Universe really paid off.
9) Ryan Reynolds as Deadpool

Ryan Reynolds is known for appearing in comic book films, but many haven’t been well-received. His most successful role by far is Deadpool, starting with two movies made by Fox as part of the *X-Men* universe. The third, *Deadpool & Wolverine*, brought the character into the Marvel Cinematic Universe. Interestingly, Reynolds’ acclaimed performance as Deadpool in the 2016 film came after he took over the role from a previous, less popular actor.
It’s ironic that Ryan Reynolds initially played Wade Wilson in *X-Men Origins: Wolverine* – the character who would eventually become Deadpool. Fans didn’t like how the character was portrayed, so Reynolds campaigned for a more faithful adaptation. This led to the Deadpool movies, where he truly shone in the role. Reynolds’ quick wit and playful personality were a perfect match for the comic book version of Deadpool, making the later films significantly better than the first attempt.
8) Emma Stone as Gwen Stacy

Sam Raimi’s *Spider-Man* trilogy had many strengths, but the third film, *Spider-Man 3*, didn’t quite measure up. While *Spider-Man 3* introduced the character of Gwen Stacy, played by Bryce Dallas Howard, she played a small role, mostly as a potential complication for Peter Parker and Mary Jane Watson’s relationship. Later, in the 2012 reboot *The Amazing Spider-Man*, Gwen Stacy was reimagined as Peter Parker’s primary love interest, staying true to many of the comic book storylines.
Emma Stone significantly improved the portrayal of Gwen Stacy in *The Amazing Spider-Man* compared to Bryce Dallas Howard’s performance. This was partly because the character was more central to the plot, but Stone’s acting was also a major factor. She played Gwen as smarter and more engaging, and her connection with Andrew Garfield’s Peter Parker felt incredibly natural. Ultimately, Emma Stone delivered a fantastic and memorable take on the character.
7) Channing Tatum as Gambit

The film *X-Men Origins: Wolverine* introduced several Marvel mutants to audiences, including the popular character Gambit. Taylor Kitsch played Gambit in his first live-action appearance, but both his performance and the movie’s story were disappointing. He didn’t reprise the role, and there were later discussions about a standalone Gambit film starring Channing Tatum.
Although a standalone Channing Tatum-led *Gambit* movie fell through, he ultimately got to play the character on film. Tatum made a cameo as Gambit in *Deadpool & Wolverine*, and his short scene was a highlight for many viewers. He convincingly portrayed the character, proving that a live-action *Gambit* can work well with the right approach.
6) Michael Keaton as Batman

In the 1960s, Batman became a live-action sensation with a popular movie and TV show starring Adam West as the hero. This version was known for its playful and over-the-top style and remained incredibly popular for over twenty years. Then, in 1989, Tim Burton’s *Batman* movie arrived, starring Michael Keaton. While some questioned Keaton’s casting at first, he quickly proved to be a great fit for the role, offering a different take on the character compared to Adam West.
Michael Keaton’s Batman blended the humor of the 1960s series with a much more serious and intense tone. Tim Burton’s dark and fantastical vision for Gotham City and Batman himself suited Keaton perfectly, allowing him to capture the hero’s strange but admirable qualities with just the right mix of seriousness and lightheartedness. Keaton’s performance was key to the huge success of Burton’s films, demonstrating how important casting can be in shaping how audiences see a character.
5) Mark Ruffalo as the MCU’s Hulk

The Marvel Cinematic Universe has been criticized for not utilizing some talented actors to their full potential, and Edward Norton is often cited as an example. He played Bruce Banner, aka the Hulk, in the 2008 film *The Incredible Hulk*. Although Norton is a skilled actor, his portrayal of the character wasn’t considered a strong fit. When disagreements over his contract led to him being replaced, many fans weren’t optimistic about Mark Ruffalo taking on the role.
Mark Ruffalo quickly proved he was ideal for the role of Bruce Banner. He brought a unique energy to the character – a bit more grounded and quirky – adding layers of complexity and sadness. Since then, he’s consistently delivered a strong performance, and the decision to cast him is now widely considered one of the smartest moves Marvel made early on in the MCU.
4) Tom Hardy as Venom

Spider-Man is a Marvel legend, and Venom is one of its most popular anti-heroes. The character, a sometimes-villainous alien symbiote, first appeared on screen in Sam Raimi’s *Spider-Man 3*, with Topher Grace playing Eddie Brock, Venom’s human host. However, many fans felt Grace wasn’t the right fit for the role, finding him too slight and comedic, and the portrayal of Venom wasn’t well-received when the movie came out.
When Venom got his own movie in 2018, Tom Hardy took over the role of Eddie Brock. Hardy’s portrayal of Venom was a success, as he perfectly captured the character’s flaws and charm, as well as his complicated connection with the symbiote. He brought the ideal combination of physicality, a rebellious attitude, and humor to the role, proving it was the right casting choice this time around.
3) Karl Urban as Judge Dredd

I’ve been a fan of Judge Dredd for years, and it’s amazing to think he first appeared way back in 1977! He’s become a real icon, even if he doesn’t always get the same attention as heroes from Marvel or DC. I remember when Sylvester Stallone played him in the 1995 movie, and honestly, it didn’t really click with me or a lot of the other fans. It just didn’t feel quite right.
The character of Judge Dredd returned to the big screen in 2012 with the film *Dredd*, starring Karl Urban. Urban was an excellent choice for the role, as he clearly understood the core of the character: a stoic, emotionless demeanor and unwavering dedication to the law. He perfectly captured Dredd’s cool composure and intimidating presence, making this a much more faithful and successful movie adaptation than the first attempt.
2) Paul Dano as The Riddler

Few Batman villains truly become iconic. Though the Riddler is a frequent foe in comics and animation, he hasn’t fared well in live-action films. Tim Burton once planned to use the Riddler, but it never happened. The version audiences saw in the 1995 film *Batman Forever*, played by Jim Carrey, was largely considered a weak portrayal of the character.
The 2022 film *The Batman* finally got the Riddler right with its live-action portrayal. Paul Dano played the villain, and his version of the character was completely reimagined, taking inspiration from the Zodiac Killer and aspects of online culture. Dano’s Riddler struck a perfect balance between unsettling and strange, demonstrating that staying true to the comics isn’t essential as long as the actor embodies the character effectively.
1) Hugh Jackman as Wolverine

Hugh Jackman is so well-known as Wolverine that many people don’t realize he wasn’t the original choice for the part. Dougray Scott was first cast as the character in the 2000 film *X-Men*, but scheduling issues meant he had to drop out. This led to Hugh Jackman being cast as a replacement. So, while Scott never played Wolverine on screen, he was the first actor chosen for the role.
Hugh Jackman was the ideal actor to play Wolverine, and his portrayal has become legendary. He’s widely considered the best person to have brought the character to life, becoming one of the most popular superheroes in film. Although Dougray Scott was originally cast, it’s hard to picture anyone other than Jackman as the fierce, animalistic mutant we’ve all come to love.
