15 Actors Who Were Almost Cast as Your Favorite Avengers

At the height of his fame from The Office, Krasinski was widely rumored to be the front-runner for the role of Steve Rogers, the stouthearted everyman-turned-supersoldier.

The star of Disney's sci-fi reboot Tron: Legacy was also listed among the top candidates for the role of Cap in early 2010, around the same time that Marvel Studios became a Disney subsidy.

According to the same MTV report that named Krasinki and Hedlund, Crawford was also among the top names pursued for Captain America.

Frankly, this one doesn't seem shocking at all. Skarsgard admitted to MTV in 2009 that he'd come very close to wielding Thor's hammer.

"I met with [Marvel Studios Chief] Kevin [Feige] a few times and the director [Kenneth Branagh]," Skarsgard said, even noting that he got to do a costume test. "That was pretty fun."

Like Hiddleston, Rockwell initially was considered for one of the marquee Avengers roles, but instead made his Marvel debut as a villain — in his case, as Iron Man 2's slimy Justin Hammer.

"At one point, Jon [Favreau] had called me about possibility screen-testing for the part of Tony Stark in Iron Man. And whatever happened, I think I was out of the running. Robert [Downey Jr.] just killed it, you know, and I never heard anything after that," Rockwell told The A.V. Club. "So in a way, I think Jon was basically saying, 'This [playing Hammer] is your chance to be Tony Stark. This will be your version of Tony Stark.' We gave him the glasses and kind of sleazed him up a little. But that's exactly right. It was a chance to do Tony Stark."

Olyphant came very close to landing the role of Tony Stark, but there was just one little problem: he ended up screen-testing the same day as Robert Downey Jr., and, well, we know how that went!

"A wonderful actor, Robert Downey Jr. and I, we screen tested on the same day," Olyphant said on Conan in 2017. He then joked, "And I'm still waiting to hear back!"

According to a Rotten Tomatoes report from 2006, The X-Files star was apparently the first choice to replace Eric Bana, who dropped out of what eventually became The Incredible Hulk due to plans to make it a direct-to-video release. In the end, though, the role went to Edward Norton, who was then replaced again by Mark Ruffalo for the full-fledged Avengers franchise.

Ackles auditioned for Captain America and failed to land the role, but reportedly impressed Marvel execs so much that they offered him the role of Hawkeye instead. Unfortunately, Screen Rant reported, Ackles had to turn it down because the shooting schedule interfered with his commitments to Supernatural.

Like her husband Krasinski, Blunt was under consideration for a role as one of the original Avengers: Black Widow. She ultimately passed on the role — as well as the role of Peggy Carter — because, as she later told Vulture, "Usually the female parts in a superhero film feel thankless: she's the pill girlfriend while the guys are whizzing around saving the world. I didn't do the other ones because the part wasn't very good or the timing wasn't right, but I'm open to any kind of genre if the part is great and fun and different and a challenge in some way."

In 2013, Ronan responded to rumors that she was under consideration for Scarlet Witch, telling The Mary Sue, "I love Joss and I love those films, and I love his handle on them and how he portrayed these kinds of superheroes. I think it's very different from what anyone else has done. So yeah, I'd love to be in it." Ultimately, though, she didn't end up playing the role, for unknown reasons.

The role of Star-Lord was a career-turning role for Chris Pratt, but if he hadn't taken the role, director James Gunn knows who would have: It's Always Sunny in Philadelphia's Glen Howerton. "There was a good chance that, if I didn't cast Chris, that I would've cast Glenn Howerton in the role," The A.V. Club reported Gunn as saying in a GQ profile of Pratt.

Wilde was apparently one of Marvel's top picks to play Gamora — she was even offered the role! In the end, she turned it down, most likely out of exhaustion with playing similar roles for years.

"People thought I could only play the badass so I'd always get those roles. It just doesn't feel very human. I got cast as a computer program in Tron: Legacy and an alien in Cowboys and Aliens. I was, like, 'There's something wrong here …'," she admitted to the Guardian in 2013, likely explaining, indirectly, her reasons for passing on Gamora.

In 2013, Variety reported that the role of Scott Lang, aka Ant-Man, was pretty much narrowed down to two actors: Gordon-Levitt and Paul Rudd. Of course, Rudd wound up snagging the role, and Gordon-Levitt, who had previously dabbled in the superhero world as future "Robin" John Blake in The Dark Knight Rises shot down the rumors as "nothing but lies" in a red carpet interview, according to Screen Crush.

Long before he took on an iconic supervillain in Joker, Phoenix was approached to play a superhero: Doctor Strange. In the end, it didn't work out, but when asked about it by CinemaBlend, Phoenix didn't seem to hold any negative feelings about the whole situation.

"I think they make some great, fun movies... I'm not a snob and I'm totally fine with... I enjoy those movies sometimes, and I think they keep the f***ing industry going in some ways, so I don't have a problem with it at all... I think everybody was really happy with how things turned out. All parties were satisfied."
