9. Chris Evans Declined The Role Three Times
The reveal of who would play Captain America kept fans on the edge of their seats. A number of actors were mentioned as being in the running, with John Krasinski, Scott Porter, Garrett Hedlund, and Jensen Ackles all reportedly testing for the role. When it was announced that former Fantastic Four star Chris Evans had been cast, though, fans were overjoyed. It's now hard to imagine anyone else as Steve, but it very nearly didn't happen; Evans turned Marvel down three times before being convinced into taking on another superhero role, and even then he would only sign a six picture contract rather than nine.
