Tom Hiddleston as Thor? Sam Rockwell as Iron Man? Sebastian Stan as Captain America? Though these casting choices sound ridiculous in hindsight, these actors’ initial auditions for those heroic parts helped all of them to land a different role in a Marvel film.
Like the evil plan of a comic supervillain, this same story keeps repeating itself behind the scenes, and it’s not hard to see why. The lead in a Marvel movie can offer up a world of possibilities, so it's understandable that actors are lining up to audition and then clawing their way to stay in the picture, no matter the specific role.
So, in the spirit of re-using actors, instead of dwelling on ‘what could have been,’ we can look to an exciting world of future possibilities, just as Marvel does. Marvel is, after all, packed to the gills with characters, and is trying to adapt as many as possible, on any medium, before the superhero craze fizzles out. And there’s no better way to sell a B-list superhero than to attach a big name actor to it, especially an actor that Marvel is already familiar with.
To wit, these are 14 actors who, regardless of the reasons why, didn’t find a part on their first try, but could still easily find another within the MCU.
