Chris Evans, star of comic book adaptations Fantastic Four, TMNT, The Losers, Scott Pilgrim and the forthcoming Captain America movie opened up about his being cast as Sentinel of Liberty, Steve Rogers.
Speaking at Wondercon Evans had the following to say:
I think Marvel is doing a lot of good things right now, and it's a fun character. Even if it wasn't a comic book, I think just the story of Steve Rogers is great; he's a great guy. Even if it was just a script about anybody, I would probably want to do it. So it wasn't necessarily about the comic itself.
Any time I can get in blue tights, I'll do it. It's just he's a great character, a great character to play. It just so happens to be a comic book, and that's really where I'm coming from.
I'm not a big comic book reader. I don't really have a history and a love for comic books. I didn't grow up reading them. But they're fantastic for films. You have all of these different creative people coming together trying to make something, and the director is the quarterback who's trying to bridge the gap [between] all of these different artists together with words. And a lot of times the message can be lost in translation, not all of the time, but the beautiful thing about comic books or even movies based on novels [is] you have like a blueprint.
You have a tangible thing to say, listen, this is the world we're going for, and especially for comic books, you have a color palette. You have a visual home base to kind of rook yourself in, so as an actor, it's nice knowing that at least the people behind the visual elements of the film have this kind of blueprint to work off of, and as an actor you have something to go off of too. So it's a treat – it's always nice working off of a comic book because you know what you're getting into beforehand.
I've been seriously sceptical about Evans' casting. Well, more violently opposed than sceptical, even though I think the guy's awesome and has been good in everything I've seen him in, especially Sunshine, he just seems wrong for the part. The key is to really make it feel like an old fashioned adventure movie, like a wartime Indiana Jones. Something about Evans is so...modern. Putting together the images up top helped me actually SEE it, but I still don't know if I'll like the interpretation of the character, or if he'll seem like a man out of time when The Avengers comes out...
It's good to hear that he's enamored with the character above all else, even if he doesn't care much for comics. He said as much at a comic book convention, so he can definitely convince as courageous.
