Here's a casting rumor that might be a little controversial...
I'm honestly not sure how I'd feel about that. On one hand, he's a very good actor with the kind of presence that would make people follow him, both in the movie and to the box office (Of course, I can't imagine them signing him for a 3 picture deal, plus the Avengers movie). On the other hand, he's black. Personally, I don't know if Cap's image is so iconic that there needs to be a certain type of actor to play him, but I can imagine a lot of fanboys blanching because of this. Of course, the same could be said with a very gay man playing the role, too (John Barrowman).
Is Cap's history tied in with what race he is?
