I am just mad about this, apart from him already being a marvel character, which he did quite well, Captain America is completey different to Torch, ridiculous casting there...
Cast Billie Piper as Peggy Carter and watch the sparks fly!
In all seriousness I was a bit unsure of the other Chris Evans as Cap, but he was brilliant as Johnny Storm (one of the best things in either FF movie actually), and he looks good in The Losers, so I'm willing to give him a go as Cap if he bulks up a bit. I thought for sure they would cast the guy from Avatar/Clash Of The Titans, but as he's not American there would probably be riots for casting Captain AMERICA as anything other than a yank.
They could dub his voice, like they allegedly did to Sam J Jones for Flash Gordon. I think Evans could look the part, although Matt Salinger's left pretty big boots to fill...
I'd cast the whole cast of Allo Allo! "Good moaning Captain America, I was just pissing by and I couldn't 'elp noticing your bog rund sheeld".
Not many big actors will do most of a film under so much prosthetics but Weaving proved himself in V For Vendetta that he doesn't need to show his face to be a great actor.
