It seems there might have been a bit of a big leak from Marvel, with concept art from both Captain America and Thor popping up online. The Captain America pics are over at AICN, who've since had then confirmed by another journalist who visited the production and saw them there (who incidentally revealed there will be two Captain America costumes, one as famed from the comics and another more like a WWII army uniform with an A on it). While these concept pics don't specifically show Chris Evans, they do give us a great idea what the eventual look will be in Joe Johnston's film.
The Thor pics appeared at Collider, and while they're weren't obtained officially, they do seem to be the real deal, especially when you look at the Thor Marvel promo pic of the character released a couple of months ago. If they are legit, it's our first look at the Norse god's glowing hammer Mjolner. Thor hits cinemas May 6th, 2011, while Captain America will arrive July 22nd, 2011. Take a look at the concept art below
