The first full trailer for "Captain America: The First Avenger" is here, showing Chris Evans as we've never seen him before: Super scrawny and extremely buff!


Evans plays "Steve Rogers" in the flick, a weak wannabe soldier who joins a top secret project that transforms him into the incredibly fit title superhero.

The movie opens July 22.
