The first full trailer of this summer’s upcoming Captain America film, The First Avenger, was released today. In case you weren’t prepared (which I’m thinking most of you are), there’s a windfall of Marvel superhero movies all coming out to set up the inevitable Avengers mega-blockbuster, and along with Thor this summer will belong to Captain America. Will these releases be among the stellar crop of comic book films (X-Men 1 & 2, Iron Man, 300, Watchmen, etc), or will they just be disposable origin stories to set up the Avengers flick? I guess we’ll see…
