The character posters keep coming for 'Captain America: The First Avenger,' with the latest featuring a helmetless Chris Evans as the superhuman superhero against an American flag backdrop.

The second trailer for the film, which opens July 22, continues the recent Marvel tradition of scoring superhero punches to metal bands. Sure, Iron Man and Black Sabbath were a natural combo, now it's Captain America and Tool. Sadly, unless there's a fanvid out there, Thor never swung his hammer to the strains of Led Zeppelin's Viking-tastic 'Immigrant Song.' (Though we love the Trent Reznor and Karen O cover for 'The Girl With the Dragon Tattoo.')

The All-American poster and Tool-heavy trailer are after the jump.
