The new trailer premiered at Yahoo Movies, and features quite a bit of new footage from the film — including some impressive shield-slinging action!
About half of the new trailer focuses on scenes from Steve Rogers' life prior to the super-soldier serum, including a great sequence involving Tommy Lee Jones and a fake grenade.

We also get a look at a few iterations of Steve's costume and shield, as well as some new footage of Hugo Weaving as Red Skull. Oh, and the Howling Commandos make an appearance, too — which is always an extra dose of awesome.
"Captain America: The First Avenger" is scheduled to hit theaters July 22. Keep it locked to MTV Splash Page for more "Captain America" movie news as it develops!
