The two minute long trailer showed off the Avengers battling not a villain but rather each other -- a moment that Marvel fans had been clamoring for since Downey was announced as a co-star for the film last year.

The trailer also showed off other Marvel superheros like Black Widow, the Winter Soldier, and the first look at new hero, Black Panther.

The trailer wasn't all the actors presented, however.

Downey and Evans also unveiled the film's first official poster that had the two heroes locked eye to eye within Captain America's iconic red, white and blue shield.
