During theMTV Movie Awardsearlier tonight, Marvel debuted a new clip fromAvengers: Age of Ultron, which hits theaters nationwide on May 1. This clip features Tony Stark (Robert Downey Jr.) using his massive Hulkbuster armor as he tries to calm down The Hulk (Mark Ruffalo), after Scarlet Witch (Elizabeth Olsen) “messes with his head.” The result is an epic battle of monstrous proportions as the Hulk and Hulkbuster square off on a crowded street.
