During the MTV Movie Awards earlier tonight, Marvel debuted a new clip from Avengers: 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.

Avengers: Age of Ultron is the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

Marvel's Avengers: Age of Ultron stars Robert Downey Jr., who returns as Iron Man, along with Chris Evans as Captain America, Chris Hemsworth as Thor and Mark Ruffalo as The Hulk. Together with Scarlett Johansson as Black Widow and Jeremy Renner as Hawkeye, and with the additional support of Samuel L. Jackson as Nick Fury, Don Cheadle as James Rhodes/War Machine, Cobie Smulders as Agent Maria Hill and Stellan Skarsgård as Erik Selvig, the team must reassemble to defeat James Spader as Ultron, a terrifying technological villain hell-bent on human extinction. Along the way, they confront two mysterious and powerful newcomers, Wanda Maximoff, played by Elizabeth Olsen, and Pietro Maximoff, played by Aaron Taylor-Johnson, and meet an old friend in a new form when Paul Bettany becomes Vision. Take a look at this new scene below, and stay tuned for more as we get ready for Avengers: Age of Ultron arriving in theaters May 1.
