Marvel Studios (via the SuperHeroHype Forums and Reddit) have revealed new promo art for their summer release Avengers: Age of Ultron, which includes more Hulkbuster action, more Ultron being his big bad self, Thor in a very Frazetta-era Conan pose standing atop a mountain of robot skulls, Black Widow and profiles featuring the origins of Vision and Ultron. Check out these glimpses of coolness below!

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.

Avengers: Age of Ultron stars Robert Downey Jr., Chris Hemsworth, Mark Ruffalo, Chris Evans, Scarlett Johansson, Jeremy Renner, Samuel L. Jackson, Aaron Taylor-Johnson, Elizabeth Olsen, James Spader, Cobie Smulders, Thomas Kretschmann, Paul Bettany and Stellan Skarsgard. The Joss Whedon-directed film will debut in theaters on May 1, 2015.
