Yesterday, Marvel kicked off the first in a series of character posters for Avengers: Age of Ultron, with Robert Downey Jr. debuting the Iron Man one-sheet through his Twitter page. Today, it's Mark Ruffalo's turn as he releases the new Hulk poster, featuring the Green Goliath preparing for battle against some of Ultron's robotic soldiers. We'll have to wait and see which of The Avengers will give us the latest one-sheet tomorrow.

In Avengers: Age of Ultron, Tony Stark attempts to jumpstart a dormant peacekeeping program. Things soon 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.

If the Hulk poster wasn't enough for you, Marvel has also released a new TV spot for director Joss Whedon's highly-anticipated Phase Two adventure, arriving in theaters May 1. Take a look at the Hulk poster and the latest footage, and stay tuned for more as the countdown continues.
