Mark Ruffalo Promises 'More Science Bros' in 'Avengers: Age of Ultron'

As he continues making press rounds for his new film Begin Again, actor Mark Ruffalo keeps spilling the beans about what fans can expect from his next turn as the Incredible Hulk in The Avengers: Age of Ultron.

During a career retrospective with Total Film, Ruffalo offered some predictions about the upcoming Avengers sequel, once again written and directed by Joss Whedon. He makes one pledge that's sure to send squeals of delight into the deepest depths of Tumblr: The Jade Giant and Ol' Shellhead will have even more fun stuff to do together.

"There's more stuff with Banner and Tony Stark," Ruffalo said with a grin. "More Science Bros stuff."

The "Science Bros stuff" was easily one of the highlights of the first Avengers film, so much so that Ruffalo's sleepy Banner was right at the heart of the Iron Man 3 narrative and post-credits stinger. It's not a surprise to hear that Banner and Stark will have even more to do together this time around, but it's certainly a welcome tease at the very least.

Beyond Banner and Stark, Ruffalo said that Age of Ultron expands what we know and love about Earth's Mightiest Heroes, while bringing an amazing new nemesis into the fold as well.

"It's pretty sweeping. It's pretty epic," he said. "It's, oddly enough, a much bigger movie than Avengers 1 was. It's a little big darker. We get a lot deeper into the characters now since we established them in the first one and can cover a lot more ground. Ultron's incredible."

The Avengers: Age of Ultron arrives May 1, 2015.
