The Avengers provided the best big-screen adaptation of Bruce Banner/Hulk thus far, but he was evenly spaced out with the other Avengers. But when The Hulk was let loose, he was a scene stealer. He was so good that he reignited talk of wanting another stand-alone Hulk film. While Marvel has yet to announce plans to give Hulk his own movie again, he will be getting a beefed up presence in Avengers: Age of Ultron according to Mark Ruffalo.

“[My role’s] even bigger than last time,” says Ruffalo, “and it’s more complex and it has more layers and a bit more arc.” Hulk is so much more than smashing. Hit the jump for more. The film also stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Aaron Taylor-Johnson, Elizabeth Olsen, Paul Bettany, and James Spader. Avengers: Age of Ultron opens May 1, 2015.

Ruffalo also told Total Film that the motion-capture technology has evolved to where he finds it more amenable to his performance for the sequel:

“I’m really tripping on the technology of this motion-capture stuff… now I just completely embrace it and see it as this other exciting place we can go as performers.”

Returning to his comments about giving Hulk a bigger, more complex role, it’s interesting how Whedon is choosing which characters to beef up. We’ve heard that Hawkeye (Renner) and Black Widow (Johansson) are also getting expanded roles, and then there are the introductions of new characters Scarlet Witch (Olsen), Quicksilver (Taylor-Johnson), Vision (Bettany), and Ultron (Spader). It’s possible that by virtue of a sequel expanding on the world every returning actor thinks their role is bigger. It’s also possible that Whedon just wants to play his cards a certain way, and since Hulk and Hawkeye haven’t received any attention in Phase Two thus far, he wants to make sure they’re not forgotten in Age of Ultron.
