Mark Ruffalo recently commented on his role as Bruce Banner and the Hulk in The Avengers 2.
Ruffalo tells Total Film that this time up, he has a bigger role.
"[My role's] even bigger than last time, and it's more complex and it has more layers and a bit more arc."
"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."
Mark Ruffalo previously posted the following image of himself wearing a motion-capture mask for the part of the Hulk.
It's also speculated that The Avengers 2 might open with a Hulk vs Hulbuster Iron Man scene, which concept art and comments from a rep from South Africa seem to suggest.
"The Avengers: Age Of Ultron" hits May 1, 2015 directed by Joss Whedon starring Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Mark Ruffalo, Jeremy Renner, Samuel L. Jackson, Elizabeth Olsen as Scarlet Witch, Aaron Taylor-Johnson as Quicksilver, Paul Bettany as Vision, with James Spader as Ultron.
