Mark Ruffalo on epic ‘Avengers 2’ Hulkbuster battle: ‘It’s a Hulk we’ve never seen’

Call it Mega-Hulk.

“I think it's a moment we've all been dying to see, and getting it right is a big deal,” said “Avengers: Age of Ultron” star Mark Ruffalo of the green guy's epic fight with Iron Man's “Hulkbuster” armor in the upcoming sequel. “There's been a lot of work going into it. I've been shooting motion capture on it for months. And we keep coming back, you know, doing it in little pieces. But it's a Hulk that we've never seen. It's a Hulk on top of a Hulk. It's the Hulk Hulking out.”

In other words: expect a whole lot of Hulk for your money come next May.
