When the subject of multipicture deals came up during an interview with Collider.com, the Avengers actor revealed he's set to play Bruce Banner and his alter ego a few more times.
So exactly how many flicks did Ruffalo sign on for?
"Six," Ruffalo said.
But despite the lengthy commitment to Marvel, the 44-year-old star clearly doesn't have a problem with it.
"The experience was great," he said about making The Avengers. "I really had a good time. It was fun, and I love that group of people."
That's a good thing, of course. Because you definitely don't want to make him angry.
