Mark Ruffalo didn't need much help getting into character as The Hulk in The Avengers.
The actor, 44, looked to his son Keen for inspiration. "I was channeling my 10-year-old son, who I dedicate my performance to," Ruffalo told Access Hollywood at the film's premiere in Hollywood Wednesday. "It's that horrible moment in a child's life when the world expects a certain kind of behavior from them, but they can't quite hold it together and they break out in rage and it's Hulk-like."
Unlike his costars Robert Downey Jr., Chris Evans, Scarlett Johansson, Jeremy Renner, Samuel L. Jackson and Chris Hemsworth, Ruffalo won't be wearing a super hero costume on the big screen. Instead, he donned an "incredibly unflattering" motion capture suit to portray the larger-than-life Marvel Comics character.
"I was wearing a frumpy little, like, linen thrift store suit and they were all in their super hero costumes looking very, very full," Ruffalo told Access Hollywood. "But I think it was exactly how Bruce Banner feels — a little out of place."
The motion capture suit left little to the imagination, Ruffalo added. "It was showing everything and not showing enough — if you know what I mean!"
