Re: Why Mark Ruffalo?
Ruffalo was brilliant in this movie. A very subtle, nuanced performance. He wasn't uninterested, he was intentionally playing the character as aloof and withdrawn. But there was a few moments where you could see a playful glint in his eye. He wasn't playing Banner as a depressing saddo. He was playing him as a man who had come to accept the other guy and was constantly keeping him in check throughout the entire movie.
