Mark Ruffalo as The Hulk

So earlier this month, Edward Norton gracefully admitted that he would not be reprising his role as Bruce Banner, or better known as, "The Hulk," in the upcoming movie, The Avengers. Over the weekend it was announced that Mark Ruffalo, star of Eternal Sunshine and The Spotless Mind, 13 Going on 30, Shutter Island, and most recently The Kids are All Right, was going to take over. A similar situation happened for Jon Favreau (the producer of The Avengers) when he had to replace Terrance Howard with Don Cheadle in Iron Man 2. Director Joss Wheadon, sounded off about the casting choice of Mark Ruffalo,

"I'm stunned that we landed that, just stunned. He has what I remember loving about the show, that quality of, you just look at him and you go through it with him, he invites you in in a way that [no] other performer has since Bill Bixby. He is a guy who's been beaten up by life, but not defined by that. That’s what I want from Bruce Banner, is a guy who’s still getting it done, even though he has his problem."

While there is no way to argue with the fact that Ruffalo is a fantastic actor, The Incredible Hulk is not exactly similar to the rest of his resume. I don't exactly have doubts, but I am anticipant to see what he does with the part.
