Could Mark Ruffalo play Hulk in 'Avengers'?

Lots of big players in Hollywood can act like children at times, as seen recently via the bid Edward Norton dispute and the question of whether he'll play Bruce Banner aka. the Hulk in "The Avengers."

Well, it's pretty clear now that Norton will not be the Hulk, and that brings up the question: who the heck will replace him? Considering Marvel is trying to turn "Avengers" into a big movie, it's a crucial decision.

Deadline Hollywood has one lead, reporting that Mark Ruffalo is a hot contender for the role. The site says he has an offer on the table, although other sources attached to the film say nothing is a done deal.

Ruffalo is an interesting pick. He's without doubt a fabulous actor, but I admit I was surprised when I heard his name pop up for this. Could he do it? I think he'd totally deserve a shot at it. Don't you think?
