Re: Why Mark Ruffalo?
I think the nice thing about Ruffalo WAS how 'disinterested' he came across sometimes. He was detatched, and kept at this sort of mellow tone and pace that seemed exactly how someone would be if they were controlling anger issues. You'd have to become detatched and controlled.
It certainly wouldn't make sense for banner to be really 'interested' and hyper and not controlled.
And everything he said just sort of sounded really mattter of fact, which I liked too. He's past the initial freak out of becoming the Hulk and has accepted his 'curse' and is doing the best he can with it.
He was putting up no false pretenses, not worrying about protecting people's feelings/trying to soften anything.
And I think Ruffalo totally sold that with his delivery.
