Re: Why Mark Ruffalo?
And anyways,we werent talking about characterisation (of course it isnt Bixby's Banner in the Avengers - I dont think anyones said that it was) we were talking visually - Ruffalo's Banner strikes a certain chord with some of us older folk who used to watch the TV show and worshipped Bixby. As I said - visually. He's certainly more Bixby than Norton in terms of appearance, and the plaid shirt thing was just a bit of a goof.
Don't be ashamed of the source material when making your adaption. EMBRACE it.
