Re: Why Mark Ruffalo?
If Ruffalo plays the role for a long time (and is currently the most universally praised), then he could hardly be considered the equivalent of George Lazenby (since Lazenby walked after 1 performance as Bond but some have mistakenly thought he was fired) and Norton can hardly be thought of as the Connery of Banners.
Although he's not a cinematic Banner, I count Bill Bixby as the Connery of the live action Banners.
