they'd have to get a new Batman I bet
Yeah. And Superman. Nolan said both franchises as long as he is overseeing them will never co-exist in the same universe. I mean WB could do it after he is bored with the franchises but they'd have to recast and all of that (Bale, Oldman, etc all say they wont do the movies without Nolan) and it'd be far easier to just reboot it. Plus trying to use Nolans worlds would likely piss off Nolan quite a bit and WB wants to keep Nolan in house.
I suspect both Batman and Superman we be rebooted after Nolan gets his hands off of them to be more..comic booky in line with the more light hearted looking Green Lantern.
so will Avengers
I agree. Waaaay too over-stuffed with characters and Whedon is in far over his head.
Green Lantern will bomb.
Is there anything you think won't fail?
