I always love how people jump to conclusions about this kind of stuff. Everybody always makes a big deal out of it when the do reshoots for a movie like this, but I was under the impression that it was fairly common practice, even when they're aren't major problems.
I think the "problem" is that in this world of everything
being reported on the Internet, people see reports of reshoots and think the worst because before reshoots wouldn't have been reported. As such, people may not think of reshoots being common practice.
Personally, I cannot wait until we hear about any reshoots for TDKR, because the fanboys will go crazy. "Whut?! RESHOOTS? What the fuck, Nolan?!?! I hope its for Bane's voice."
