A website called Nuke The Fridge, which I believe was established by guys who were kicked out of the Ain't It Cool talkbacks, is running a rumor that the Blu of The Dark Knight Rises will be a director's cut, and will contain deleted scenes that include an expanded origin for Bane. As proof they use this quote from Lindy Hemming in GQ:
“The thing that you should have seen during that sequence is [Bane] being injured in his youth. So one of the fundamental things about his costume is that he has this scar from the back injury. Even if he hasn’t got the bulletproof vest on, he still has to wear the waist belt and the braces. In that scene in the prison, where he’s learning to fight the same way Batman learned to fight, he’s wearing an early version of his waist belt. It’s showing support, but it’s not the finished one he eventually wears. He’s also wearing an early version of his gas mask, all glued together.
If you look at the film, unless they’ve cut it—and I’m sure they haven’t—there’s a whole early section for Tom Hardy where he’s fighting and being taunted by people. He’s got chains on him, and he’s standing on a wooden thing while people are attacking him. And in that scene, he’s wearing a much more ragged, primitive version of the mask.”
The thing is they did cut it. And judging by the film, that isn't all they cut. But one would argue that the film we see is Nolan's director's cut, right?
Maybe. Kind of. There's an interesting technical aspect to this all: The Dark Knight Rises runs 165 minutes, which is also the maximum length for a movie to fit on one IMAX platter. So Nolan had to make the film that length to take advantage of his love of IMAX. Which could mean that he was forced to trim things for purely technical reasons - things he could be interested in re-inserting in the home video release.
My understanding is that Nolan has never done a 'director's cut,' but the circumstances here make it seem plausible, especially if NTF's sources - who claim there is a half hour of deleted material being put back in - are correct.
