The Dark Knight Rises’ deleted scene would have enlightened viewers on Bane’s backstory.
According to the film’s costume designer Lindy Hemming, there were a lot of scenes shot by director Christopher Nolan featuring Tom Hardy’s character being critically injured as a young man which might have made audiences feel sympathy for his side.
Hemming has yet to see the movie but told GQ that Bane’s injury not only led him to wear the iconic mask but also his belt and brace.
Hemming said, "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."
After learning from a reporter that what she was describing wasn’t included in the film, she continued, "Well that's an awful shame, but I suppose you have to cut things. I won't elaborate on it too much, because it isn't in the film, but there was another section that showed you why he had the mask and where it came from."
