The backstory of Tom Hardy's masked villain was partially explained in Christopher Nolan's film, but costume designer Lindy Hemming told GQ that a cut scene would have gone into more detail.
Specifically, the scene in question showed Bane being critically injured as a young man, and later being taunted by his peers for his disability.
"The thing that you should have seen during that sequence is [Bane] being injured in his youth," Hemming said. "So one of the fundamental things about his costume is that he has this scar from the back injury."
She later continued: "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."
