"I dropped a bomb. I was talking with Chris Nolan and said, ‘I have a voice for Bane.’ He said, ‘Okay.’ I said, ‘It’s based on something I saw on YouTube.’ He said, ‘Okay.’ I said, ‘It’s the voice of a Romany bare-knuckle fighter named Bartley Gorman.’ He said, ‘Okay.’ And then I did the voice."
He never had to try anything else. “At first, I responded with a great deal of trepidation, because like everything else that comes from Tom, it’s off the beaten track,” says Christopher Nolan. “Then I became massively excited, because when you work with a great actor—and Tom is one of the greatest—you start to understand that they’ve found something. It just becomes part of the character. It’s something that you’re never going to be able to take away from the character. It’s not really a matter of having an opinion about it—it just is. Okay, that’s Bane.”
