6 Reasons Why Tom Hardy's Bane Was So Perfect
#4 He Based Bane's Voice On a Bare Knuckle Boxer
Nolan kept some elements of the comic book version of Bane, but still made unique changes of his own. For instance, instead of sticking to the commonly known story of Bane gaining strength from tubes that pump a powerful steroid called "venom" into his blood, Bane was given a mask with a more realistic and scientific purpose. These changes were important to how Tom Hardy would make Bane's voice. Also, Bane's voice was one of the very few resources Hardy could use to make the performance memorable so it had to be good.
In the comics, Bane had a Latin American background. On the the big screen, Bane had an undeterminable origin. On the one hand, this worked just fine since Bane's backstory has changed as much as the Joker’s backstory over the years. On the other hand, Tom needed a voice that touched on the history of the character without coming off like a Mexican wrestler as so many versions of Bane often have. Hardy took inspiration from Bartley Gorman, a bare-knuckle boxing champion. Contrary to critical nerd reviews, this was not really a betrayal of Bane’s origins. Gorman was a Romani gypsy. Even though it wasn’t the expected Latino accent, it is still Latin. In Hardy’s words, it was "underpinning the traditional Latin origins."
