I'm going to Nolan hell / Limbo for saying this, but I still don't like the Bane mask here. Nolan's Joker was a spot-on "horrifyingly real life" visualization of the comic character. His Bane though, seems like a character out of a 1990s low budget comic book movie. Designed by someone who didn't understand the visual language of the original character and didn't realize their concept looked goofy.
To me, it's bad enough to be really distracting whenever I see him on screen. Still, he has the voice, the swagger, and the acting chops to make those aspects work. It's too bad he couldn't have also been as visually spot-on as Ledger's Joker.
The attitude Hardy will bring to the role will probably offset that. If the performance is right - and I imagine it very much will be - then after a point you won't even notice the mask anymore. The actions and personality of Bane will be far more visible.
