What could Tom Hardy Play though? Talia and Catwoman are out of the picture, so what else could it be? Black mask? Hugo Stranges, I've not really hard of these villains except for the TAS animated cartoon show which was solid. Maybe it does have to do with that. My only concern is how they plan to tie the Joker to the whole thing. There will have to be some audio appearance or some connection to the last film given that he "won" against Bat Man in a way.
What about a young Bane? a smaller young pre buff Bane? he may play that, it's essentially a sister role to the Catwoman role.
