Aaron Eckhart is probably pulling our leg about Angelina Jolie, too. And really.... I would lose a little faith in Mr. Nolan if he got Cher to play Catwoman. Seriously.

I am kind of upset that Harvey/Two-Face is REALLY dead though. I would've liked to see him come back as he was an excellent villian
(*SPOILER HERE*) [bgcolor=#000000]That scene at the end when he has Gordon's kids and was like "Tell your boy it's going to be okay. LIE!" made me almost cry both times I saw it because I was so freaked out.[/bgcolor] But I'll say it again, Riddler would be the best choice for the next one. Catwoman is one of my absolute favorite comic characters of ALL TIME.... but as far as being a real threat and pushing an entire movie forward... not so much. She's only a cat burglar and while they could play with the whole Batman/Catwoman relationship, I just don't seeing lasting for a whole epic movie. Perhaps they will throw both villians in. It'd be a very interesting mix (better than Penguin and Catwoman which I am absolutely sick of. It's all over the cartoons, too).
I also can't really think of anymore pretty realistic villians that would work in a Nolan Batman film. Maybe Clayface, but not really. The only other one I'd like to see is Hush... but we're not that far in to Batman's life. Haha.
