Knowing Nolan, he could possibly make a cameo, but I'm not sure he'll have full development as a villain. In order to open a scenario where he appears again, someone from Falcone/Maroni's circle needs to hire him in order to have their own manhunt for Batman. I believe Nolan will in the third movie address the organized crime element more in the third movie in addition to villains who are looking to cause as much chaos as the Joker. We'll see.
I've been reading the DC forums a lot and the consenus seems to be that the major of gotham hires an assassain (Deadshot) to take care of Batman, now that Batman is known as a cop killer. I think they could definately make that work.
Also Daniel Day Lewis I think could do the Joker without missing a beat. It would be awesome to have Harley Quinn and the Joker cause of their crazy relationship
I'd love to see Two-face return from the possible dead in the next movie along with Bane. I usually hate having two villains in a superhero movie but Begins and the Dark Knight made it work. Besides Bane is a god damn badass and the only villain to snap Batman in half like a twig.
why does no one want victor freeze him and joker are the best villains in the batman saga!
Why would you not want to see this in real life....
or this...
Okay, I'm not actually making a vote here, but come on. The history of the villans of Batman are almost the same. Normal person, tragic accident, goes mad, becomes a villan.
