So whats next for The Dark Knight?

So the tallies are in (and by tallies I mean the shit load of cash) and The Dark Knight is hands down the greatest superhero film of all time. Not only wasn't it enough that the franchise brought home half a billion in the United States and over a billion world wide but with the film just releasing to dvd this past Tuesday The Dark Knight broke records in both blu-ray and dvd sales. Now with The Dark Knight getting some nods from the Golden Globes and the score of the film officially being nominated for an Oscar the question is what's next? How can Warner Brothers, DC, Chris Nolan, and David Goyer top a film that just barely fell short of beating Titanic for the highest grossing movie of all time?

So far the rumors have it that this Feb. 2009 WB wants to reopen the Batman Begins office and get the film underway for a possible Fall 2010 or Spring 2011 release and the rumor mills are on overdrive with speculation of which villains will be in the third, and some say, final film of the new franchise. As it stands right now Christian Bale will be returning as the Caped Crusader, Michael Caine will be back as Alfred Pennyworth, Morgan Freeman will return as Lucius Fox, and Gary Oldman will be back on as Commissioner James Gordon. The third film has been rumored to be called Shadow of the Bat or The Dark Knight: Shadow of the Bat. People are already speculating that Johnny Depp has interests in playing a more realistic Riddler which will be a departure from Jim Carrey's entertaining yet over the top Riddler in Batman Forever. Also a so called WB insider said Angelina Jolie has been contacted on several occasions for a possible Catwomen role. Now these are all ofcoarse rumors and the only thing Nolan has said about the third film is that he thinks the Penguin would be too hard to portray realistically and as long as he was the director there would be no Robin.

So, as the Batman faithful, who would you like to see? What supervillains from Gotham have you always wanted to see portrayed in a realistic light and what actors would you pair them up with?
