What about Megan Fox as the Cat Woman? ;)
Catwoman has been destroyed for all time by the movie of the same name. I believe they said it will not be the Riddler.
I’d like to see the Riddler, but my money is one Cat Woman.
She’s certainly got the look. Catwoman has never been among my favorite Batman villains, though. I think a Zodiac-style serial killer as the Riddler, and a mob-boss Penguin might fit better in Chris Nolan’s pseudo-realistic universe than Catwoman.
Catwoman, Mr. Freeze, Bane, Poison Ivy, etc. might be more difficult to write realistically ... though I wouldn’t mind seeing what Nolan could do with Freeze. Clayface, Man-Bat and the Killer Croc would be almost impossible to fit in Nolan’s re-imagining.
The real questions are (1) will Harvey Dent be back and (2) will the Joker make an appearance? Two-Face didn’t get much screen time ... and they didn’t explicitly kill Dent off at the end of TDK (though it was implied).
As for the Joker ... I wonder if we might get an homage of some sort from inside Arkham. Maybe just from the back, a laugh, a shadowy face, or even an appearance with Ledger’s face CGed (ala Schwarzennegger in Terminator Salvation).
