Go with Catwoman. She's far-and-away the most popular baddie and there are already a slew of searches on possible cast members including Jessica Biel, Amy Adams, and, wait for it, Maggie Gyllenhaal. Do fans think Rachel Dawes, Bruce Wayne's one-and-only, was really the Catwoman all along?
Biel can't act her way out of a paper bag after thrown into the river.
And that fanboy casting of Depp for Riddler? Aint gonna happen. I'm betting $50 invisible bucks on it.
Then again, Catwoman is a good idea. I mean why not for THE CAPED CRUSADER?*
*=$100 says that will be the title for #3.
