But I could see Scarlett, as long as the part doesn't call for her singing any Tom Waits songs.

EDIT: Woah. Just had a thought. You know who could pull off Catwoman? Chloë Sevigny. She's hot (or at least, she can do hot), and she's WAY edgy. She can play girlish and playful, she can play crazed psycho, she can play seductress. She's CLEARLY got the acting chops for the part, I think. And she's method just like Nolan and Bale.
