I don't know about Halle Berry playing Catwoman beyond rumors. I know Ashely Judd had the role for awhile, but I think she's not attached anymore.

Whoops, I take that back. Checking Superherohype, there's an realvideo bit of Halle from "E! Real News Live" that apparently says that "she will be starting Catwoman in September, after she's done with 'Gothika'". Guess she's kinda busy.

"You need me. You wouldn't be much of a hero without a villain. And you do love being the hero, don't you. The cheering children, the swooning women, you love it so much, it's made you my most reliable accomplice." -- Lex Luthor to Superman, Question Authority, Justice League Unlimited
