emily, the catwoman comment refers to rumors about a new upcoming movie about just catwoman. as far as i know, they're just rumors, and they're hard to believe, considering she's been busy with x2 and a new series based around her bond character, jinx. i think a couple of other projects, too. not sure.
also, there's the fact that "batman: year one" fell through after a promising start, batman vs superman fell through, and no one knows what's going to happen with the next superman movie.
imdb does have a page about the upcoming catwoman movie, which you can find
here, but there isn't all that much info yet, and anything could change.
