To be fair, she was cast as Selena Kyle. It's possible that "catwoman" won't have a major role.
Yeah, that's my take as well, although I think Catwoman will be a recurring motif (news reports of a female cat burglar, Batman spotting Catwoman while working on another case, but ignoring her, losing her in a chase, etc.) throughout the film. Just guesswork, but I think Catwoman will appear toward the end, with some sort of love triangle between Bruce/Selina/whoever falling apart at the end once Bruce sees that Selina is Catwoman.
