Since seeing Michelle dawn the mask & whip for Batman Returns, there has been a longing for a CATWOMAN based movie. (Wait. There was? Halle who? what are you smokeing?) I think that IF someone came along (Hell even Tim Burton) and didn't a Origin story, that was dark, gritty, and gave the character of Selina Kyle a REASON to become Catwoman (aside from BR), it might actually be success. Some good actors wouldn't hurt either! What are your thought's on how the story could develop?
Personally, I think her "post crisis/year one/Her Sister's Kepper" story line would be a good basis, obviously, it would need to be lifeted a bit so it meets Hollywood standards, but I think it's a good start. I read the script idea for the Pfeiffer spin off few years back. Not the greatest, and a tad bit silly, but better than "that of which we do not speak of"
