I'd really like to know the definitive answer on Jinx. Is she a villain or not? First, by Halle Berry's admission, she was. Then at the press conference she wasn't. Then she was again a villain. And now she's not.
That's according to the IMDb, who have reported Berry as saying that Jinx isn't a villain but "When you see the movie you'll see. She's a multi-layered character".
