I think there must still be some major portions of the movie that we still don't have a clue about.
First, based on widely held beliefs (and the sides for casting), there are 3 female roles - WW, Talia, and Iris. Since Palmer was seen in Australia at the hotel, and Kazan confirmed first-hand to Moviehole about being Iris, that means that there is either a role that we don't know about for either Palmer or Green (meaning Green might be Talia and Palmer is someone else, or Palmer is Talia and Green auditioned for someone else), or Gale isn't WW like we thought.
One of the reasons I think there might be another role that we didn't know about is because for the sides that were posted for JLA casting, there were 3 female options and 5 male options. But in the movie, there is going to be Supes, Bats, Green Lantern, 2 Flashes, Aquaman, MM, and Max Lord. That's 8 guys. And even if MM is CGI, that's still 7.
So . . . any thoughts as to what I'm missing?
