facts from the teaser trailer...
-Commissioner Gordon is the one in the bed in the trailer
-Commissioner Gordon is talking to what most people agree is Bruce in a balaclava, although there is some dissent about that. But either way, it's Bruce.
-The most common theory about the guy doing push-ups is it's Bruce in a flashback to his League of Shadows training.
-No one knows if Bane uses Venom for sure, but the most common theory is that he uses it in some form and inhales it through his mask which, incidentally, is why it's so big and clunky.
-No one knows whether Bane breaks Batman's back.
-No one knows who Joseph Gordon-Levitt's character is, or his significance.
-No one knows who that person in green pants in the final scene of the trailer is, or what they're doing there.
-The guy climbing up the well is either Bruce or Bane, I personally lean towards Bane but no one's quite sure, and what he's climbing up looks to be the well from Wayne Manor but, once again, no one knows.
-Nobody knows what that weird chanting is or what it means, but it's a good bet it's just part of the soundtrack and doesn't mean *beep*
-Nobody knows ANYTHING about Catwoman other than who's playing her. Not her costume, not how big her role is, not what side she's on, nothing.
-The movie doesn't come out for a year
-There's been like half a minute of footage and almost zero information about the film released. If you don't know the answer to something, it's a good bet nobody else does either.
