The Dark Knight Rises, starring Christian Bale and Anne Hathaway, is inviting Steelers fans to a filming of a scene of a football game (between the Gotham Rogues and the Rapid City Monuments) in Pittsburgh August 6 at 7:00 AM. It's not yet clear to me where the taping will be, but it at least sounds possible that it could be at Heinz Field. (And KDKA says that's exactly where it is.)
↵The invitation to extras is (understandably) pretty vague about what the game has to do with the plot of the movie, but strongly implies that something pretty crazy will happen. We could have guessed that anyway - there's no way a Batman movie would have a football game set in a stadium and not have a villain try to do something awful. I bet Bale, at least, will be there.
↵The event is free, and there will be free food and parking. You must be at least 14 to participate, and attendees under 18 must be accompanied by an adult.
