Christian Bale, Aaron Eckhart, Gary Oldman, Christopher Nolan, Jonah Nolan and David Goyer all showed up this weekend at the Wizard World Chicago convention to talk about production of the "Batman Begins" sequel and more importantly - show off the first footage.

According to some attendees, what was shown included: Bruce Wayne and Harvey Dent meeting for the first time, Rachel almost embracing and locked together with someone, the Batsuit rising up from a trapdoor, a spinning 50 cent piece, The Batmobile & The Batpod racing through the streets, Gordon (in SWAT gear) booking the Joker and saying he has no identification (incl. fingerprints, ID, clothing tags, etc.).

There were also several shots of Heath Ledger as The Joker including one in a prison cell his face covered in blood, another in the same cell where Batman beats him up, him firing a machine gun, and him laughing hysterically during a TV broadcast. Finally came the money shot - Harvey Dent seen from behind his left shoulder (some mild neck scarring visible) and someone asks "Dent? I thought you were dead?" to which he responds tersely - "Half."

A more detailed description can be found at Wizard Universe. There is also a full transcript of the Q&A session that preceeded the footage.
