Continuity mistake: On lower 5th, the SWAT driver yells lock and load. When he does he has 2 cable ties in loops on his left hand side of his jacket that are exactly equal in size, both the loop and the "tail." We see outside the van for a few seconds. When the camera returns to the driver, the loops are now different sizes as evident by one having a longer "tail". (01:14:00)
Factual error: After escaping the hospital, Harvey Dent wears the same charred suit he was wearing when he was brought to the hospital. That suit would not have been neatly taken off and left intact. It would have been cut off with shears so as not to accidentally remove any damaged skin and flesh when pulling the pants and shirt off. The blazer might still be intact but certainly not the pants and shirt.
Trivia: When Gordon is promoted to Commissioner, Heath Ledger improvised the Joker joining in with the applause.
Question: Just how does Batman's grapple gun work? In Batman Begins, Fox says, 'It's magnetic' so I assume it can attach to anything metal. But the magnet would have to be extremely strong to support the weight of Batman, which begs the question how does it then detach from what he's fired it on? Also, where does he keep all the wire for it, and how does it have the magic ability to wrap its self around the Joker's ankle, when he's been thrown off the building and Batman shoots it at him?

Answer: The gun fires using compressed carbon dioxide as a propellant. The cable is wrapped in a coil around a motorized turbine within the gun. The pulley system in Batman's belt buckle allows him to reel himself in hands-free and still maintain equilibrium. There is a four-pronged grapple at the end of the cable. This is what is magnetized, creating an attraction between it and the monofilament cable. This ensures that the grapple will attach itself to the cable for a secure hold. This is why the magnet itself does not need to be especially strong to support any amount of weight. It also explains the relative ease with which it can be detached and its seemingly "magical" ability to wrap itself around various objects.
