Continuity mistake: As Ducard is sliding down the ice toward the cliff, he's on his front, sliding feet first. Bruce is also on his stomach, but sliding head first. Then, just before Ducard goes over the edge, Bruce is instantly on his back, sliding sideways, right side toward Ducard, just in time to take Ducard's hand, saving him. (00:40:10)
Factual error: In the scene where Bruce Wayne gives a homeless man a wad of cash and trades coats, the wad of cash he had is of the new 20 dollar bill with the big numbers. The new 20 didn't begin circulation until October 9, 2003.
