Toward the beginning of the fight scene in building with funeral preparations Jackie climbs a scaffolding. As the people he is fighting push the scaffolding into a wall Jackie jumps to a ledge to avoid getting slammed. The camera angle quickly changes and is looking down on Jackie. If you look at the ledge you can clearly see fingerprints on the ledge next to his hand. These print undoubtedly come for multiple take of the same shot. Jeez just when you thought Jackie Chan is as crazy as he could be, he has to try, try again.
