Continuity mistake: When Jack Burton and the rest of the gang escape from the Wing Kong Trade Centre the first time, the guards fire at the left side of the bus breaking the windows and making holes in the bodywork. When we see the bus a few seconds later as it is driving away, it appears undamaged.tw_stuart
Continuity mistake: Toward the end of the film, when the creature captures Gracie, he jumps through a hole in the floor with her on his back. As he falls through the hole, his feet fall out in front of him and he is shown almost prone. Yet when the shot changes he lands firmly on his feet.Jason Hoffman
Revealing mistake: When Egg Shen helps the others escape by using a crossbow-and-winch device, he fires the bolt into a stone. When the bolt digs in, the stone shudders slightly (since its made of wood or plastic, and no fixed part of the floor).
Revealing mistake: When Lightning makes his appearance in the street fight scene, at the point where his 'lightning rod' impacts, we can see a badly covered explosive charge and ignition cable on the asphalt.
Other mistake: After Jack climbs up the ladder and through the floor he then runs right to the locked door, all this takes about ten seconds. Somehow in those few seconds Wang, Gracie, and the rest of the girls have all made it up the same ladder and coming around the corner when he gives him the signal to come to the door when there's no way they couldn't have all done it that quickly.jbrbbt
Other mistake: Early in the film, Jack says Lopan had "light coming out of his mouth" but Jack was already blinded and couldn't have seen that.
