Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Plot hole: Sarah breaks a mirror in frustration by throwing something against it. Then she buries her face in her arms and sobs. It remains a mystery how she managed to cut her hand so bad that it needed to be fixed with five stitches, as she isn't even seen picking up the pieces. (00:59:15)NancyFelix
Continuity mistake: During Kevin Bacon's race with fellow messenger, the scenes shift back and forth from New York to San Francisco. In one city, he's on a fixed gear (no freewheel on back wheel) and when the race is taking place in the other city, he's riding a single-speed. Basically, the cityscape and bicycles switch from scene to scene.
Continuity mistake: In the opening scene the camera pulls back from a bedside locker to an over the shoulder shot of Kathleen Turner's character doing her make up in the mirror. Close inspection shows that the shoulder in the foreground is actually that of a double who doesn't quite match Turner's movements.
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: When Max has the accident with the bus, it is only a minor fender-bender. In a later scene, his car is shown in a junk yard with much more damage to it than what was originally done.
Continuity mistake: In the scene where Remy finally figures out that Ann has some serious questions about his dept., he pushes her against a tree. When the camera is on him, her necklace has swung around to the back of her dress. When the camera is on her, the necklace is 1/2 inside and 1/2 outside the front of her dress. This switches back and forth several times.
