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.
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.
Suggested correction: It was a long enough drop for the beast to adjust itself to land on its feet.
Continuity mistake: When Jack runs Lo Pan over with the truck, he signals Jack to drive towards him. A shot later when the truck hits him, his hand is lowered.
Suggested correction: Between the robe LoPan wears and angle of the camera, it can't be determined if his hand is lowered, or in the same position.
You can tell the hand is lowered because his hand should be visible as it was above his shoulder. And to point out the obvious, when it cuts to the front of the truck, it's a dummy in place, so we know his hand isn't up. We also see the dummy fall over as it's hit making it more obvious the hand isn't raised.
Continuity mistake: During the escape from Wing Kong Trading, Jack climbs up from the sewer to figure out the escape route. He runs to the door and almost immediately behind him, everyone has managed to climb up from the sewer much faster than would be possible.
Continuity mistake: During the escape from Wing Kong Trading, they all jump into a pool and swim through a pipe which is not big enough for people to pass each other. Despite the fact that Margo and Jack are in the water before Gracie, she manages to come up for air before both of them.
Continuity mistake: While driving, Jack holds Miao's picture. In the close-up his fingers disappear.
Continuity mistake: When Wang is playing cards, the position and movement of his hands is not continuous between shots. (00:05:44)
Continuity mistake: The bed the girl is tied to has six posts by her head, her hands are tied to the second and fifth posts, switch to the third and fourth posts when Lightning enters the room and go back to the second and fifth posts when he cuts her free.
Continuity mistake: When Lo Pan is questioning Jack & Wang while they are in the wheelchairs, the security monitors on the wall change from 2 to 4 then back to 2 again.
Suggested correction: We are seeing 2 different sets of monitors. When Lo-Pan first comes in, he is next to the 2 monitor set. You can tell that Jack and Wang are looking to their right. Then, Lo Pan moves closer, right in front of them. After a little conversation, Lo Pan backs up straight, still in front of Jack and Wang, to a different set of monitors, with 4 screens. He then leaves, out the same door he came in, to Jack and Wang's right, passing the 2 monitor set on his way out. The monitors stay consistent.
Continuity mistake: When Gracie and Jack are talking in the sewer tube, she lifts her foot up and you can see she is barefoot when she is wearing boots both before jumping in the water and when she gets out.
Continuity mistake: When the flying soldiers appear, there's a wide shot and Jack and Wang disappear from inside the truck.
Continuity mistake: Jack asks "is this going to get ugly now?" and extends his arms. From the opposite angle they're lowered. (00:07:01)
