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.
Revealing mistake: After Lo Pan jumps over the truck, the dead soldier on the ground is replaced by a very obvious doll.
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)
Revealing mistake: During the gang fight, whenever there's a close-up of someone falling on the road it wobbles and bounces giving away it's a rubber mattress. More evident after a guy is launched through a window and another is crushed against the road. (00:19:43)
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)
