Continuity mistake: In the big fight seen in the museum Jackie is holding up a large vase while 2 bad guys are punching him. Jackie sees one of those pole things that hold the velvet ropes and wraps his leg around it. When he does you can clearly see that the the pole is right side up, then when he kicks his leg up to hit the bad guy in the face is it upside down. (01:19:15)

Continuity mistake: When Lee and Carter are chasing Sang onto the broken bridge in the run down building, Sang trips and drops the detonator, which then falls towards the edge of the bridge.
