Continuity mistake: When the boss retrieves the phone from the suitcase, the suitcase between shots if strongly lit all of a sudden. (00:45:20)

Continuity mistake: Joe is having a romantic dinner out with the chemist, at a place where they play nice music (not that she can appreciate that). He ingests some spicy food and fans himself. She is then shown, holding a fork in her right and a spoon in her left, and pausing to look at him in quizzical fashion. Cut to him swallowing some water, and she is still immobile with that look of fascination, but the tools swapped hands and there's a small red fruit in her plate. (00:38:40)

Continuity mistake: During dinner, a waitress brings a pot of food with a burning flame in the middle of it, to one hilarious subdued Cage reaction. During the first part of the scene, the flame burns high with wind blowing to the left during Nicholas Cage's close-ups, and is less intense during the reverse shots on Charlie Yeung. (00:39:05)

Continuity mistake: Joe is talking about the second target with Kong. Kong is eating noodles while Joe triggers the lighter; in the close-up, Kong's hand is at a different angle. (00:32:25)
Sammo
Continuity mistake: Kong makes it back to Joe's hideout after the attempted mugging. He says "But I kicked their asses." Look at the grip he has on the suitcase. Change of angle, and he's holding it differently, with the pinky finger closer to the ring finger and not all spread out. (00:28:00)

Continuity mistake: When Joe shows the wound to the highly inefficient chemist, the fingers are positioned in a different way in the extreme close-up. (00:23:45)
Sammo
Continuity mistake: The protagonist just paid the first 1'500 to Kong. He put the rest away and his arm is still and down his side. But in the next shot ("You come alone, or you don't get paid") he is still rustling in his pocket. (00:11:30)
Sammo
Other mistake: Nicholas Cage travels to Bangkok with a fake Canadian passport - but his last name (he's "Vincent Cadillac") is spelled two different ways on the same document, with one L only at the bottom, which also has the wrong format (lacks "CAN", the code of the issuing countrym in front of the last name).
