Continuity mistake: Scene with the new store manager and love interest; Tuba pantomimes 'testing the water in the shower'. He puts his hands in his pocket when he realises that someone is glaring; that's in the first shot, because his hand is frozen in mid-air in the next shot instead. (00:18:10)
Continuity mistake: When the assignment officer puts the papers inside Cheung's holster, he reaches for the holster (and grabs it) twice. (00:14:50)
Continuity mistake: As Tuba's story about the folk-dancing at the funeral becomes exponentially more ridiculous, the man in the pink shirt tries to convince his wife, but there's a clear lack of continuity in his movements between the various cuts. (00:11:15)
Continuity mistake: When Tuba's poor friend protests because his pretend-folk-dancing has been overlooked, the pretend-fisherman is suddenly fishing with his chopsticks in his bowl, while he was not doing anything a moment earlier. (00:10:50)
Continuity mistake: When Tuba's friend drops the strainer to have a quick exchange under the table, the strainer falls next to the table's leg, but the unattractive girl picks it up from Tuba's left (the leg is at his right). (00:09:20)
Continuity mistake: When the van crashes into the stage at the marathon, the crash happens in two separate takes, as you can see by the position of the guy in a light blue jacket, who dodges the incoming vehicle with radically different timing in the two shots. (00:03:20)
Continuity mistake: In the wild stun where Rambo Chow jumps through the cracked windshield into the moving van, in the first take the stuntman doesn't quite land right into the windshield (in fact he hits the frame in a way that could possibly break a hip) and his body bends awkwardly, but in the next shot you see him slide in smoothly. (00:03:15)
Continuity mistake: David Chiang chases the man in a purple dress at the 1985 Hong Kong Marathon. He fires a warning gunshot; if you look at the guy in the back of the pick-up that the criminal is about to hijack, he lets go off the bar twice in two different shots. (00:02:35)
