Continuity mistake: Joanne's dad hits Tuba up with the baseball bat after he tried to fix his zipper; between shots Sammo Hung's hand is in a different position, as you can tell by the writing on the bat that suddenly in the second shot is in view and not covered by the hand anymore, and even further uncovered in the next. (01:29:15)
Continuity mistake: Jeong-lee Hwang is fighting Tuba in front of a metal cage. He sends him against several boxes of fruit, and you can see Sammo Hung reeling against a brown box of apples. Out of nowhere, in the next shot a box of oranges appeared on top of it. (01:20:40)
Continuity mistake: Ghost Rambo eats the apple, then puts it quickly back on the plate. The apple is lying on the side in close-up, but when Tuba looks around puzzled, it is sitting on the plate with the stalk up. (00:55:00)
Continuity mistake: Tuba jumps out of the supermarket in joy after asking Joanne out. The people around him when he leaps are different from the ones around him when he lands; in particular you can notice behind him in the second shot there's a lady with frizzly hair and a white sweater that already sped way past him in the first one. (00:52:30)
Continuity mistake: After the successful capture of the two crazy butchers, Tuba and Cheung are in their boss' office. During the earlier part of the scene, the left hand of the boss goes from above to below the table as the camera angle switches to the reverse, and vice versa. (00:43:15)
Continuity mistake: When the bad guys bring the suitcase, the one wearing gloves does not finish opening his end. However, in close-up his hand while being at the same spot rests on a suitcase already fully unzipped. (00:32:45)
Continuity mistake: In the gag of the photo on the pier, the guy taking the shots at first is wearing his scarf with one end dangling in front of his chest (when he asks the model to be more feminine), but immediately later the scarf runs behind his back. (00:24:55)
Continuity mistake: Tuba is approached on the pier by a bad guy, or at least one guy with a really nasty 'stache. The guy puts his hands on his hips, and they are at a different height depending on the camera angle. (00:23:40)
Continuity mistake: Rambo makes his nosy colleague put a headset on and pumps the music. In the scene, Rambo is holding the Walkman in opposite directions in close-ups and the normal angle, as you can tell by the side the headphones are plugged in. (00:22:30)
Continuity mistake: Police station, Cheung walks into the room where they play the extortion tape. The officer's hat changes position facing a different direction on the table between shots. (00:16:00)
Continuity mistake: When the secretary hands to the chairman of "Bel Fuse Limited" the phone, her hand is in a different spot of the receiver in the two shots. (00:15:30)
Continuity mistake: After interrupting (sadly not for good) Sammo's date with the ugly girl, his roomie at the station, Cheung, gives the assignment officer his papers. The officer in the second shot has in the other hand a second set of papers he didn't have a moment before. (00:14:00)
Continuity mistake: Tuba's coworkers try to hook him up with a lanky chick not of his liking. When she tries to flirt with him carrying a fish head on a plate, the head does a 180° between shots. (00:07:55)
Continuity mistake: At the convenience store, Tuba jumpscares the girl he's trying to flirt with. She turns back to the clients; between shots, the bottles of Sprite and Fanta swap position. (00:05:20)
Continuity mistake: Rambo wakes Tuba up spilling the cup's content on his face, but the liquid almost completely vanished when it cuts back to Sammo Hung's face. (00:56:00)
Continuity mistake: When the policewoman slaps Tuba for dilly-dallying during her rape, Sammo puts his hand on his cheek. In the reverse shot you can see he moves the hand away, but it's back where it was when we go back to the original camera angle. (00:48:50)
Continuity mistake: To go to the place where he has to deliver the blackmail money, Sammo jumps on a taxi with a large round sticker on the back passenger window, and gets off a taxi without such sticker. (00:26:30)
Continuity mistake: In the gag where Joanne asks Tuba where does he live, two ladies (could be mother and daughter age-wise, the younger one wears a black and yellow vest) are walking out of frame behind Joey Wang towards Sammo Hung, but they do not show up in the matching reverse shot, only in a later shot. (00:20:45)
Continuity mistake: Under the stern watchful eye of the new female store manager, Sammo picks up a box of cereals. He looks at the gap he created on the shelf, and sees her. Notice that both boxes of Frosties at the side of the gap are facing him, but in the reverse shot, one box faces in, the other faces out. (00:18:20)
Continuity mistake: In the comedy scene in the kitchen, Sammo Hung crushes eggs getting yolk all over his apron. When he actually crushes them, the yolk spills also on his bright red waistcoat, which is immaculate in the rest of the scene. (00:08:00)
