Continuity mistake: When Tommy Tong breaks Jarrel's stick, the broken part of the stick differs between shots. (00:33:40)
Continuity mistake: Connor decapitates Fasil holding his sword with one hand, but the close-up shows that he's using both hands. (00:09:25)
Continuity mistake: At the beginning when the helicopter lands, the helicopter's shadow goes out toward the rear right of it (from the pilot's perspective), but when Sue grabs her bags and walks to Walter, the shadow is now cast to the front right. Since Sue got out and was standing next to it, the helicopter did not move in the meantime. (00:03:15)
Continuity mistake: When RJ sits on Jason's midriff he is eating a Popsicle with chocolate on it but in the next shot the chocolate its completely gone. (01:05:30)
Continuity mistake: When Jack Burton and the rest of the gang escape from the Wing Kong Trade Centre the first time, the guards fire at the left side of the bus breaking the windows and making holes in the bodywork. When we see the bus a few seconds later as it is driving away, it appears undamaged.
Continuity mistake: During the chase scene where they attach the "engine killer" remote to the Dodge M4S (aka Wraith's vehicle), 2 Chevy Malibu Cop cars are barreling up the road towards the racers. Once the cops pass the starting line, the cars are now Dodge cop cars. (00:44:25)
Continuity mistake: When Dennis's girlfriend goes to see him at the godfather's house, her car is seen parked directly in front of the house, where the godfather's car was just parked moments ago. (01:18:55)
Suggested correction: Well, yes and no, or rather "no and maybe." The godfather's car was parked far enough from the stairs for another car to park closer, between Pazzo's car and house. And it's what happens here. However I do think there could be a continuity issue with one of the exterior shots when Pazzo's car seems to have been moved quite a bit off position compared to before. The mistake could be there but not as big as it appears to be (I kinda find it hard to judge due to the angle by how much really the car is off position, even, since it's a significantly different one from before).
Continuity mistake: After Howard beats the punks' asses, Beverly's umbrella briefly disappears from her bag. (00:11:23)
Visible crew/equipment: When Skip has just finished snorting cocaine and is talking to Stella, the boom microphone is visible on the top left of the screen.
Continuity mistake: In the scene where he is fixing breakfast for his daughter, Robert Redford's shirt sleeves are down. When he goes to rescue the burning toast in the oven, his shirt sleeves are up and then they are down again. (00:15:00)
Revealing mistake: The chairman parks his car in front of Bel Fuse Ltd. And goes upstairs. His car explodes, but does it in front of a different building, probably switching to a stage building front; the metal doors don't have vents anymore and there are visible join lines in the asphalt and the cement. (00:15:10 - 00:15:40)
Revealing mistake: When Amy falls in the river, she is replaced by a stunt with a blatant, bulky wig.
