Continuity mistake: When Sarah shouts, "Quick, this way!" and then Sir Didymus shouts, "No, not that way!" the hanging sign with the hammer hangs crookedly by only one chain. However, two shots later when Sir Didymus shouts, "You're going the wrong way!" the sign hangs properly from two chains. Then later, when the three Samurai Goblins jump in front of Sarah and the rest, the sign's chain is broken once again. (01:20:00 - 01:25:40)
Continuity mistake: At the Policeperson's Dance, Copeland spills punch over the Commissioner's wife's white dress. As the camera view switches, her dress is already stained before she is splashed.
Revealing mistake: When Jim hits the brakes in his stolen patrol car, the two pursuing police cars turn and flip over and over. As they roll, the 'roll cannon' is visible on the underside of one of the cars (a round steel tube in a hole in the floor) and at left, the two cannon slugs from both cars bounce down the road. This device fires the slug downward, and the force behind it lifts the car when the slug hits the road, launching the car over.
Continuity mistake: Just before we see Johnny fall off the bridge we see a shot of him speeding past some roadblocks. Look at the size of Johnny compared to the roadblocks. They are practically bigger then him. This was obviously a small replica robot filmed with the camera on the ground, to give off the impression it was the real thing. (00:20:45)
Continuity mistake: When Max and Joey take a picture at Luigi's house, Joey is looking at the camera and not smiling while Max's hand is just below Joey's right ear, getting ready to grab it. When Max makes a copy of the picture later, Joey is looking away from the camera, smiling, and Max's hand is on Joey's shoulder. (00:50:50 - 01:14:40)
Continuity mistake: When Jason kills Lizabeth, the first shot shows Jason with his feet on either side of her head, but in the next shot, his feet are together and away from her head. (00:14:35)
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)
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 Connor McLeod decapitates Fasil, the wide shot shows that Connor swings his sword with one hand but the close-up shows that he's using both hands. (00:09:25)
