Revealing mistake: Bruce Willis wore fake feet during the movie to protect his own while shooting the film. They were like boots that slipped on over his. At the part where the FBI guy shoots at him from the helicopter and Bruce jumps to a lower level of the roof, you can see the tops of the fake feet that aren't tight around his ankles. (01:50:30)
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: In the scene in the apartment, where the Terminator cuts the flesh away from his damaged eye, he picks up a hobby knife that has a blade attached. In the next shot, as he lifts the knife up toward his eye, the blade has disappeared. Then in the front-on shot the blade is back again. (00:52:35)
Continuity mistake: When DeVries' Ferrari crashes into the fence, the license plate is lying crooked, touching the bumper. When the cops blow it up, it's not touching the bumper. Also notice that the petrol tank and exhausts have been removed, revealing that the car blows up by explosives rather than police gunfire. (00:07:40)
Continuity mistake: When the Terminator pulls John off the dirt bike during the drainage ditch chase, the dirt bike falls onto its left side and the gas tank is about to be crushed by the tow truck. The next shot from another angle shows the dirt bike laying on its right side, with the rear tire the first thing to be crushed under the truck. (00:37:30)
Continuity mistake: The licence plate of the taxi which hits Sebastian in the end changes during the shot. (01:27:35)
Continuity mistake: When Vader's shuttle is approaching the Death Star, the crew in the control room of the Death Star are wearing black gloves. One of them then reaches forward to press a button, but in the close-up of his hand pressing the button, the hand is not wearing gloves at all. This can only be seen in the widescreen version. (00:02:25)
Factual error: In one scene, focused on a period wood-staked pickup truck parked on the street, you can see clearly a modern Jeep Grand Cherokee parked on the other side of the street.
Revealing mistake: At the beginning, when people are walking through the metal detector and on the screen it shows them nude, the background is different on the screen. For example, the screen shows two people sitting down, but there are no people sitting down. (00:02:35)
Continuity mistake: When Homer and Bart are on the motorcycle trying to get rid of the bomb, the bomb slips out of Bart's grip. When he's hanging onto his father's shirt, Bart first grips the bomb's handle with his palm and fingers facing the front of the bomb, with the clock. Then when he's hanging onto his father's hair, Bart's hand has flipped around and he's now gripping the bomb's handle with his palm and fingers facing the back of the bomb. Something to look out for is the shot just before the close-up of Chief Wiggum, because as Bart raises his arm the bomb actually flips over in his hand while we're watching. Quite impossible. (01:12:55)
Visible crew/equipment: A boom mic operator wearing a white shirt is seen reflected in the door that the female scientist opens, when the Umbrella personnel pick her up, as part of their extraction procedure. He is visible as the door is opening and very faintly when it is closed. (00:04:00)
Continuity mistake: As Mr. Fletcher is riding up on horseback to greet Lady Ashley, you can see him riding up next to a parked, red truck, that has the front end pointed away from the house. Keep an eye on that truck, because it will have the front end pointing towards the house, as Fletcher gets closer to Lady Ashley. (00:27:50)
Continuity mistake: At the Ministry of Magic, as Yaxley is reprimanding Ron, who is disguised as Reg Cattermole, the initial on Yaxley's Ministry tie pin changes direction. In one shot, the letter "M" is tilted to the left, and in a subsequent shot, it's slanted in the opposite direction.
