Other mistake: There is a scene in which Piter DeVries is talking about the Landsraad (one of the governmental organizations in Dune). Twice he mispronounces the name, saying "Lansdraad" instead.
Visible crew/equipment: When a gremlin attacks the Mum from a Christmas tree, and the tree falls on top of her, you can clearly see a member of the crew with eyeglasses, wearing a red shirt, standing behind the tree pushing it forward on top of her. (00:54:30)
Visible crew/equipment: When Freddy falls over the banister onto the stairs near the end, notice the crash mat he lands on. (01:18:55)
Audio problem: When Nighthob and Teeny are talking to the Rockbiter near the beginning of the film, Teeny says to Nighthob "This could be serious", then turns to Rockbiter and calls out his name. Watch Teeny's mouth as he calls out "Rockbiter". You will see a very blatant editing mistake as Teeny is not actually saying 'Rockbiter", but is saying the next line that follows. (00:16:40)
Revealing mistake: When the TVs explode, the glass is very fake and "cardboardy".
Factual error: In the very beginning sequence, as the riders are galloping triumphantly across the mighty windswept plains of yore to capture Conan, you can see power lines in the background in one brief shot at the very left of the screen.
Visible crew/equipment: When the two lead characters pull up to a stop in the car, the shot is dead-on from the driver's side, and you can clearly see the entire camera crew reflected in the side of the car. (00:30:10)
Revealing mistake: There are two Ewoks Wicket's parent is in search of. One of the those Ewoks is climbing down a mountain and the other has finished climbing down. As this happens, look at the Ewok not climbing. As he bends down, half way down his left leg, there is some sort of fold there. This is mainly due to the fact that the Ewok actors wore costumes whilst filming. The fold is coming from the Ewok costume. (00:07:50)
Revealing mistake: When the guy on the horse pulls out his sword, he has trouble getting it out of the sheath at first and it bends severely. It is clear that it is not a real sword.
Continuity mistake: At the beginning of the movie, Selena drives her car to the right side of the house. When the shot changes, the car is several feet further back and is now heading across the front of the entrance.
Continuity mistake: After crashing through the guarded barrier of the base, David drives the stolen pickup truck and burning debris from the electrical storm falls onto the hood of the truck. In the next close-up the burning debris is shaped differently. Then after they crash through the wall, in the wide shot there is no burning debris on the hood. Yet, in the next close-up there's plenty of burning debris, but then in the next shot there is no burning debris again, just a smoking engine. The building debris surrounding the truck and behind it, in the first shot differs from all the building debris in the second shot as well. (01:21:50)
Deliberate mistake: In the end sequence, when the joyous Valley of the Wind people run past Yuppa and the old woman to welcome back Nausicaä among the living, the same group(s) of people are seen twice running from the right to the left.
Continuity mistake: When God and the Devil meet, God tells him that he wants the kid back. You see the Devil holding the cards in his hands. The camera angle changes and the cards are now on the table. The camera angle changes again and the cards are back in his hands. Happens about 3 times during the scene.
Revealing mistake: When Roger is in the bathroom at the urinal, he can see Edwina's reflection in the mirror (as she is, supposedly, inhabiting his body). However, when Roger lets out a particularly big exhale, Edwina's bangs blow slightly upwards, showing that the "mirror" effect is achieved by simply having her stand behind a wall right in front of him. (00:29:45)
Continuity mistake: When Billy inspects Christie's sword, he's holding it hilt up in the wide shot. In the close-up, he's holding it hilt down. (00:30:30)
Revealing mistake: When Bob Cratchit takes Tiny Tim by the town square to watch the boys play, you see many boys "sliding" on the ice. In the close-ups of the boys you can see the "ice" ripple beneath their feet, revealing it to be some sort of plastic.
Continuity mistake: When the prince drives the jeep, his hair is short, as opposed to the POV shot where he has a really big afro.
Character mistake: The ref says there's no rules before McClure fights Whiplash but she tries stopping them later.
