Factual error: During the scene where Mozart is being carried away in his coffin by horse and cart there is a brief shot where he is being taken down a muddy path and a farmer is seen with his cows. If you look closely to the left side of the screen you can see a large overhead power line. If you look even more closely you can even see the wires coming out of the pylon. The movie is set in the 18th century and obviously it should not be there. (02:50:50)
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.
Continuity mistake: When Indy tries to grab the antidote vial from the table, in the closeup just as the vial falls off the table the camera follows the vial as it lands in the empty area to the left of Lao Che's chair where Kao Kan's chair should be, but it's not, and the rug's edge with wood floor beside Lao Che's chair though it shouldn't be. Then Indy hits Kao Kan who is again seated closely to Lao Che's left, as he should be, and when Kao Kan falls backward we see the rug edge is nowhere near Lao Che's chair, also as it should be.

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)
Factual error: While the Leonov has a centrifugal section to simulate gravity, the ship's bridge is not part of it (evidenced by the stationary views outside its portholes). Yet in various scenes, including the one when Floyd rushes in to discuss his plan to return to Earth sooner with Tanya, gravity seems quite evident. Floyd marches across the compartment onto the raised pilot area's floor, then steps down from it, his foot landing audibly. Tanya's open jacket also hangs down normally as she moves about. Yet when Floyd demonstrates his plan using two pens, they float in mid air. (01:26:50)
Other mistake: In Roy Hobbs' last at bat of the movie he takes the 1st pitch for a called strike (confirmed by closed captioning). The 2nd pitch is called a ball. The Pittsburgh manager then decides to change pitchers with the count at 1-1. The relief pitcher's 1st pitch is fouled into the press box making the count 1 ball and 2 strikes. The 2nd pitch from the relief pitcher is swung on and missed, and should be strike 3. Hobbs stays in the box and hits a long fly ball foul and hits a HR on the next pitch. Roy Hobbs should have struck out. (02:06:20 - 02:12:05)
Continuity mistake: In the scene just before Miss Piggy and Eileen get fired from the department store, Miss Piggy is watching Kermit and Jenny hug. She then bends a metal pole in half and starts hitting a barrel with it. When she first starts hitting it, the pole she is hitting it with is very thick(much thicker than the one she bent in half), is a different colour and not bent in any way. In the next shot the pole is thinner,longer and looks like the one she originally had, but it is only bent at the top whereas Miss Piggy bent it in the middle. In the next shot of her after that, the pole is now thicker (but not as thick as the first one), is not bent and the colour has changed again. Also if you look around the area where Miss Piggy is, there is only one type of pole lying around, so where did the other two come from? (00:30:15)
Audio problem: When the Terminator breaks into the police station, he has an auto-shotgun in his left hand, and a machine gun in his right. Before he kills the power in the building, he comes to the end of a hall, points his shotgun through a doorway, and shoots. A machine gun sound is used for the blast, instead of a shotgun sound. (01:00:28)
Other mistake: The chunk of hair that Ted has in the car is in a ponytail, and much longer than the hair cut off in the door.
Continuity mistake: The whole time sequence in the last part of the movie is messed up. After trying to nab the bad guys at the hotel, Tom Selleck goes home and puts his son to bed, then is called back in to work, and then the rest of the film is supposed to be the same evening, but it was already late night.
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)
