Other mistake: After they take off from California, Kirk gives a heading to Alaska. He then tells Sulu "full impulse power", and Sulu says "aye, ETA 12 minutes." Full impulse is 1/4 the speed of light. No way they would use speeds like that to go a few thousand miles.
Other mistake: Teddy's hair changes in every shot after being dunked in the swamp. The strap to his bag disappears and reappears as well.
Other mistake: In Sarah's room, after the close-ups of Lancelot's empty shelf space and of Sarah beginning to say, "Someone..." as she finishes, "..has been in my room again," in this wide shot, while still on her bed until she leaves her room, there is a mark across Sarah's forehead that extends to the left side her eye. It isn't in the previous or following shots. (00:06:40)
Other mistake: When they first get into space and Tish removes her helmet her left earring is free floating, which would be expected in zero gravity. But after this first shot, her earrings hang down as effected by gravity. Also all three of the girls hair hang down with gravity the whole time they are in space. (00:54:45 - 01:03:15)
Other mistake: How does Dola know that Sheeta's pigtails were shot off? They had been outside in their aircraft the whole time and once Dola got Sheeta in a tight hug, the situation doesn't call for any time for her to explain what happened.
Other mistake: During the final showdown with El Guapo, three horsemen ride towards some fake Amigos and fall into a concealed ditch, throwing up their arms and falling off their horses. Unfortunately, they throw up their arms just before the horses even start to fall.
Other mistake: When Fievel And Tony reunite on the streets of New York, Tony gets a piece of cheese off of a mouse trap. Watch that piece of cheese, cause Tony throws it up in the air, and you never see it come back down. (00:33:25)
Other mistake: When Nick and Sue go to the outback with Wally they go by car then by boat (the only way to get to where Mick was bitten, apparently). Once they are there the poachers from the pub appear on their jeeps to hunt kangaroos. So there was a direct way by car to the spot.
Other mistake: The credits for the movie say that they are in alphabetical order, but Peter Cullen is listed before Scatman Crothers.
Other mistake: In the scene where Howard falls asleep in Beverly's apartment window and his wallet falls out, she takes out the money. The city on the bill says Washington DC instead of Marshington DC. (00:19:00)
Other mistake: One of the taglines for this film was "Meet Jim Ferguson. He lived a daring double-life with one foot in the 20th century and the other in World War I." World War One was fought in the 20th century.
Other mistake: After Jack climbs up the ladder and through the floor he then runs right to the locked door, all this takes about ten seconds. Somehow in those few seconds Wang, Gracie, and the rest of the girls have all made it up the same ladder and coming around the corner when he gives him the signal to come to the door when there's no way they couldn't have all done it that quickly.
Other mistake: Lakella seems to disappear from the movie after the battle.
Other mistake: When examining the craft in the hangar, it's reported there are no seams or any way in or out, but when the camera focuses on the man's hand, you can see the seam where the hatchway will be.
Other mistake: As the plane is beginning to crash, Chuck grabs the watch with his girlfriend's photo in it, and somehow it survives everything, but how? He had the watch in his hand, but in many shots we can see Chuck with both hands open as he needs them to hold onto something. He didn't put it in his pocket, he didn't have time.
Other mistake: During the fight on the dam between von Ragnar and Lance, the protective cover of von Ragnar's deadly middle finger nail is never seen until the closeup shot of von Ragnar removing it.
