Other mistake: Meowth calls one particular Pokémon in the test tube-thing a Sandshrew, however it is a Sandslash. This is a dubbing error, as Nyasu (Meowth's Japanese name) correctly identifies the Pokémon as a Sandopan (Sandslash's Japanese name) in the original Japanese version. (00:58:26)
Other mistake: Near the end of the film there is a stand-off, if you look in the sky an aeroplane flies by.
Other mistake: When Crickie is typing the letter for Mushu he has ink on his feet yet when he jumps on the table to wipe off his feet there aren't any ink footprints where his foot was.
Other mistake: The shot of Big Ben destroyed by lightning looks strangely like the Big Ben exploding in the film "Mars Attacks" (1996).
Suggested correction: Whether or not it is the same footage or just similar, it's not a valid mistake as there no continuity or factual errors involved, etc. It's trivia at best, if the two films can be tied together and there's documented reports of someone involved in the films admitting the footage was reused.
Other mistake: When Quin is cutting the plane that's stuck in a tree, he uses a saw, that looks brand new. He's just been chased by pirates and jumped off a cliff - where did he get the saw from? Anything in the plane would be rusty by this point.
Other mistake: After the song 'Love Will Find a Way' when Kovu and Kiara are peering into the water and Kovu says, "We are one," in the reflection the scar on Kovu's face is on the wrong eye. Nothing to do with it being reflected, it was on the eye nearest Kiara, and now it's on the other eye.
Other mistake: Wouldn't flying out of the water with the unconscious Z in his arms be kind of tricky for Cutter, as his wings would be soaked?
Other mistake: When Data discovers the holoship in the lake he reduces the amount of water in the lake significantly (The ship is now clearly visible, standing out several meters). But even so the banks and the landing stage are still in their correct position. If the surface level had been reduced the landing stage should have been standing out of the water, too.
Other mistake: When Jackie is falling through the trees at the beginning, you can easily tell he is on strings because he would hit the branches with a lot more force than he does, and also wobbles in certain ways which would be impossible to do in this situation.
Other mistake: When the Musketeers are charging the firing squad at the end, they only have about 20 yards to run which they should cover in just a couple seconds, but somehow it takes them much longer to reach the other men. This is especially noticeable since they're running at full speed. (This has nothing to do with editing or slow-motion, as most of the shots are shown in real time, at regular speed.)
Other mistake: When Bidwell comes back from being mauled by the bear, he has a wooden "crutch". When you see him up close the crutch is sawed or finely cut on the top. He was lost in the woods so I don't think he could find one of those.
Other mistake: When Chip Hazard's chopper is shot down, he jumps clear before it goes down. But he jumps up, and at the height his leap takes him, he should get his head chopped off by the rotors.
Other mistake: Jack is rescued by Bridget at the train station where he is being pursued by Sandra (an alien). Bridget shows up in her car and drives him away so Sandra cannot catch him. But Sandra and Bridget have never met. How could she know Sandra was a threat? Even more confounding, how did Bridget know to find Jack at the train station? He was randomly thereafter jumping out of the car he was being abducted in. (00:50:30)
Other mistake: When Cody stole Barney and was running from Abigail and Marcella he hid in the closet, but the girls thought he went to the attic. When he came out of the closet the door made a creaking noise. If the noise was made when he went in, then the girls would have known he was in the closet rather than thinking he went to the attic.
