Revealing mistake: At the beginning of the scene near the end of the movie with Lucius Malfoy fuming at Dumbledore in his office, Malfoy's hair is fanned back behind his shoulders. The lighting in the room illuminates the back of his neck, where you can see his real, short brown hair. (02:22:05)
Character mistake: When Sir informs Kelly that she made the drill team, he says Captain Rigby instead of Major Rigby.
Other mistake: Even though it is snowing throughout much of the movie, none of the snow seems to stick to any of the characters' fur. Even during the fight scene when they are rolling around in it, they are never covered with white.
Continuity mistake: During Marty's drive to the bogus address, when he is done speaking with Monty, just as he says, "Wolf out!" he pulls the phone wire and the earpiece actually pops out of his ear, but in all of the following shots that earpiece is still in his ear. Since the super-glued earpiece is one of the main plot points, this is bizarre to say the least. (00:44:25)
Character mistake: When Stuart calls home from the pay phone he's talking into the wrong end of the phone.
Continuity mistake: In the beginning of the movie during the skateboard scene with Shaggy and Scooby riding along the conveyor belt, Scooby grabs a hook and both Shaggy and Scooby jump off of the skateboard. You see the skateboard falling off the conveyor belt, but in the next scene it is on the conveyor belt and being crushed. (00:03:20)
Continuity mistake: Carmen is wearing white sneakers riding with Juni on the magnetic transporter. After jumping off the magnetic rider and entering the hidden temple, Carmen is wearing black sneakers.
Continuity mistake: After their surf-adventure, in the scene where Nani and Lilo are sitting and singing in the hammock, there are two torches which keeps appearing and disappearing.
Continuity mistake: When Ox throws MJ's shoes onto the wire, there is no tree beneath the wire where the shoes fall, but when Calvin climbs onto the tree, there is clearly a branch underneath the shoes.
Continuity mistake: Although Gothel cuts Rapunzel's really long hair using a spell, at the end of the movie when Rapunzel gets married, for some reason, her hair is still long, even though it had no time to grow back.
Continuity mistake: When the Powerpuff Girls use their laser eyes to make windows in their room, the windows are oval. Later in the movie, such as when the Powerpuff Girls are sleeping the night before 'The Day', the windows are circular.
Plot hole: In the scene when the robbers first enter the house, Kevin goes to hide in the shower. It looks like there is only one way out of the shower. How can Kevin possibly get out of the shower, let alone the bathroom, without getting wet after he turns it on?
Continuity mistake: When the Owls are playing for their district championship, the other team's best batter comes up in the last inning. As he is walking to the plate, he is wearing Nike shoes, but when he digs into the batter's box, his shoes are Reebok.
Continuity mistake: In the scene where Santa is getting married, just after they kiss and Santa looks like Santa again, you can see in the bottom left hand corner Bernard and Curtis giving each other the thumbs up. In the very next shot, it repeats them doing this again only in a close up. (02:33:00)
Visible crew/equipment: When Ted is sliding down the hill after being chased by a bear, you can see a plastic sled on his back.
Other mistake: When the Pirates are arrested in Nineveh, another soldier walks up to Jonah and knocks him out with a fish. When this happens, Jonah is wearing the Cheese Curl hat. When he comes to on the Slap of No Return, he is wearing his turban again. Would the soldiers change his hat?
Continuity mistake: Ray comes to Buck's hotel room with the stolen disk containing the revised speech. At the shot when Buck is sitting at the computer reading the speech, he has a wedding ring on. Buck isn't married.
Continuity mistake: When Dr. Doppler and Jim first observe their ship, Dr. Doppler is right next to Jim when he points it out. When the shot changes to a long shot, they're much farther apart. (00:16:55)
Factual error: After Berry and one of the Country Bears get in the bus to find the others, they show a scene with the bus going along a road and Berry leans out the window. Here you can see the side of the bus is spick 'n' span clean. Then, later, the bus is as dirty as it was when it left the shack, very noticeable at the start of the carwash scene.
Other mistake: When Arnold and Gerald first bump into Helga at the bus stop, they ask her for bus money, but throughout the rest of the movie they never need bus money.
