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.
Other mistake: The fire truck passing by Nani on the way to her destroyed house has the same license plate as the gas truck that Stitch hijacks.
Other mistake: While downstairs Vernon hears Hedwig's squawks, as well as Dobby and Harry's exchange in the bedroom upstairs, distracting enough for them all, including the Masons, to take note. The noise upstairs illicits a reaction from everyone, which Vernon explains is a noisy cat. Yet when Harry very noisily chases Dobby down the steps, Dobby slams into the wall and Harry lands with a loud thud (not remotely 'catlike'), Vernon, who stands on the other side of the shared wall, pleasantly continues his story to his rapt guests, who are also not distracted by the noise. To suggest that such loud noises coming from the hallway right beside them would not draw any reaction from anyone, Vernon and the Masons included, is preposterous. (00:06:45)
Other mistake: When Marty Wolf gets out of his pool, his shorts aren't dyed blue. If that one little bottle of light blue dye was enough to dye Marty Wolf's skin, it certainly would have dyed his shorts.
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?
Other mistake: The little girl elf pours Santa a mug of hot chocolate, but if you watch closely there is nothing in the mug when he drinks it.
Other mistake: In the beginning of the movie where Baby Jim is talking about Treasure Planet, he crawls under the top sheet of his bed that has been folded half way up the bottom of the bed, and peeks out the bottom. That's fine and all but then his mother straightens out the sheet and covers him up. You then see that the part he just peeked out of was the folded part so he shouldn't have been able to peek out.
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.
Other mistake: When Margalo lands in Stuart's car after escaping the Falcon, Stuart slams on the brakes, only he hits the gas pedal instead of the brake.
Other mistake: The story takes place during Christmas time, yet there are still plenty of leaves on all the trees.
Other mistake: Fleeing with Little Creek from the fort, Spirit destroys small railing to free horses tied to it. But after the pole gets torn off, it leaves an empty space on the ground, without any hole or at least broken remains.
Other mistake: All the baseballs used in the movie (or at least the ones you can see up close), were official Major League Baseballs. At the time the movie is supposed to take place, 1999, Rawlings made separate baseballs for the American and National Leagues. The official Rawlings Major League Baseball wasn't used until 2000.
Other mistake: When the gang is in the mystery machine and Scrappy pees on Daphne and they kick Scrappy out of the car, from a distance the driver isn't Fred - it is someone with dark hair, not blonde.
Other mistake: When Carl and David go down in the submarine, they come across the sunken plane that they crashed in. As they approach the plane, it shows that the it is clearly on the right side of the sub as they go from the tail to the prop. When it cuts back to them in the sub, they are looking to the left. A cut back to the plane still shows that it could only be on the right. Carl then looks out the left port hole of the sub and it clearly shows them going by the plane from prop to tail.
Other mistake: When Gary and Gerti fall in the camel poop, there a few things wrong with that: 1) camels poop in "pellets", not like what you see in the movie; and 2) Gary and Gerti are both in the centre of the pile when they should be at the end of it. They are both in the same spot (it has nothing to do with leg length).
Other mistake: When Pistachio is tripped and the spaghetti dinners fall on four customers heads, there is one man with spaghetti hanging all down his face. This man wears glasses, and somehow the spaghetti is hanging behind his glasses, instead over hanging over them. (00:09:50)
Other mistake: Every lake is frozen over enough you can walk on it except the lake where he falls. And he would have died of hyperthermia in 10 minutes or less, being wet.
Other mistake: Dad has a long drive home, travelling through the mountains during a snowstorm. Dad pulls into the driveway and his truck is clean, with no splash marks. (01:12:05 - 01:14:35)
