Other mistake: Right at the beginning of the movie, when Lewis's real mum picks him up from the box and hugs him, it's no more than three seconds before she hears Lewis from the future slipping on the step. She gets scared and puts baby Lewis back in the box. When Wilbur takes Lewis to meet his mum, near the end of the movie, the time his mum holds the baby is more than twenty five seconds.
Factual error: When the car goes to the bottom of the ocean after the chase, the water in it is raising as if leaking in, despite the fact that the door on Hiro's side is missing and the water should be rushing in. (00:50:15)
Suggested correction: I watched the scene and it looks like it's filling up the way it should. It's looks similar to the way a car fills up after being submerged with the windows open.
Not true, water is still filling up the car way too slow for an opening like this. The car should be filled up immediately.
You're wrong thinking it would fill up immediately. But even so, it fills up in about 10 seconds (even less if the shot of it filling up is meant to be a simultaneous shot and not continuous).
Continuity mistake: When Arthur is out hunting in the woods, Arthur is lying on a tree branch. In one shot, his pants leg is coloured brown, whereas, in the next shot, it is skin colour (as if he isn't wearing any pants). In the next shot, the brown pants leg has returned.
Continuity mistake: Early in the movie when Thomas falls overboard, John Smith ties a rope around his waist (00:02:56) and jumps in after him. Thomas is very far away from the ship (00:03:12). But when the men pull John and Thomas up, John is holding on to the rope with one hand and the end is left dangling (00:03:36). One of the men who pulled them up then coils the rope with a mere two coils (00:03:48), not nearly long enough to have reached Thomas while he was overboard. In the same scene, when we are viewing the men pulling John and Thomas up from above (00:03:38) there is no extra rope at their feet as there should have been for such a long rope.
Continuity mistake: While Pooh and his hungry tummy are searching for honey Pooh finds himself at Owl's house, and in the first wideshot we can see the wood sign that reads "Dont nock plez ring" with nothing above it, but once Pooh reads the sign suddenly Eeyore's tail is hanging above the sign as a bell-pull. (00:48:25)
Continuity mistake: When Taran, Princess Elonwy and Fflewddur try to escape from the Horned King's castle, Taran opened the gate by removing the chains. The next shot the gate is closed and chained, the last shot the gate is open again, and the boat is pushed trough by Taran. (01:06:33)
Plot hole: In the scene where the Sheriff stops the cows' brawl, he gives them to the Chinese man. The Sheriff knows what Pearl's animals look like, so why didn't he recognize the cows as Pearl's?
