Character mistake: Before he scampers inside to spy on the humans, Claudius tells the other animals, "I'm your mouse on the inside!" Maybe he should check a mirror while he's in there. Claudius isn't a mouse - he's a rat.
Character mistake: Near the end of the movie, Charlotte says she doesn't have the strength to climb down into the crate. Two seconds later, she climbs down to comfort Wilbur, then climbs back up. Even if she couldn't go all the way to the crate, she was low enough that Wilbur could have carried her there himself.
Character mistake: When in the mineshaft Trevor says that magnesium is used in gunpowder. That is not correct.
Character mistake: When Barb introduces herself to Flint, Steve calls her a monkey, and she corrects him saying that she's an "Orangutang", pronouncing the G at the end. But the correct word is Orangutan, with no G sound. Barb would surely know this, as a genius ape.
Character mistake: In the scene when they do the weigh in, the camera man recording Ben does not even have the tape door pressed into the camera, so nothing is being recorded.
Character mistake: When young Alan is talking young Sarah, he says that he found a board game at the factory. Alan didn't find the game at the factory. He found the game across from the factory at a construction site.
Character mistake: When the coach is eating a sandwich in the locker room, there is a headline in the paper he's reading that says, "Diamond Backs rattle Timber Wolfs..." Diamondback is one word and the plural of wolf is wolves. (00:45:00)
Character mistake: When looking at the newspaper about Chester Copperpot, the caption under his picture reads, "Reclusive scavenger claims, 'I have they key.'" It should read "I have the key."
Character mistake: At the ravine, upon learning that the bridge doesn't exist yet, Marty states to Doc "We can't wait a year and a half for this to be built". If you carefully look at the sign, it says the bridge is opening Summer 1886. That's under a year away, not a year and a half from Sept. 1885.
Character mistake: Before the junk man drives away he calls Mr Coggins "Bill." The correct first name is George.
Character mistake: At the beginning of the movie, during "Provincial Life", we see a fat lady trying on a hat in a hat store. The sign over the window, in French, reads "Chapeau" (hat). The correct way to identify that store would have been "Chapeaux" (hats) or "Chapelier" (hatter).
Character mistake: At the beginning of the cartoon, there is a sign which reads "IF YOURE LOOKING FOR FUN" with no apostrophe.
Character mistake: The registration number of the stolen van is GPW729 but every time it mentioned in the dialogue it is stated as GPW927.
Character mistake: During "The Bare Necessities", when Mowgli climbs onto his back, Baloo asks him to scratch his left shoulder; Mowgli then proceeds to scratch Baloo's right shoulder.
Suggested correction: Mowgli starts with the left shoulder. After that he moves over the back when Baloo arches and ends up on the right shoulder.
Suggested correction: Mowgli has lived with wolves for God knows how long. Wolves wouldn't just teach him the difference between left and right when they could teach him how to feed himself. For this reason, Mowgli could get it wrong. Also, the bear could've muddled up his words without realizing as, again, it isn't necessary to know left and right.
Character mistake: When Harry takes the kids to his business, he's showing them how he "restores" cars. After putting the bumper on, Harry says, "Transmission. The sawdust quietens the gears and let's the engine run as sweet as a nut." Putting sawdust into the transmission would not change how the engine runs as they are two separate components. It may make the transmission quieter but would have zero effect on the engine.
Character mistake: When we see what is happening inside the saloon, there is a sign which reads "Noisy - Is'nt It?" It should read "Isn't."
Character mistake: The batter hit a line drive hit over the second baseman Garcia's head. The pitcher Bass whips his head to his left as the ball goes to right or right center field. The announcer said there's a base hit to left field when it was right field.
Character mistake: When Thunder Jack first arrives at the cabin to buy the dogs from Ted, you hear him yell whoa to stop his sled dogs. After Ted is sprayed by the skunk, Thunder Jack is explaining the proper way to stop the sled dogs and says that you yell "hook and brake".
Character mistake: When Marian is correcting Amaryllis for the girls' poor grammar in saying "can I" instead of "may I" over the cross-hand piece, the girl then asks if she can go play that cross-hand piece and Marian replies, "now you can play your cross-hand piece."
Character mistake: Archimedes says he told Arthur not to pull the sword out of the stone. He didn't, he pointed it out in the churchyard to him instead.
Suggested correction: Archimedes was trying to be helpful when he pointed out the sword so Merlin could take it to the tournament. But after it became a big issue with the rays from heaven and the legend, Archimedes thought he might get in trouble so tried to act innocent by fibbing. It was deliberate and in character, not a character mistake.
Suggested correction: The construction might very well be part of the factory, a new factory building for example.

The sign at the construction site said it was an "Executive Office Annex" that they were building.
Bishop73
Even though the sign said it was an Annex, construction was still being done outside of the main factory where Alan found the game. Not inside of the main factory itself.
