Plot hole: Although the errand bird always insists on the postage and even asks for additional fees for more than twenty words, he never gets any payment from the assigning characters.
Plot hole: Michael Jordan is from North Carolina. If those were really his shoes, how did they make their way to L.A?
Plot hole: When Joe takes Black Beauty and Ginger away from Birwick Park to their new home, he is about 11 years old. When next Beauty sees him at the fair, he has aged to his early/mid twenties. This would indicate that Beauty had been at the home of the Lord and Lady Wexmire for about 10 years but not a single character in the household ages a day during his time there. His stay would appear much briefer than that.
Plot hole: It's one thing to have a small amount of liquid nitrogen (about the size of a standard propane tank, by the looks of it from the Fridge scene), but where did the gallons upon gallons of it during the climactic flood scene come from?
Plot hole: In the scene with the brothers group, the guys don't believe that Fred is Santa Claus's brother (because they don't believe in Santa). But why don't they believe in Santa? Santa leaves gifts for kids on Christmas. If they don't believe in Santa then where do they think the presents came from?
Plot hole: Throughout the film we see several characters talk about how there's no Christmas spirit and how nobody believes in Santa anymore. If, in this universe at least, Santa does exist, it's almost impossible for people to think this. If the parents deliver the presents then how do they explain the excess gifts that Santa brings? We know that Michael is on the nice list because Santa shows him towards the end, so Michael must get presents from Santa. There is no way that Walter can't believe in Santa then because Michael gets gifts from him every year.
Suggested correction: Emily and Walter probably just thought each present Michael got from Santa was from the other parent. I'm not sure if Walter got him presents or not but you can see that Emily did as she's seen walking home with presents when she's on the phone with Walter.
That is highly unlikely. When my daughter was "believing in Santa" age, my wife and I always talked about what we were getting her, so we didn't duplicate. Plus that theory wouldn't work for single parents.
It is very likely because it's obvious Walter is not in the Christmas spirit like his wife and Michael are. Plus it's obvious Walter is not focused on his family at the beginning of the movie so it's safe to assume the original submission is correct.
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?
Plot hole: During the play Klaus climbs up the side of the building to save the baby. He gets up and finds out Olaf burned their home with a giant magnifying glass. Later, Klaus uses the magnifying glass to burn the marriage certificate. This is impossible because the device couldn't have possibly been facing or forced to face the stage. The magnifying glass was on the other side of where Klaus climbed up and when he was climbing up he was facing the stage.
Plot hole: Throughout the movie, Bladebeak works for the villains. But, during the climax, he becomes a good guy without any explanation.
Plot hole: Never in the film do the police try to stop the teams from causing havoc. There is really no way Leon has that much influence in the game. In fact, the only authority figures who really try and stop them are the security guards at the Bonaventure Hotel.
Plot hole: When Wilbur and Lewis are time traveling for the first time, Lewis says he's done with the memory scanner. Since he said he wouldn't invent Dor-15, and she went away, wouldn't the time machine and everything else in the future go away since the memory scanner started it all and Lewis decided to quit?
Suggested correction: Lewis wasn't fully giving up. He was just frustrated and probably went back to it later anyway. Whereas with Doris, he deliberately decided not to invent her because of the danger she posed.
Plot hole: When Jim is shown what he has to pay for the damages Herbie did to Mr. Wu's shop he says he has no money. First off if he had no money how in the world was he able to put down any money on the red sports car he had just purchased that night? Secondly, what happened to the prize money from all the races he was winning from the previous few months?
