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?
Plot hole: When Sully and Mike are talking in the toilets, during Boo and Sully's Hide and Seek game, Boo comes running in screaming and upset because she's just seen Randall, and he's not too far behind since all three can hear him talking offscreen to the CDA before entering the toilets, but how did Boo get to Sully faster than Randall without him seeing her, and how did Randall not hear her screams since they're all in the changing rooms which have an echo?
Plot hole: During the climax with Van Helsing and the Kraken the writers of the film seemed to have forgotten about the powers Dracula has always had. At no point does his super speed or indestructibility ever come into play, he could have easily climbed up to the DJ booth and dealt with Van Helsing in seconds instead of going through the silly DJ battle.
Suggested correction: The kraken was faster and stronger than Dracula, if you watched he kept trying to reach the DJ booth and fight but was stopped each time and nearly crushed. It was said that the kraken was extremely strong and the only thing that could subdue him was a more powerful song than the other.
Plot hole: When the chipmunks finally release their first song, there is a montage showing the chipmunks rising musical success. In one shot we see a marquee promoting "The Chipmunks Premiere CD Release", and on it is a picture of the chipmunks in the clothes Dave has made them (note Alvin in his 'A' jumper.) However, Dave doesn't actually make the chipmunks these clothes until further on in the film. (00:41:50)
Plot hole: Near the end of the film, Carrie gets a quarter pipe. The problem is that there is no pavement anywhere near the farm which was expressed explicitly earlier in the film. Because of this, she won't be able to use the quarter pipe anyway, especially since it is about 2 ft at the base so they would definitely need to build the rest of the ramp. (01:14:00)
Plot hole: Near the end of the movie, when Mr Potts finds out that he's going to be rich (Mr Scrumptious wants to buy his invention) and he rushes out to his car to go see Truly, he meets her en route and she's got her hair in an really elaborate style and has changed. But there is no way she could have possibly got to her house, found out that her father had gone to see Mr Potts to buy his invention, changed her outfit, done her hair like that and gone out to see Mr Potts in the short amount of time between Mr Potts and his children dropping her off, and Mr Potts and her meeting at the pond.
Plot hole: The wolves seem to conveniently make an appearance to further the story, only to disappear in other parts. They are there for Belle's dad at the beginning and Belle when she tries to escape the castle initially. When Belle's dad leaves the castle after Belle takes his place and when Belle is freed to save her dad, they are not there.
Plot hole: When Dubois attempts to kidnap Alex using the tranquilizer, she is brought to a halt by several different zoo staff thanking her for returning him. The entire first movie's plot is based on them being stranded on Madagascar after being on a ship that was intended to take them away. The actions of the animals at the train station were on the news, and a large gathering of sorts was held to show that the animals were leaving the zoo. Therefore, no one should have reacted this way to his return.
Plot hole: Pinocchio drowns even though he walked along the ocean floor with no trouble just minutes earlier.
Plot hole: At the very beginning, as the passenger ship is foundering in a powerful storm, the little boy places his kitten in a box and tucks the box inside his shirt just moments before he is cast into the churning sea. Sinking into the depths, the boy and other passengers are presently rescued by Captain Nemo's team of divers, who supply the drowning passengers with oxygen until they board the submarine Nautilus. Once aboard, the little boy opens his hidden box to reveal a wet but very much alive kitten that could not possibly have survived submersion for that length of time in a box that was not waterproof.
Plot hole: In the series we learn that these creatures take a lot longer than us humans to grow up and that they live a lot longer. They mention that the children are about 900 years old, so a grown-up would be more than 1000 (probably 2000). The series is set around our time (1990s/2000s) and Fjellrose and Erke are very old. Yet the film is set about 100 or 200 years ago, you can tell by the way the humans are dressed and the way their houses are built etc. So Fjellrose and Erke should still be grown up, but they are young children. If they are only 100 to 200 years younger, then they should be much older in the film or much younger in the series.
Plot hole: Mr. Cranston asks Denise to be the accompanist for the school's production of "Chicago". This is an error. In the year 2009, in which the film is set, this would be impossible since the licensing company which has the theatrical rights for "Chicago" restricts the show from being produced (even by amateur groups and schools) anywhere in the greater New York area while there is an open-ended production running on Broadway.
Plot hole: During the final scare event, Mike gets a perfect score because Sully broke the simulator to allow the 6th scarer to get a perfect score no matter what. After the contest, the simulation resets and Mike pretends to scare the child in the simulator and it registers a perfect score on the scoreboard for the 6th scarer when it should really have registered a score for the 1st scarer, because the simulator had been reset.
Plot hole: Why is that shark machine even there? The only reason it's there is to help the plot, and I don't see how it is of use to anyone in the corporate world. If the shark just ejects the fish it turns into fish heads out to sea, there is too much chance they will be ruined by carnivorous fish or weather before they are picked up. And fishing companies should know better.
