Factual error: When animated Giselle begins to sing and brushes her hair, the reflection of her "one true love" is visible in the mirror. Problem is that its image is not reversed in the reflection. (00:02:00)
Factual error: When Mr Bean arrives in Paris from his Eurostar train, he arrives in Paris Nord train station. In reality, the Eurostar platforms are fenced off to prevent train-hoppers and are against the station wall, rather than the middle.
Factual error: In the final surfing scene, Cody and Z are surfing, presumably, off into the sunset. However, being on the north shore (given Z's remark a few moments before), that would mean the wave is rolling to the south which would put the sun toward the east not the west. (01:20:00)
Factual error: The restaurant Joe opens and his apartment at 1 Charles are actually less than a city block apart, so there is no need to drive across Boston to get there.
Factual error: When Wilbur tosses Lewis onto the time machine, he should have broken or hit the glass covering the back half. And he is on all fours when the machine becomes visible, which shows he would have had his face hitting the driver seat, yet he scrambles back into the passenger seat without a problem, then is seen barely leaning forward to talk to Wilbur in the future.
Factual error: Trudie and her family are released from jail because David, being the victim of kidnapping, decided not to press charges. That's not how things work. It's not up to the victim to decide whether or not to press charges. It's up to the prosecutor to decide or not to press charges.
Factual error: When Chuck discovers the dry rot, he tells the Persons that he played 36 seconds for the Lakers in the 1986 NBA Finals. The Lakers weren't in the 1986 Finals.
Factual error: Loch Ness is an inland lake with very limited access into the open sea, or at least much less than portrayed in the film.
Factual error: The creature Jess catches in the greenhouse is a Common Brushtail Possum, which is only found in New Zealand and Australia. Though the film was shot in New Zealand, it is supposed to be set in Lark Creek, Virginia, a rural area in the southern part of the United States.
Factual error: When the Chipmunks are going on tour and all of the cities are listed, it says that they're going to "Phoenix - NV" however it's clear they are in Arizona not Nevada, so it should have said "Phoenix - AZ." (01:02:40)
Factual error: After returning to the Dursley's after the dementor attack It is dark, this shows again when Vernon puts Dudley in the car. However, the howler from Mathila Hopkirk says that at 6:23pm Harry performed illegal magic. As the side story shows it is a hot summer, it wouldn't get dark until way past 8pm. (00:04:53 - 00:07:20)
Suggested correction: Fairly certain the film was clear that the reason it got dark was because of the dementors, they have the ability to change the weather to depressive darkness.
Factual error: When the girls talk at the beginning of the movie, they can fully hear and understand each other even when they are at massive distance from the webcams they are supposedly using to communicate.
