Factual error: Near the beginning of the film before James McAvoy heads up to the house for the evening meal, he is seen looking up through a skylight when a Lancaster bomber slowly flies overhead. At the time it was was supposed to be 1935. The Lancaster bomber did not fly until the beginning of 1941. Can't be an Avro Manchester either, they only had two engines and first flew in 1939.
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: The husband was killed in an explosion. There would be no body for a casket, much less a head full of hair.
Factual error: In the final scene where Congress is supposedly passing the bill, they are still in the committee room. Bills are not passed there, but in the actual meeting halls of the House and the Senate.
Factual error: In the final scene, when Jack Sparrow is looking at the map to find the Fountain of Youth. The map lists Ponce de Leon's travel date of 1523. The actual date of the Fountain of Youth founding was 1513.
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: When the wraiths first invade the stockade, one of the officers orders his men to fire their "rifles". This is the 16th century. They're firing muskets.
Factual error: When they are trying to escape by helicopter 2 fighters pop-up and shoot with their machine-guns on the snakes head but when you see close up its raining bullets on their heads while those 2 planes are floating next to the building not above it.
Factual error: The kitten in the Viking scene is long-haired. Long haired cats did not appear in Europe until many centuries later.
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: The Human Torch chases the Silver Surfer into the Lincoln Tunnel at 29:35; the entrance shown is on the New Jersey side of the Hudson River (although they had just been in Manhattan seconds before, they were airborne and could have gotten there from the sky). When they collectively exit the tunnel at 30:01, they are still on the New Jersey side, as evidenced by the toll booth clerk who witnesses their flyby. While both the entrance and exit scenes are physically in the same a place, a large American flag was either pasted into the entrance scene or edited out of the exit scene, creating a slightly different visual element to two otherwise identical landscapes. (00:29:35)
Factual error: In the scene showing Septimus swimming underneath the water after having dived through Capt. Shakespear's cabin window, you can see Septimus holding his fighting knife in his right hand. After a stroke or two he lets go of the knife and it doesn't sink.
Factual error: Early in the film, Chris foils a casino shooter, steals a car, and leads police on a high-speed chase through Las Vegas. He has a psychic vision of himself being smashed into oblivion at a railroad crossing, so he knows he must accelerate to 120 mph to beat the train. The camera cuts to a head-on view of the train, and this time Chris goes flying over the crossing, just barely missing the train. Oddly, there are no barricade arms with warning lights at the railroad crossing, even though this train is screaming through an urban area. Additionally, the car is already levitated about 3 or 4 feet in the air long before it ever reaches the railroad crossing, as if it hit an invisible launch ramp. Thus, Chris makes his escape as the train blocks any further police pursuit. We then see two angles of the fleeing vehicle suddenly make a hard left turn down a side street about a block past the railroad crossing. Which is physically impossible. Given that he air-jumped the railroad crossing at 120 mph, Chris could never have slowed down enough to make a hard left turn within one block. It would require more like 10 blocks to slow down to a manageable turning speed, if he could regain control of the car.
