Factual error: During the scene when Harry and Hagrid are on the motorbike going through a tunnel, the bus signals that it is going to Dartford. Both of the tunnels at Dartford carry north-bound traffic, going away from Dartford - all south-bound traffic, towards Dartford, travels on the bridge (visible in some shots). No traffic enters the tunnels heading south-bound towards Dartford.
Suggested correction: During times of high winds, the Dartford Bridge is closed, and one of the tunnels does, in fact, carry southbound traffic.
Factual error: When Luke is playing video games in the camp he is using a Playstation controller, however when he pauses the game it shows a message telling him to push the 'B' button. 'B' buttons appear on Xbox games consoles rather than Playstations.
Factual error: When the people of Lilliput find Gulliver's boat, he picks up his cell phone and says he doesn't have any signal but has 11 messages and proceeds to listen to them. If you have no signal at all, you wouldn't be able to check your voice mail.
Factual error: Hockey player Derek Thompson is nicknamed "Tooth Fairy" because he often knocks out the teeth of opposing players. His car license plate reads #1 TOOTH. In Michigan, where the movie takes place, the symbol # is not available for use on a license plate.
Factual error: The Times Square Jumbotron has a ticker-tape message beneath it. Some of the letters have sections missing, presumably to represent broken bulbs. If this is the case, the missing parts would not scroll with the message, as it's only the constant switching on and off of the bulbs that gives the impression of movement.
Factual error: Zuko pulls out a family portrait out of his shirt and the portrait looks nothing like the characters in the movie, they look more like the cartoon characters.
Factual error: After the snake swallows the dagger - it is able to curve its body beyond that which having the dagger inside would allow.
Factual error: When Toothless zooms in and catches Astrid while she's falling, he was moving so fast that he would have pulled her leg out of the socket when he grabbed it, if not totally ripping it off. (01:19:55)
Factual error: A fire breaks out in the hospital due to one of Abby's victims being exposed to sunlight as she's turning into a vampire, destroying that vampire and a burning a nurse to death. Modern hospitals have fire sprinklers, fire extinguishers, etc. and sensors/alarms that the fire would have activated.
Factual error: In the scene where they are in the U.K, a little boy is hit by a van and you can hear the police and medical services coming. The sirens are American sirens which differ greatly from the High Low pitch that the U.k Is famous for and do not fit the scene at all.
Factual error: Sailing ships in harbor always have their sails furled and stowed, not set. All the ships in the city's harbor have their sails set. Would never happen.
Factual error: Quentin steals Adrenaline from an ER crash cart. That would be believable except, I am a nurse, my husband is a paramedic, my father in law is a doctor. Under NO circumstance is a crash cart to be left unattended, they are locked up when not in use. Also, Adrenaline would NOT be in a cart like that, that medicine is locked up. ER crash carts, like what was used in the movie, would only have had a defibrillator, gel for the defibrillator pads, gauze, dressing and first aid supplies, nothing more.
