Character mistake: When Charlie is calling out the brick count to Napster from the subway, he describes it as being "13 across, 4 high, 4 deep". The bricks appear to be 2 deep in the safe (13x4x2), so he could just be lumping two shelves together, which works (13x4x4 = 13x4x2x2). The problem is that when the camera pans down there are 3 shelves in the safe. This means that there are more than the 208 bricks that Napster announces. (01:33:40)
Character mistake: In the opening scenes when Brian goes back to the shop, he demands that he needs some nitrous to boost his low top speed. Well I'm sure that most tuners will agree that more horsepower doesn't equal more top speed, it only contributes IF you have a transmission that can handle it and distribute it. (00:09:53)
Character mistake: When Mike and the SAS team leader first meet, the team leader introduces himself as Will Davis, Captain. However at the near end when they say goodbye to each other, Mike addresses him as Lieutenant. (01:07:35 - 01:25:35)
Character mistake: Austin is supposed to be the archetypal Swinging Sixties Londoner yet he refers to his car as a Shaguar, a pun on 'Jaguar', pronouncing it 'Shag-war'. A native of this green and pleasant land would pronounce it 'Shag-u-ar', three syllables, not two, based on our pronunciation of the car manufacturer's name: Jag-u-ar.
Character mistake: Tej mentions that the BMWs they used were factory-line, ie. unmodified. Hobbs then says that they were twin-turbo V8s "spitting out 560 ponies". The BMW M5s they have are E60 models (2005-2010) powered by a naturally aspirated 5.0 liter V10, producing 507 horsepower. (00:38:30)
Character mistake: The police claim the Myers house is at "45 Lampkin Lane." The address on the front porch clearly displays the number 709.
Character mistake: At the very beginning of the film, when Hannibal Lecter is serving dinner to his guests, one diner asks "what is this divine looking amuse-bouche" when she and the other guests have a full plate of food. An amuse-bouche is a single bite of food meant to be served at the beginning of a meal, not a plate full of food. Lecter's guests would be better educated.
Character mistake: At the end of film when the Chinese refugees are being unloaded from the lorry a policeman helps an injured man off, then goes back to help others. The injured man sits and then lies down. As he does, the policeman that helped him throws a bag without looking, which hits the injured man.
Character mistake: Dave's wife refers to McCall as his "Army buddy" - but the pictures in McCall's house on the shore show him to be a Marine. Not a generalisation a Marine would make.
Character mistake: Watson says that there are fifteen windows on the front of 221B Baker Street, but if you look, there are only twelve.
Character mistake: In the beginning of the film, Oliver has been brought by Mr. and Mrs. Bumble to the Governor's door after asking for more to eat. Mrs. Bumble then sings, "They'll lay the blame on the one who named him," and as Mr. Bumble is responding, "O-li-ver", look at Oliver. He is completely spacing out and not in character at all - staring off into the distance and flicking his tongue in and out of his mouth.
Character mistake: In the scene showing the outside of the hotel the British flag is flying upside down. The wider white band on the white X has to be top left next to the top of the flag pole. It is at the bottom, which is a universal distress sign.
Character mistake: When Spencer Tracy is talking to his wife and daughter on two separate telephones, he places the phones up against each other so mom and daughter can talk to each other. One phone should be upside down so it would be speaker to transmitter rather than speaker to speaker.
