Factual error: On the Miz's certificate of appreciation hanging on his refrigerator, the words "Department of Defence" are visible. "Defence" is the British spelling of the word defense, and any official U.S. military document with that word would have used the U.S. spelling. (00:14:30)
Factual error: Early in the film, JFK recalls that his older brother was "shot down" in World War II. His brother was actually blown up in an experimental aircraft, a fact that was known to the Kennedy family shortly after the incident.
Revealing mistake: After Alex shoots the intruder in the head, killing him, a couple of shots later you can see his chest slightly expanding and contracting, showing that the actor was still breathing.
Revealing mistake: Robin is running away from company investigators. He comes across a supposed wire link fence. He breaks it with his bare hands, and by the flapping of the open piece you can see it is made with strings not wire.
Character mistake: Spanish headlines are seen. Some of the a's have the wrong accent on them ("å" instead of "á"). (00:45:25)
Factual error: The black Range Rover used throughout the movie has the wrong licence plate. The third and fourth numbers on the plate (UK spec licence plate) are '0' and '9' which refers to the vehicle as being a 2009 spec. The Range Rover used in the movie was discontinued in 2006 and was replaced with the face lifted model which the one in the movie is not.
Other mistake: Barbara and Violet are talking in the car after returning from the funeral and all of the windows are closed, even though great effort was made to convey the fact that temperatures were in excess of 100°. They spend three to four minutes talking in the car and neither even breaks a sweat, when in reality, they could not have sat in a closed car in that kind of midday heat for more than 30 seconds or so without becoming incredibly uncomfortable.
Visible crew/equipment: When Julian follows Chang around the streets, during the second point-of-view shot from Julian's perspective, you can see the distinct shadow of a cameraman with a camera on his shoulder cast on the wall. (00:38:02)
Factual error: It was very nice of the East Anglian Transport Museum at Chappel and Wakes Colne to provide a train for the coder to go home in, and come in to work. The station is even in Suffolk; but of the two lines through the station, one is used by public trains, and the other by historic preserved trains. When the coder gets off her morning train, it is seen passing across points from the museum platform line into the railway museum, rather than continuing up the line to Sudbury, as a public train would. Appropriately, the train is a heritage DMU - a museum exhibit which has not been used on the main line for at least 25 years. So that's three reasons why she's not on a train which actually goes anywhere.
Continuity mistake: At the beginning of the film you can hear a kettle whistling. But when Alvin removes a teapot (not a kettle) from the heat the whistling stops, but when he puts in back on the heat about 5 seconds later there is no whistle. Alvin doesn't remove a whistle cap or turn off the heat. (00:02:30)
Continuity mistake: When they are discussing whose pinkie gets cut off, Vince grabs Craig by the neck and pushes him against the refrigerator. Craig is first shown pushed against the right hand side of the refrigerator, but whenever the camera is on him for the rest of the scene, he is shown standing against the left hand side of the refrigerator.
Character mistake: In the scene discussing the provenance of the mirror, the girl stated that Sherman marched to the sea in 1865. It was actually 1864.
Factual error: Don Jon is set in a New Jersey town. A commercial for Hardee's/Carl Jr's restaurants comes on the TV during a family dinner. These restaurants are not in the New Jersey/New York area at all.
Other mistake: After his wife says she can get him a job with her boss, Frank steps off to the right side of the stage acting unsure of it due to his pride. When he goes there, some sort of blue light suddenly illuminates his body that was not there before.
Visible crew/equipment: When the first car seen in the movie stops, the camera rig can be seen reflected in the hubcap.
Continuity mistake: Emily Smith-Dungy just kicked her bags in the snow. Her neighbour and schoolmate Kat drives by and offers her a ride home. Emily after initially rejecting her help accepts it; the trophy switches hands from the first quick shot to the next. Her scarf is also positioned differently. (00:08:40)
Revealing mistake: Before Derek punches the side of the wall, you can see the weakened area of the wall before impact. Look at the color difference.
Continuity mistake: Juliano and Joaquin are having their pictures taking celebrating the first earnings from their own gold pit. All of a sudden between shots, the photographer loses the cigarette behind his ear. (00:18:50)
Continuity mistake: When Paul Walker bends down to see his wife's body, the clock reads 09:47, however in the next scene, the time stamp on the movie shows 09:30am. (00:13:00 - 00:13:40)
Continuity mistake: When Oscar is on the phone to learn about the location of the job interview in the warehouse district, the paper that was on top of the payphone jumps suddenly in the hand that holds the receiver to his ear, with the phone call already being over. (00:22:25)
