Factual error: The Royal Canadian Mounted Police are shown checking baggage in the final scenes at the same time that FBI agents are making arrests. The flight landed in Goose Bay, Newfoundland and Labrador, Canada. According to the Criminal Code of Canada, any crime committed during an international flight that ends on Canadian soil is deemed to have been committed in Canada. That being the case, the RCMP as the national police force has full jurisdiction. There is no way the FBI would be involved at that point.
Factual error: We are told at some point that Nicole Kidman has dual nationality because she was born in the US. In the final scene, when she is talking with Sean Penn about her future steps, she says she has been deported and given one day to leave the country. She was a US citizen, so it is impossible that she would be "deported".
Factual error: When Angela is watching the security video on her laptop of her sister committing suicide, you can see she's playing it using Quicktime. She rewinds a couple of seconds by clicking on the first button of the video player. Actually, when you click this button, it takes you to the beginning of the video. The second button would have rewound it a short time. (00:25:20)
Factual error: In the shot where the laser sights of the assailants come in through the windows and holes in the wall, their angles are far too different from each other. The shooters are standing at a rather great distance from the structure and at more or less the same height. All the laser sights should have more or less the same direction and certainly not make a sweeping motion inside the room. (00:37:30)
Factual error: When the first train wheel hits the ground in the close up, you can see that it isn't made of steel as it deforms as if it were foam. And there is also no damage to the concrete road whatsoever, since the wheels are made of steel there should have been quite a big hole. (01:17:50)Ronnie Bischof
Factual error: When Marv is talking with the Priest in the confessional, he cocks the hammer of his pistol as a means of interrogation. But in the next shot, the pistol is uncocked, without sufficient time for this to occur. In fact, the pistol is uncocked even when Marv shoots him. This cannot happen, since his pistol is a standard 1911 .45, which requires the hammer to be cocked in order to fire.
Factual error: During the scene in which the plane flies directly toward the ground at a speed of 2070 knots to deliver the bomb, after dropping the bomb and pulling up to fly horizontally through the city streets, there is no damage or anything created from a sonic boom. At that level and speed, the sonic boom would have been tremendous on the ground, even if the plane was designed to minimize the shock wave.
Factual error: The timeline for this film is incorrect. The flight Lisa takes is a red eye from Dallas to Miami. Non-stop flights between those cities takes 2 1/2 hours. Even with the west to east time change, this isn't long enough for a red eye. Shortly after take off, the clock in her father's house reads about 11:15pm. The plane lands after sunrise in Miami.
Factual error: In the final scene with the New York skyline in the background, the new glass/stainless steel Manhattan complex at 731 Lexington Avenue is seen; this building is just being finished now in early '06. The building stands where Alexander's dept store once was. (On a related note, it is a nice touch on Spielberg's part to overlay the Twin Towers onto the skyline in that same scene.)
