Continuity mistake: When Bullock is warning Reeves of the coming winter blizzard, she is looking through pictures that depicted her and her friends enjoying the snow. She then turns to the dog and asks "Remember that day? You were not happy". However it's revealed that both characters have the same dog, given to Bullock's boyfriend by Reeves, so when the snow happened in Reeves' time - 2004 - the dog was with him.
Continuity mistake: As Dalton stands inside the bank vault staring at the cash, the scene jumps from a wide, distant shot, to medium, to close-in, just outside the cage. Another robber stands just outside and between jumps his gun position shifts from relaxed to raised to relaxed again.
Suggested correction: Whilst this is true, I don't think it is a continuity mistake. It looks to me like it is intended to suggest the passage of time between each of the three shots.
Other mistake: When Jaguar Paw is running to reach the corn to escape and gets knocked down by an arrow; Middle Eye was about to whack him when Blunted intervened. You can hear Middle Eye say in English "Get off me!" while he's being held back. (01:27:52)

Factual error: In the scene where Vince returns to his dorm room and finds Dennis Franks has moved in, Franks informs him that Coach Vermil is mixing the veterans with the rookies. In 1976, Dennis Franks and Vince Papale were both rookies.
Continuity mistake: Right after Queen Latifah hits her head and is having a fantasy, LL Cool J is unbuttoning his shirt. The scene cuts to Queen Latifah and when it cuts back his shirt is buttoned up and his tie is tied properly. It cuts back to Queen Latifah and back to LL Cool J where his shirt is now once again completely unbuttoned. (00:14:00)
Continuity mistake: Watch the newspapers on the front of the bus when Mos Def is getting off. At one point there is a big hole and you can see out, but in the very next shot a newspaper is covering it again.

Factual error: Rescuer and US Marine Jason Thomas is an African-American in real life, but was portrayed in the film as a white man. The film's producers realized the mistake only after production began, and apologized to Thomas, whose identity had not been widely known for years after September 11th.

Factual error: As the two fast boats start heading up river towards the finale shootout, one boat has its navigation lights reversed. It has a red light on the starboard/right side, and a green light on the port/left side. It should be the other way around. (The lights on the other boat are correct.)
Factual error: When Morty is showing Michael how to use the remote, Michael rewinds to a family vacation in 1976. A childhood friend of his invites everyone over to his parents' RV to watch Three's Company. Three's Company didn't premiere until 1977.
Suggested correction: Although technically this is true, ironically there WERE two pilots for Three's Company filmed in 1976 with some similar and some different cast members, which may or may not of actually aired at the time after being filmed. The 3rd and final pilot with the familiar cast got the show finally rolling in 1977. So the mistake stands, but it could be a bit iffy based on this info.
This mistake does not need correction. This is just trivia that does not impact the mistake. Both pilots were unaired, so they couldn't have watched it on TV. Additionally, this was his summer vacation and the first pilot was taped in May and the second one was taped in November.
Factual error: Louis Simo gives his son an Etch-A-Sketch while taking him to school, and later when Louis stops by to see his son at his ex-wife's house, his son is playing with the Etch-A-Sketch in his bedroom. Both incidents take place in the summer of 1959. George Reeves died June 16, 1959, hence the investigation. The first Etch-A-Sketch toys were produced on July 12, 1960 and Ohio Art launched the toy in the United States in time for the 1960 holiday season.
