Factual error: In the movie, when the baby is born and Big Momma delivers it, the baby comes out without any blood and there's no umbilical cord. (00:34:20)
Factual error: In the scene where the FBI agents have taken Giovanni Ribisi in for interrogation, one of the FBI agents says at one point "...and I want the whole C:/ Drive backed up on a floppy.", which is pretty hard to do, if not impossible, unless you've got about a 5Mb hard disk drive (depending on compression levels). But later on in the scene where Ribisi is actually doing it, he does it in about 10 seconds...with a 1.44MB floppy.
Factual error: The film takes place in the Thirties. The song "You are My Sunshine" is featured, but was not recorded by Jimmie Davis (its composer) until 1940. [Acknowledged by the directors]. (00:11:15)
Factual error: Right at the end, Memphis escapes by jumping via a flatbed towtruck. The ramp is put down on those to tow away a vehicle so it should be backed right up to a vehicle to lift it on. That begs the question of why the ramp was down with no vehicles anywhere near it. The maximum distance that any driver would want to maneuver with the ramp down would be a couple of feet straight back.
Factual error: After the attempted kidnapping, Norm Macdonald's face is in the Newspaper the next morning. This is not possible because the crime was committed the night before and not discovered until the very morning his face is in the Paper. There would not be enough time for that article to be written.
Factual error: This movie is supposed to be set in the 80's as it says in the beginning of the movie, however, during many shots where the street is visible from the news broadcast center or the scene with John Travolta in the street, there are many cars which were not around. One of these cars, for example is a 2000 Dodge Intrepid.
Factual error: In the scene where Shaft has chased the guy running from the drug bust and caught him in the hall with an empty gun you can plainly see the slide is locked back on the bad guy's pistol (indicating an empty magazine). When Shaft steps out to arrest him (before the bad guy jumps out of the window into the other building) you can clearly hear the 2 clicks of a firearm hammer falling on an empty chamber. With the slide locked back, the hammer is locked back also...it would never make any clicks.
Factual error: The Ohio Supreme Court does not meet in the State House, as portrayed in the movie. (00:07:40)
Factual error: The actress Sasha Barrese is credited at the beginning of the movie as "Sasha Berrese".
Factual error: Easy to spot. The chocolates are referred to as Belgian at the beginning of the movie, but you can see they are in fact Baci by Perugina (from Italy).
Factual error: Placing a watch over a fresh brand would hurt a lot and they would be adjusting their watches continuously because of the gross scabbing
Factual error: The team are shown using bare, wet hands to drill through and handle rough, steel reinforced concrete. Without gloves on, the skin on their hands would have been shredded and bleeding in a very short time.
Factual error: When Marion picks up the phone to call to score a hit, the number she should dial is 934 8777. However, listen to the pitches of the keys she dials. The pattern should sound like: EECDCCC. The pattern she dials is: DCDEDDD. She is clearly not dialing 934 8777. (01:16:25)
Factual error: When the police are looking at the reflection of a neon sign in the glasses in the picture of the girl, the letters are reversed as you might expect. But the sign is on the glass front wall of the shop, facing the outside. Since the photo was taken inside the shop, the inside view of that sign would have already been reversed, and the reflection should have been the right way round. (00:35:15 - 00:39:40)
