Factual error: When Zach and Nomi are talking on stage after Nomi's disastrous experience at the boat convention, Zach places a call to Phil Newkirk. There are several problems with the call: the cell phone doesn't appear to be on (he raises the antenna at the beginning and end of the call, but he never presses an "on" or "off" button); Zach doesn't punch in enough numbers for the call to appear legitimate (too many numbers for speed dial, but too few for a local seven-digit phone number [also, since he was using a cell phone it's unlikely that he dialed a hotel extension number]); and the pauses between his words and Phil's response on the other end of the line are too short to be believable.
Factual error: Throughout the movie, all sorts of messages are passed over the 1MC (ship's intercom) when the boat is supposed to be stealthy. They've set "Ultra Quiet" to avoid the enemy sub but no-one was any quieter, and everyone was still using the 1MC. Worse, people are shouting commands and status updates, both in person, and over the intercom! No wonder that Akula found them. The only thing protecting this ship was plot armor! In real life, messages would be passed quietly using sound powered phones (which we also see), rather than blasting the info loudly to the entire crew, because sonar will literally pick up the sounds of loudspeakers and people shouting. Let's not even mention classified target data being passed to the entire ship's crew on the 1MC. (00:49:00)
Factual error: The suits worn by dangerous disease researchers would definitely never tear if the hose was pulled.
Factual error: When Lovell's daughter is complaining that the Beatles have broken up, she slams the album Let It Be into her rack. The scene takes place on the day of the initial explosion aboard Apollo 13, April 13 1970 - immediately prior to the Lovell family attending the screening of a television broadcast from the spacecraft. Let It Be was not released as an album until May 9th, 1970. In April Ringo was still recording drum tracks, not even possible for an advance copy to get out.
Factual error: When the porter first gets ready to shoot at the terrorists (after Ryback falls off the train) he goes through a series of verbal instructions to remind himself what to do. The very first thing he says is "safety off". The problem is that the gun he is using is a Glock pistol. Glocks use a device called a "safe-action trigger" but they don't have a manual safety that you turn on and off.
Factual error: Princess Isabella was a 13-year-old girl living in France when William Wallace was executed in 1305. She didn't marry Prince Edward until 1308, and the marriage took place in Boulogne, not London.
Factual error: A person with 60% burns on his body would not be wearing pyjamas, as the Hungarian guy does. (00:19:45)
Factual error: Near the end of the movie, as the money train is approaching the passenger train, the motorman is communicating on the microphone with dispatch. If you notice, as he is talking, his hand is NOT on the throttle. On the trains in the NYC subway system if the throttle is not depressed the train will stop.
Factual error: You hear Richard unzip his pants when he sees the woman diving into the pool, but even before he goes to the window he is wearing boxers. Boxers are all buttoned, they don't have zippers.
Factual error: Roberta has a Meet The Brady Bunch record on her desk. The release date for this record was 1972, yet this film is set in the summer of 1970. (00:12:55)
Factual error: In the jewelry robbery montage, Joe Pesci is shown holding a rechargeable Mag-Lite flashlight which would not have been available at that time.
Factual error: The roads show only two wheel tracks, there is no wear on the center of the road, from either horses or oxen. Most pre-auto movies miss this.
Factual error: Almost at the end of the film, Poncelet is marched to the death chamber, with Prejean's hand on his shoulder. They are led past an open door - which leads to the viewing room, where the witnesses will congregate. Some of them are already in the room. This is nonsense - it is inviting a bereaved relative to attack the condemned man. In fact the corridor to the death chamber goes nowhere near the witnesses' area, and Prejean would have had to have been escorted back through two guarded doors to reach it.
Factual error: Not only is the tractor the wrong vintage, it is pulling a round baler that wasn't invented until the 1970's.
Factual error: At the ball, in 1957, they play Eddie Cochran's "C'Mon Everybody" which wasn't written until 1958.
Factual error: The Smokers' plane is shown with every surface completely rusted reddish-brown. But planes are made from light alloys, not steel. They can eventually corrode - very slowly - but the film of corrosion is white, not red like iron rust.
Factual error: When Arthur marries Guinevere, the altar is decorated with yellow hybrid tea roses. Hybrid teas were not developed until the late 19th Century; yellow ones would not have been available in England until approximately the 1950s.
Factual error: When Van Damme goes on the ice to play Brad Tolliver he punches the player with number 22, which actually was the number of Christian Ruuttu, but the player who got hit is called Dupinsky afterward.
Factual error: As Al Pacino is catching up to Robert De Niro on the freeway he uses his walkie talkie to get an update on De Niro's location. He does not take his finger off of the talk button and therefore would not be able to hear the helicopter pilot's response.
Factual error: John Smith's (voiced by Aussie, Mel Gibson) accent changes and also fades in and out during the course of the movie.
