Factual error: When the Betty Doll takes off, there is a rapid fire selection of different shots of how the craze is impacting the nation. During the baseball scene, the shot starts with a L.A. Dodger (Eric Karros) hitting a pitch from a New York Mets pitcher (appears to be John Franco). The shot changes to that of the baseball going into the stands... in Wrigley Field, home of the Chicago Cubs.
Factual error: This movie takes place in 1990, but that big 'Welcome to Daytona Beach' sign was not built until 2001. (00:21:05)
Factual error: When Gantz fires Nolte's gun at Nolte, he fires 8 bullets out of a six shooter. (00:18:45)
Factual error: In the final race, they are able to slow down and stop two extremely powerful machines, travelling at well over 100 miles per hour, on a dirt road, in a very short distance. In reality, they would have gone through the wooden arch over the road, through the white fence, and ended up halfway up the hill in the background, amongst the horses.
Factual error: In the scene where Shaw is talking to a goon while fixing his car he states the simplest things cause the most problems while holding a spark plug. We know this can't be right as Brian concludes the car is a turbo diesel like a Le Mans car, which would actually use a glow plug and not a spark plug. (00:19:50)
Factual error: In the scene depicting life on Baker Street (after the "Sherlock Holmes" title), a horse-drawn carriage races through the streets of London. The only problem is, the carriage is driving on the right side of the road with others passing on the left. In England, carriages would be driving on the left. (00:07:05)
Factual error: The scene where Nightfox steals the Faberge Egg is all wrong. A laser security system must have a photoelectric receptor at the other side to detect if somebody pass between the two devices. As shown in the film, the laser beams points everywhere, so the system can't work and somebody could cross a beam without starting the alarm. Even if it was some weird system based on measuring distance it wouldn't work - if the laser hits the floor at an angle it won't bounce back to the source, it will reflect towards the ceiling.
Factual error: During the first race a square plate on the floor falls off Brian's Eclipse. The Mitsubishi Eclipse is a unibody car; the frame and body are built as one solid piece, and it does not have floor pans. While some racers might put a steel plate in the interior as a finishing piece, it would be cosmetic only and not part of the vehicle's structure.
Factual error: During the custody hearing, the Maryland flag in the courtroom is upside down. The rule for a Maryland flag is "black and gold, top of the pole," this flag has the red symbol at the top.
Factual error: The Saint steals gold. One gold bar in this movie measures 30cm x10cm at the base and 7 cm high with a 10 degree draft angle. That means about 2.1 liter size and weight of 40 kg for one gold bar. The Saint moves bars with one hand from the briefcase to the backpack, can run and hit etc. The backpack would weigh 240kg and somehow a man runs off with it one one hand. (00:07:00 - 00:11:50)
Factual error: Opening the blank envelope, Marta finds the fragment of the toxicology report. It is signed "Office of the chief medical examiner, Norfolk County, Massachusetts." But then it writes also the address of said office, which is in Marlborough. Marlborough is also the city when Marta resides, and where the lawyers' letters we see come from. But Marlborough is also a city in the Middlesex county, not Norfolk. (01:28:25)
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.
Factual error: Lord Rama is shown holding the bow in the right hand and raising the left hand for blessings. In Hindu practice the blessings are always given by right hand.
Factual error: During the chase with the semi, McClane is shown struggling to keep the truck under control with the freeway collapsing/blowing up all around him. He is shown making a left turn on a ramp, and the truck going up on 9 wheels, almost rolling. The shot cuts back to McClane steering left to to try to control the truck. If he were to steer left, as depicted, he would be guaranteed to roll the truck. If he was trying to get the wheels back down, he'd have to steer into the roll, or right, to bring it back on the wheels. At the end of the shot, you can actually see the stuntman brings the wheels down with a short right turn of the steering wheel. The similar entry in corrections is right, the person making the correction is wrong. During 15 years of driving a semi, I had a very similar situation with the truck almost rolling. I had to steer into the roll to bring the truck back on the wheels, not away from it, as the film showed McClane doing.
Factual error: In the scene at Idlewild airport, the actors walk past the rear of an easily identified 1965 Chevy Impala. Occasionally Chevrolet introduced vehicles early, but never two years early.
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.)
