Factual error: The bad guy's henchwoman reads the license plate as "SI52JGN", he repeats it as such but on screen he types "S152JGN" (with the second character as a number 1 and not a letter I). I (like Q and Z) is a letter that can't be used in the first 2 digits of a UK license plate, anyway. (00:04:45)
Factual error: Jerico is transported from Hazelton penitentiary, West Virginia, to the Air base in Delaware, on a helicopter with a registration number starting with G, therefore a UK aircraft (where the movie was actually shot). (00:14:00)
Factual error: Showing the submarine Strook "hacks", the movie displays "USS Virginia SSN743." USS Virginia is SSN774, while SSN743 is USS Louisiana. (01:13:10)
Factual error: The villain performs his hit at the beginning of the movie by remotely changing the GPS destination of a cab, so they head to the wrong place and into an ambush. Assuming that neither the cabbie or Pope notice the change on screen, and that his sophisticated software silenced the voice announcement of the course being recalculated, and makes the new place also marked as the old one (it is after all a god-like movie software), the trick is done on on a London black cab, whose drivers are notorious for "The Knowledge", aka being required to learn the entire topografy of the city in one of the most demanding training courses in the world, and not using GPS. It'd be definitely unlikely for the cab driver to be totally unaware, to the point of Pope himself noticing first that they are at the wrong place.
Factual error: Jan Strook is a Dutchman; throughout the movie he is referred to as "Jan Strook", which rhymes with "took," when it should rhyme with "broke." This is even worse considering he has a Dutch accent in the movie, which leaves him no excuse for mispronouncing his own name.
Factual error: When Kevin Costner plunges off the bridge in a taxi, he cuts his leg on a piece of the door side glass. This is impossible as all side windows are made of tempered glass that completely shatters, leaving no sharp pieces that could cut.
Factual error: When the helicopter arrives at Dover AFB carrying Jericho, the controller states runway 22L. Dover AFB has intersection runways 1/19 and 14/32 and no parallel runways.
