Character mistake: Austin is supposed to be the archetypal Swinging Sixties Londoner yet he refers to his car as a Shaguar, a pun on 'Jaguar', pronouncing it 'Shag-war'. A native of this green and pleasant land would pronounce it 'Shag-u-ar', three syllables, not two, based on our pronunciation of the car manufacturer's name: Jag-u-ar. He also refers to a truck - a 'lorry' - as a "law-ree." We call them "lurries."
Character mistake: When they're on the island and the INGen helicopters are flying in, Jeff Goldblum takes the binoculars and looks through the wrong end. (00:32:30)
Character mistake: When Nicolas returns from Mexico and goes to the gate of his house, he sees a sign that says his house is being sold at public auction. The word "foreclosure" is spelled incorrectly. It is spelled "forclosure."
Character mistake: At the meeting of the MVD and FBI where they are discussing Terek's hiding place, she mentions that he's in the town of Porvoo and that it is 60 kilometers west Helsinki. Porvoo is actually 50 kilometers northeast of Helsinki. (00:12:45)
Character mistake: When the police scan Leeloo the first time, the computer reads "Commencin" instead of "Commencing."
Character mistake: When Carver is to go live to the World, his assistant is counting down 5, 4, 3, 2. She does not say 1 and 'Now', as they never do, in order for her voice not to be heard on the broadcast. But if you do the counting, Carver starts before she would have reached 'Now'. Consequently there would be a risk that Carver's first words were not heard on the live broadcast. That would be very unprofessional.
Character mistake: When Harry is registering, he has glasses hanging around his neck and is wearing another pair, presumably readers, while he checks in. After exchanging pleasantries with the proprietor, he takes off the glasses, puts them on the counter, and leaves without them. (00:08:05)
Character mistake: When Gilmore radios for backup during the Monument Valley chase, he is told additional officers will join them in Blanding. Kowalski hears this on his scanner as they pass a sign saying Blanding is 14 miles away. Kowalski then stops dead in the road and turns around, and the troopers do the same, yet when Sgt. Preston grabs the shotgun, he justifies firing on Kowalski saying "We're coming on to Blanding!" In actual fact they would be heading away from Blanding.
