Factual error: When Elastigirl receives her new bike she discovers it's electric. Later, when she is rescuing the train, the bike hits a mountain and is destroyed in a fireball. What is making the fireball? It's electric so there is no gasoline/diesel to make a fireball, and a lithium explosion doesn't look like that. (00:33:30)
Factual error: The 7 barrels Wade is on are only 55 gallon drums, totalling 385 gallons, not the 1200 he states. He is also on kerosene, which is not high octane fuel and burns way more slowly than shown. (00:01:53 - 00:02:37)
Factual error: They are filming in Brussels and the leaving Mercedes 190 has indeed a Belgian license plate. But it is a fake plate that has a mistake... It shows 1-N82-63X but a license plate in Belgium has always a combination of 1-xxx-123 where the first part always has letters and the second part numbers. Numbers and lettters are never combined. Also it is missing the mandatory sign to prove authenticity. (00:48:30)
Factual error: The plane used in the film to take Juliet back to London towards the end of the film is a replica of a Dakota C-47. She is painted with black and white "invasion stripes" on both the upper and lower surfaces of the wings - approved in May these were only widely put into use for D-Day in June 1944. After one month the upper surface stripes were ordered removed, and by the end of 1944 they were ordered completely removed. By 1946 when the film is set they would have been long gone from any serving aircraft still flying.
Factual error: The movie is set in Van Diemen's Land (now Tasmania) in 1825. Throughout the movie, in scenes where Clare talks to the aboriginal tracker, Billy, subtitles state that they are speaking in Palawa Kani. Palawa kani was developed in the 1990s by the language program of the Tasmanian Aboriginal Centre, more than 165 years after the movie.
Factual error: Though the movie is playing with historical events for "laughs," it should at least be pointed out for the record that Queen Victoria died in 1901, and the Titanic didn't launch until 1912 (and its construction didn't even start until 1909). So, obviously, there's no way Victoria could have toured it before its maiden voyage. (And the movie acknowledges that it's supposed to be THE Titanic since it shows Moriarty reading a newspaper reporting that it sank, to say nothing of the Billy Zane cameo).
Factual error: In the bar scene there is a sign for Genesee beer. That brand never went west further than Pennsylvania.
Factual error: Max could not have been accidentally shot when Annie drops the revolver. She dropped it when she was startled by firing it into the ceiling so the hammer would still be sitting on the spent/empty shell casing. The trigger or hammer must be pulled back in order for the cylinder of a revolver to rotate to the next live chamber.
Factual error: When Mary and the children go to the bank the long shot of the bank shows a statue that was not erected until 1994.
Factual error: Stan's wife Ida says St. Petersburg, Russia, is a nice place to visit. The city's name did not change from Leningrad to St. Petersburg until 1991.
Factual error: Grace was supposedly a captain in the Marines and a dog handler. Dog handlers in the Marines are not officers. They are junior enlisted personnel (E-3 through E-5). Also, they must first hold the Military Police MOS (Military Occupational Specialty) (5811), after which they may add the Military Working Dog Handler MOS (5812) as a secondary MOS.
Factual error: When the saturation divers open the outer hatch on Kursk, they drop a glow stick. When they do, it falls to the floor on the submarine, indicating the inner hatch was open. The inner hatch of Kursk was closed, later opened by an ROV.
Factual error: The police officer that shows up does two stupid things in a row that real police would never do. When investigating a kidnapping, he calls in what the car was they were looking for. Which he sees. Instead of calling for back up, or even mentioning to dispatch that he found a car that looks like it, after coming from a murder scene at a gas station and following a map left behind to this spot, he approaches the car alone, without calling for back up, or drawing his weapon. Shortly thereafter, he finds the kidnapped boy inside the car, who tells him the man who took him is in the house. The officer then proceeds to go into the house alone to look for a dangerous kidnapper without waiting for backup, even mentioning to the kid that his partner is on the way. (00:32:00 - 00:33:35)
Factual error: The gazette clipping at the beginning of the movie where Velma wrote her disdain for Carol is dated Thursday, March 25. Neither year when the story could be taking place based on other hints had March 25 happen on a Thursday. (00:03:50)
Factual error: When Connor is describing his 1970 LT-1 Corvette,, he says "Holley and Rochester Quadrajet carb." Those are two different brands of carburetors. (01:05:39)
Factual error: Cat Rivers is flying the R44 helicopter from the left seat. The R44 is a single pilot helicopter fitted with dual controls. Two collective levers may be installed (the left is removable) but the cyclic control is not of a conventional nature. This comprises a central stick terminating in a pivoting T bar, which only allows one of the pilots at any one time to control the cyclic with the hand grip in the 'normal' position. The R44 is normally flown from the right seat; it is possible to fly from the left seat and instructors regularly do so. Students and low experience pilots would normally only fly from the right seat, and are discouraged from flying from the left seat when with friends. This is because of the unusual cyclic control configuration and, to some extent, the different instrument scan and visual references for hovering when flying. (00:14:40)
Factual error: Second scene, caption says "1977 southern California" but she's driving a white 90's Oldsmobile Cutlass Ciera Fwd station wagon.
Factual error: Three men are having beer one night in the woods. One man says he has a picture of a girl he took the previous Tuesday. When he goes to get the picture (which would be on his phone), he complains that he can't show it because there is no signal reception. You don't need a signal to show a photo you took on your phone. (00:07:10)
Factual error: The opening scene shows Cassie and Bryan booking their holiday on a laptop. The dates that they book the holiday home are between May 5th 2018 and May 12th 2018, which means the movie is set in 2018. But later in the movie, when Cassie finds the video of Bryan with the two women on his phone, the date is listed as "Sunday, May 7", and May 7th 2018 was a Monday, not a Sunday. (00:01:05 - 01:10:55)
Factual error: Wilde and Bosie meet at a railway station that is just signed "Rouen." There were then two main railway stations in Rouen: Rouen-Rive-Droite and Rouen Saint-Sever (or Rouen-Rive-Gauche). Neither would have a sign saying just "Rouen."
