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: 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: 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: 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: 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: When Buster joins the card game in the saloon, he looks at the hand of the player that had just left. Given the circumstances in the saloon, the cards cannot be spot clean and white as fresh snow. Also, they seem to be plastic cards, which did not exist yet back then.
Factual error: Sherman prints a gun through the hospital's 3D printer. We see the gun, the cylinder, and 6 bullets. But if bullets are printed too, they still would need to contain the gunpowder, and the 3D printer construct shown there looks made out of a single kind of material, plain looking, surely not the product of a wonder machine that'd be able to recreate the complex chemistry required to make working bullets it was not even designed to do - in fact they look like suppositories, with no division at all between primer, casing, etc.
Factual error: "Polis" is written on two police vans outside the Stockholm bank Taj (Ethan Hawke) is robbing, but police in Sweden are "polismyndigheten" or commonly known as "polisen" (the police). The word "polis" actually means "city." Also, police in Sweden have traditionally used Volvo cars or wagons, not mini vans. (00:13:03)
Suggested correction: Actually all police cars in Sweden have the word "POLIS" on them.
Suggested correction: This is a picture from the event in the movie.

Not just Volvos.
Factual error: Dr. Irwin is picking a lock. He only inserts a pick and not also a tension wrench. You need both to pick a lock. (00:20:30)
Factual error: Simon receives an email notification at the dinner table from Blue on his cell phone. The cell phone screen indicates that the time is 3:20, which is inaccurate for a mealtime because it is already dark outside and crickets are chirping when he excuses himself to go outside to get some air. (00:28:10)
Factual error: Spoiler! The cultists burned Mandy alive by wrapping a sleeping bag around her, putting gas on her and hanging her from a metal swing set and setting her on fire. After Red frees himself later and craws up to her remains, it's shown that she is barely a pile of ash with her skull still somewhat in shape when he picks it up. It then crumbles into just ash showing she had been fully burnt to the very center. This would not have been the case with how they burned her. Their was nowhere near enough heat or kindling to keep her body burning long enough to turn completely to ash with no remains like that. She would have died, yes, but would have mostly stayed intact as a single body burnt very bad. Bones, features, charred organs would still have been left behind. (01:04:00)
Factual error: You can't detonate C-4, or any plastic explosive, by shooting at it. It's made to only be detonated by a smaller explosion (a detonator). (01:27:05)
Factual error: In the police shoot out scene, you can see that the plate carriers the actors are wearing are really empty. Brolin sticks his hand into Forsing's vest after he was shot, the vest easily folds away. You can also see in various shots how theirs vest bend with their bodies, in a way they wouldn't if they had plating in as they should to protect from bullets.
Factual error: The robbery flashback scene is at least 15 years previous to the main story, placing it circa 1953. The big lettering on the armored car uses Helvetica font, which did not exist until 1957.
Factual error: The vehicles in the convoy are supposed to be armored since the bullet fired by 50 BMG was absorbed into the glass. First off the vehicles are standard, not up armored since the windows are standard factory and not thick ones used in up-armored cars. The highest rated armored car is B7 which will stop armor piercing not 50 BMG. Also, the windows completely shatter after being shot out; armored windows will never shatter, they stick together and chip off. (00:03:00 - 00:05:00)
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: Second scene, caption says "1977 southern California" but she's driving a white 90's Oldsmobile Cutlass Ciera Fwd station wagon.
