Factual error: Opening scene shows NYC 1962 as a 1964 Chevy Impala rolls by.
Factual error: Rhianna is watching a live feed of a man's office via webcam. We see a closeup of the screen. At the top it shows the filename being a ".jpeg." Jpegs are still image files, not movies, let alone live streams.
Factual error: The country of Pakistan was shown to be part of the G12 summit member countries. But the G12 are Australia, Belgium, Canada, France, Germany, Italy, Japan, Netherlands, Spain, Sweden, Switzerland, the UK and USA. (13 countries, but the name was never changed when Switzerland joined in 1984).
Factual error: The opening scene shows Donna graduating from New College in 1979. That is not possible, women were only first admitted in 1979.
Factual error: In the second-to-last scene, Rachel is leaving Singapore for New York. Nick goes onboard to propose and convinces her to stay in Singapore for one more night. However, this is not possible in Singapore due to strict laws which state that those who enter the departure area must have a boarding pass and intend to leave the country. Those who have a boarding pass but no intention to depart will be prosecuted. In 2018, 40 people were arrested for various offenses, such as sending a friend off or meeting their idols.
Suggested correction: Nick's family is extremely rich, powerful and famous in Singapore. That might have been enough to get him special treatment or an exception to the rule.
Factual error: While bidding on eBay for the steering wheel, Vanelope tries to up the $350 bid by bidding $1,000. This scares off the real bidder, but Ralph and Vanelope don't understand how eBay works and bid against each other until they win with a $27,001 bid. That's not how eBay works. Vanelope's initial $1,000 bid wouldn't have set the high mark, but would simply have been her maximum bid in case the other bidder kept increasing his bid. The current high bid would have increased by the increment amount until it reached Vanelope's max bid. Now, it could be that the system recognized Ralph and Vanelope as separate bidders and that's why it let them keep upping the max bid. But, if the system had responded normally and simply increased Vanelope's bid to $355 with a max of $1,000, they might have realised what was going on and not started bidding randomly.
Factual error: The rabbits are underneath the landrover, and they get shot out the back whilst holding on to the axle. Land rovers have an enclosed axle with a hub enclosing the diff, so this would not be possible.
Factual error: Right at the start of the film, it shows the girls going up for the first day of school which would have been around Fall. It shows tulips blooming in the garden, but tulips only bloom during the spring. (00:00:55)
Factual error: Jonah Hill references "Chucky" from the movie Childs Play. This movie's period is set somewhere in the late 1970's. The movie Childs Play didn't come out until 1988.
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: 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: 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: In the bar scene there is a sign for Genesee beer. That brand never went west further than Pennsylvania.
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: 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: 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: 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: "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: The female Frankenstein tries to set Dracula up with during the wedding reception is referred to as his "right arm's cousin" but the big arm that looks like Frankenstein is her right arm. (00:08:10)
Suggested correction: Frankenstein wasn't saying she had the other half of his right arm (i.e. his left arm), just that the 2 arms came from 2 people who were cousins.
