Factual error: In the scene where Billy's brother argues with a miner in the local shop, there is a plastic Polo dispenser that wasn't around in 1984.
Factual error: In the scene when everyone is in the white Hummer, the vehicle is moving north on the Las Vegas Strip; on the right is Bally's and the Flamingo, with Treasure Island straight ahead in the distance. Yet a few seconds later, when Joy asks the driver to let them out, they are in front of the fountains at Bellagio, which indicates that they are now travelling south on the Strip - yet we never see the Hummer change direction or turn around.
Factual error: When Howard is running after the bouncy ball he is on the second floor of the Mall of America, however, you see him run through the LEGO store which is located on the lowest floor of the Mall of America, which is impossible if he was on the second floor before.
Factual error: When Morty is showing Michael how to use the remote, Michael rewinds to a family vacation in 1976. A childhood friend of his invites everyone over to his parents' RV to watch Three's Company. Three's Company didn't premiere until 1977.
Suggested correction: Although technically this is true, ironically there WERE two pilots for Three's Company filmed in 1976 with some similar and some different cast members, which may or may not of actually aired at the time after being filmed. The 3rd and final pilot with the familiar cast got the show finally rolling in 1977. So the mistake stands, but it could be a bit iffy based on this info.
This mistake does not need correction. This is just trivia that does not impact the mistake. Both pilots were unaired, so they couldn't have watched it on TV. Additionally, this was his summer vacation and the first pilot was taped in May and the second one was taped in November.
Factual error: If we are to assume the film is in chronological order over the course of a single school year, then why does the football scene come after Christmas has occurred? High school football season ends well before the holiday season. (00:47:00)
Factual error: There is a scene with several flags hanging on the wall of the castle. These are supposed to be flags in the Middle Ages. However, one of them is the present day banner of the Hungarian Republic (where part of the movie was shot).

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: In one of the first major scenes where Matt Franklin and Tori Frederking are being introduced at the rental store - there is a shot where you can see the entrance of the store, and there is an electronic article surveillance detector on either side of the entrance to the store. This technology for use in a video rental store (for VHS tapes) did not exist in the 1980s.

Factual error: When Tom calls Hannah from New York (and she is in Scotland) there is still bright daylight in New York. When Hannah answers she says it is 3am in Scotland. With a time difference of only 5 hours, this would mean it would be 10pm in New York and therefore dark.
Factual error: At the start in 1989, when Mike is dancing with the cheerleaders and also just before he goes after Scarlet, in close-ups of the crowd cheering there is a man (with a white baseball cap) wearing a Paramore t-shirt. However, Paramore (a Grammy-nominated American pop rock band) formed in 2004. The style of t-shirt he is wearing is actually one of the officially licensed Paramore merchandise. (00:02:45)
Factual error: In the scene where Mystery is playing "Rock & Roll All Nite" in the basement, Hawk is playing an Epiphone Special II guitar. The movie is set in 1978, and this guitar did not hit the market until 1996.
