Factual error: The interior shots of the Gemini and Apollo Spacecraft show worn and dirty panels, knobs, switches and circuit breakers. The movie most likely used some original cockpit trainers, but in reality the astronauts were flying brand new spacecraft that were spotless.
Factual error: In a scene in 1980, Brian May is teaching everyone the beat for his new song "We Will Rock You." However that song was released in 1977.
Factual error: There were no black paratroopers on D-Day or in the 101st, nor were white and black soldiers serving in the same unit.
Factual error: The repairman was freeing the soldiers from inside the locked gate using bolt cutters. The terrorist noticed this on the video feed so they electrified the fence, shocking the repairman. This would not have happened because the bolt cutters have plastic handles just for that reason, to keep you from being electrocuted by mistake. (00:54:50)
Factual error: Towards the end of the movie when Ally is in her hallway looking at Jack's old concert tour posters hanging on the wall, the poster closest to the camera says "Washington State Fair" and a 2011 date. Unfortunately, that fair did not get that name until 2013. Before that, it was called "The Puyallup Fair" (officially named the "Western Washington Fair"). Locals still call it "The Puyallup Fair" to this day.
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: In the second last scene, when Rachel is leaving Singapore for New York, Nick went onboard to propose, and convinced her to stay in Singapore for one more night. However, that's not possible in Singapore as there are strict laws stating that those that enter the departure area must have a boarding pass, with the purpose of leaving the country. Those that have a boarding pass but have no intention to depart the country will be prosecuted, and in 2018 40 people were arrested for various reasons, such as sending a friend off and meeting their idols, etc.
Factual error: Grain engulfment is not depicted in a scientific manner. It is not possible for engulfment to happen without a valve being opened at the base - which has not been shown in the movie when the boy falls in the grain storage. It is very unlikely that two engulfments will happen so close by in the same storage - if so, they will converge quickly. But, the movie shows both victims help each other one by one. They succeed in 5-10 seconds. Engulfment become entrapment in less than 20 seconds and require more than thrice the body weight to pull some one out (unlike one kid being able to pull other one out while both are on the grain). Finally, they both sit on the door and avoid entrapment.
Factual error: Lori takes a screwdriver to the left hand side of her abdomen. The doctor says it just missed her liver and she has lost a lot of blood. The liver is on the right side of the body and nowhere near where she took the injury.
Factual error: 3 plutonium balls would weigh 180 kg, each one 60kg, they wouldn't be able to single hand it, not to mention throw a suitcase with 3 of them inside. Critical mass is 11kg for ball shape so they wouldn't be even able to make those balls.
