Factual error: All sprinklers going off at the same time in a fire or when an alarm is triggered - they actually go off individually and only when exposed to enough heat.
Common movie and TV mistakes since 25 Mar '21, 16:07
This is a list of mistakes, things done wrong, etc. that happen so frequently onscreen we barely notice any more. 'Movie logic', stupid behaviours, and everything related.
Factual error: When a police officer finds a suspicious powder he or she puts some on his or her tongue and knows straight away what drug it is, in reality the powder would need a lab test to analyse it.
Factual error: When an indoor fire occurs, sprinklers often start spraying in the entire building. In reality, though, only the nearest sprinklers (those who got hot enough) will start sprinkling. This is to avoid unnecessary damage in real life, and to focus the available water on the most needed place.
Character mistake: Soldiers leaving the foldable stocks of their weapons folded, despite knowing that they are going into a combat situation. Particularly affects the MP-40 wielded by the Germans in WWII movies, but also some modern examples like the MP5 and the G36. Automatic weapons are difficult to control at the best of times, there is no reason a trained soldier would deprive themselves of this extra bit of accuracy.
Factual error: Stun guns and Tasers do not knock people unconscious. They are designed to incapacitate by either interrupting motor control or causing pain. Movies and TV shows often show someone is zapped with a stun gun and falling unconscious almost instantly. Electroshock weapons simply cannot be used this way, nor are they designed with this in mind. It is absurd for a spy to use a stun gun as a stealth weapon, the first thing the target would likely do is yell from the pain.
Deliberate mistake: When food is served, little (if any) is eaten - even if people are starving. Instead, the diners play with their food, pretend to be cutting it or getting it onto a fork/spoon, and might raise food to their mouth but not actually put any in (which might be followed by "fake chewing"). Frequently, ONE bite is taken out of a sandwich or slice of pizza and the rest goes uneaten. As a variation, when the family is just about ready to "dig into" a holiday feast, there's an emergency = no-one eats.
Factual error: Films set in or around the middle ages depict horses being the size of modern horses. In actuality, horses during that time period were smaller, closer to modern ponies.
Factual error: When the character holding a gun keeps cocking the slide whenever they are about to get into trouble. Once a weapon is cocked, it's loaded. Every other time the slide, or cocking handle is manipulated, the weapon will extract a round from the chamber and draw a new round from the magazine. Whenever this happens in movies or shows, the weapon never extracts the round in the chamber.
Factual error: Films depicting criminal trials in American courtrooms frequently show the defendant receiving their sentence right after their guilty verdict is rendered. In real life, people found guilty will have a separate hearing to receive their sentence several weeks later.
Factual error: Every time somebody pulls out a Glock handgun a click can be heard. Glocks are striker fired, they have no external safeties that can be manipulated. Glock did make a version with a flip up/down safety for the military procurement trials but Glock lost the bid, and commercially made Glock's have no external safeties which would make a clicking sound.
Character mistake: When kids/teenagers have something urgent or important to tell adults (especially parents), the adults say "uh-huh" but aren't really listening OR do not believe the kids even though they are telling the truth. Adults might view the alleged event as a joke ("The Chumscrubber"), too far-fetched ("Eight-Legged Freaks" and "Dog Gone"), an emotional reaction ("Good Boys"), or due to an overactive imagination, often attributed to watching scary movies ("Home Alone III" and "Diary of a Wimpy Kid").
Plot hole: Despite there being hundreds of witnesses, a villain who assaults someone or commits some other crime are not arrested or sued and are free to just walk away and live their daily lives as if nothing ever happened.
Audio problem: A real-life band will be giving a live performance, but the audio is of the studio recording, such as Rammstein performing "Feuer Frei!" in xXx or Alice Cooper performing "Feed My Frankenstein" in Wayne's World.
Factual error: Many early mystery movies do not consider fingerprint evidence, even though such evidence has been accepted in US courts since 1911 and in the UK since 1858.
Factual error: It's a common thing in shows dealing in law enforcement to see a cop kicking open a suspect's door in one try. Doors aren't that easy to break open in real life. This is why cops in the real world use battering rams or a sledgehammer for this purpose. Even a door that is hollow could lead to the cop kicking his foot straight through instead of forcing the door open, and a door with a solid frame is more likely to lead to the cop sustaining an injury.
Factual error: Chloroform doesn't render people unconscious almost immediately, it takes a few minutes.
Character mistake: A lawyer in an American court will object to part of a witness' testimony and when the judge sustains it, the lawyer does not move for the objectionable testimony to be stricken from the record. In real life, if a judge sustains a lawyer's objection to a testimony, the lawyer will request the testimony be stricken from the record, otherwise it will be fair game for the opposing counsel to refer back to that testimony later in the trial.
Character mistake: Gunmen who follow moving targets with gunfire instead of leading them.
Other mistake: The "latest hit video game" in film and TV productions will often seem very old fashioned, with outdated features like numbered levels, high scores, extra lives, etc.; indicating that some writers have not kept up with video game trends since the early 1990's.
Factual error: Many times in movies, we can see the hero running into a burning building or approaching a burning vehicle to save someone, then escape from the flames with only a few black coal spots on his face. In reality, the extreme heat would make it impossible for an unprotected person to get THAT close to fiercely burning fire. Even if he can overcome his natural instinct, the pain from hot air would be unbearable (it's nearly as excruciating as direct burning) and leave him with severe injuries.

Suggested correction: Not true. Generally they are tasting it to see how pure the drug is. Hard drugs are often diluted with milk sugar, so they make a bigger profit. The higher the sweet taste, the less pure the drug is.

First, law enforcement officers don't ever taste drugs, it's a good way to die if you don't know what you're ingesting. But second, the mistake isn't saying they are tasting drugs to know it's strength or purity. The mistake is explicitly about a cop tasting a drug and positively identifying what it is based on taste, which happens a lot in cop movies. Such as when the cop says "that's cocaine", not "that's half pure cocaine."
