Common movie and TV mistakes since 21 Aug '19, 00:00

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: Most ventilation ducts are not large enough for a person to crawl around in, and any duct large enough for an adult to fit in wouldn't be able to support the person's weight. In the rare event that a company could afford a large ventilation system that could support a person's weight, they would likely forgo it anyway, as it would pose a security risk.

Suggested correction: Generally, people aren't thinking too forwardly or rationally when someone they're pursuing is about to get away. Their lizard-brain just thinks "getting away -> chase," not considering how unlikely (though not impossible) it is for them to either catch up with the car before it fully accelerates or when it makes a turn, then either pull the driver out of the car or jump on the car.

The person acts on instinct. Many people would do the same in real life.

Catwalk

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.

Deliberate mistake: You don't automatically get "one phone call" when you're arrested in the USA. Depends on the state, for a start. You're always entitled to access to a lawyer regardless, but not always making the call yourself. If you make a call with no-one answering, you've not "wasted" your call either. Plenty of states allow multiple calls, within reason. It's a plot device, not based in reality.

Other mistake: When someone is working on a car or changing a wheel they always manage to keep their hands clean.

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.

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.

stiiggy

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."

Bishop73

Other mistake: A common error for Batman films, despite Gotham City being a large and heavily populated city akin to New York or Chicago, Batman never gets stuck in traffic. In fact, whenever Batman is shown driving through the streets of Gotham, there is little to no traffic at all.

Phaneron

Deliberate mistake: Characters who are being confined in an area (typically inside cages, prisons cells, et cetera) that provides enough space for the character to escape, but they still consider themselves stuck (e.g. the iron bars of a cage/prison cell having enough distance between each other to allow the character to squeeze through between them). This is more common in cartoons and animated films.

Rassdyt

Factual error: An oft-repeated myth in movies, usually in the science fiction genre, is that humans only use 10% of their brains. The truth is that humans use all of their brains, even when asleep.

Phaneron

Revealing mistake: People playing video games in a movie or TV show will often mash the button in a way that doesn't match what is going on in the game.

Character mistake: The victim will wait for the antagonist to finish a speech or villain song, rather than attempt to kill them while their guard is down. It's only the hero unexpectantly bursting in that won't wait for them to be done.

Other mistake: Characters swapping clothes with others suddenly (strangers, police officers, females, etc) always get their size and the clothes fit perfectly.

Factual error: IP addresses are 4 groups of up to 3 numbers each, maxing out at 255 - it's a fundamental limitation of the technology. But IP addresses in movies are often shown as something like 564.100.432.165, which is impossible. This isn't like movie phone numbers all starting with 555, because that's still a feasible phone number, just with a "movie" area code.

Factual error: In almost every movie from the introduction of sound on to present day, lightning and thunder happen simultaneously, while in reality there's always a delay between the former and the latter.

Suggested correction: Hardly always, if the lightning hits right in front of you you hear the thunder immediately. I'd say from about 100 meters you perceive it as instantly, as it's only 0.3 seconds between flash and thunder.

lionhead

This is a mistake about in almost all movies, not in all thunderstorms. The common mistake in the movies is when lightning isn't hitting 100m away from the character, but the sound is still instantaneous.

Bishop73

I assume it's about thunderstorms in movies. Name an example.

lionhead

Instant thunder (even at a considerable distance of miles from the lightning or explosion source) is, indeed, a common and probably deliberate error in most films. The reasoning for it is simple: a prolonged and realistic delay between lightning and thunder could change a 1-second shot into a 6-second shot, for example, compromising the director's intended pace and mood for the scene. Steven Spielberg films have utilized both instant and delayed thunder. In "Close Encounters of the Third Kind," for example, when the UFOs zoom out into the distant background (certainly miles away) in a wide landscape shot, they produce a lightning effect in the clouds that is simultaneously heard as thunder. But in "Poltergeist" (a Spielberg film directed by Tobe Hooper), there is a very deliberate scene of characters realistically counting the seconds between distant lightning and resulting thunder. Choosing to obey physics or not is a matter of the director's artistic license.

Charles Austin Miller

I posted this while I was watching Death in Paradise, episode 7 of the third season, but really, you have never seen in pretty much any horror or cheap slasher movie whenever there's a storm, the flash of a lightning coming at the *same* time as a thunder jumpscare sound? It's vastly spoofed, even, when some ugly/creepy/terrifying character makes its appearance. One example randomly picked? Dracula by Coppola, in the first 10 minutes, carriage, lightning in the distance, not even a split second after, rumble. In RL it would reach you a couple seconds later. But really, it's such a movie archetype, I am sure you can find it in any Dracula movie.

Sammo

The Dracula example doesn't really show how far away the lightning is, it could right above them. It's fake as hell, I agree with that, but the fact there is lightning and thunder at the same time without actually seeing the distance is not a mistake to me. It's also highly unnatural lightning as it only happens twice and then nothing, it's not even raining. It's obviously meant to be caused by the evil surrounding the place. The idea is there is constant lightning right on top of them.

lionhead

There's a scene in Judge Dredd where every few seconds, there is a flash of lightning instantly accompanied by the sound of thunder. It happens frequently in Sleepy Hollow as well.

Phaneron

I know the scenes you are referring to. In both those instances you have no idea about the distance of this lightning. It could be (and probably is) right on top of them. You can hear that from the typical high sharpness of the sound, only heard when the flash is very close. Thunderclouds are never very high in the air so even the rumbling within the cloud itself can be heard, sometimes you don't even see lightning when it rumbles (yet there is). It's a bit far fetched but you could hear a rumbling or the thunder from a previous flash and mistake it for the flash you see at the same time. Can happen when there are continuous flashes.

lionhead

Factual error: Knocking someone out by hitting them in the head is in no way a "safe" means to incapacitate them. Leaving a person unconscious after a head injury is extremely dangerous and can lead to death. It is absurd for a hero who doesn't want to kill anyone to go around punching people out and just walking away.

BaconIsMyBFF

Factual error: In movie plots that take place hundreds or even thousands of years ago, the characters have perfectly white, straight teeth. It is a known fact that Queen Elizabeth I was virtually toothless by age 40. Good dental hygiene didn't really exist until after WWII. Some movies get it right, but only for the bad guys.

Suggested correction: False teeth have been around for centuries; they could be made from a variety of materials including wood, porcelain, or even human teeth taken from corpses or people who willingly sold their teeth to make some quick cash. People with the means to do so could acquire them quite easily, and they were often indistinguishable from a person's own natural teeth.

zendaddy621

Your reasoning is very weak. Yes, false teeth have been around for centuries, but even today with much better technology, with close observation you can tell someone has false teeth. Everyone knew G. Washington had false teeth. No, these characters from 500 years ago are not ALL wearing false teeth.

odelphi

Australian Aboriginals have (had, before colonization) almost perfectly white, straight teeth and it's known that this is somehow related with their foraging diet. If it's true, then most people back ago could have almost perfect teeth too.

Furthermore, widespread tooth decay before great age was only a rich person's problem until refined sugar became cheap, so the peasants wouldn't have bad teeth either.

dizzyd

Tooth decay is not caused by refined sugars. Any carbohydrates will promote bacterial growth, which can cause tooth decay. Additionally acidic food and drinks and alcohol (which can be high in carbohydrates) can damage the teeth and promote bacterial growth. And the mistake is talking about movies in general with countless characters, not a few select characters with significant means.

Bishop73

Thanks for your response. You said it better than I could have.

odelphi

I mostly agree with you, but I am talking about characters who are rich with perfectly white teeth (and more importantly) great gums - no recession. What I disagree is that only sugar causes teeth decay. Not true. Virtually all food breaks down into simple sugars with enzymes in your saliva.

odelphi

Factual error: The hugely exaggerated amount of flame and damage produced by military weapons such as a hand grenade. They make a loud boom, a bit of a flash and a small stain of black smoke. No mammoth explosion, that's for sure.

stiiggy

Other mistake: Drivers are able to look directly at front or back seat passengers for relatively long periods of time (i.e, take their eyes off the road) but don't crash or veer off the road.
