Common movie and TV mistakes - page 8

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.

Other mistake: People getting into their car and adjusting their rear view mirror, despite it being their car that they were the last one to drive, so what needs changing? Of course it's normally just to give a reason for them to see something or someone behind them they otherwise would have missed.

Suggested correction: Also, you don't always sit in the exact same position when getting in the vehicle. I adjust my mirrors sometimes simply cause I slouch when I drive, then later I'll sit up straight, then later I'd lean back while driving. Each time changing my point of view through the mirrors.

Other mistake: A TV will be turned on exactly at the moment an important plot point is being explained or shown. Typically it will be a news story that a news anchor will tell from the beginning. Never is the TV turned on with a commercial playing or some other news being read.


Other mistake: Someone coming into a room, or situation, and delivering a line in response to what was just said, even though there was no way they were able to hear what was just said (or even knowing what the conversation was about).


Deliberate mistake: Someone drives a car they've never driven before and they drive off without adjusting the driver's seat or mirror.

Revealing mistake: Pizza that is supposed to be hot and fresh because it was just delivered but is obviously cold and stale. There is never any melted cheese, the slices are perfectly cut and come apart easily, and the slices are firm instead of drooping. Nobody would ever pay for a pizza if it was delivered looking that way.


Factual error: People running away from explosions and just barely escaping the fireball. Never mind the fact that would be pushing a wave of superheated air in front of it which would kill them just as easily as the bit you can see.

Revealing mistake: In many in-car scenes, the background shown outside the windows either doesn't change or is the same scene used over and over.

Suggested correction: I don't think I've ever seen this outside of animation. It certainly isn't a common error. Can you cite some specific examples?

What is more common in driving scenes, especially in crowded cities, is drivers never having to stop for street lights or make turns. They continue driving through the city in a straight line as the characters talk.

Factual error: Vehicles used in films and programmes set in past decades that have age related number plates, classic car enthusiasts spot these straight away.

Revealing mistake: Whenever people drive in cars at night, lights angled upward are used so the characters' faces can be seen.

Factual error: A character in hospital removes various medical monitors from their body (or someone else's) but alarms don't sound on the equipment in the room.

Deliberate mistake: When someone gets into a car and drives away the doors are unlocked with the keys already in the ignition.

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.

Revealing mistake: After somebody gets run through with a sword, knife, spear, etc., and withdrawn from the stabbed body, there is no blood, gore, etc., seen on the blade.


Factual error: Whenever there's an officer involved shooting in television or movies, the officer in question always goes about their work as though nothing has happened. In real life, this is a big deal. It's blasted all over the news and the officer is always placed on administrative leave pending an investigation to make sure the shooting was justified.

Character mistake: When someone tries to call another person's cell phone in an emergency situation and it goes to voicemail, but they just keep calling over and over (with or without leaving a message). They never try sending a text message or similar, they just repeat the same pattern despite knowing the other person isn't answering.


Factual error: Characters who have lost an enormous amount of blood who are not only still alive near the end, but sometimes they don't even display signs of shock from blood loss. In reality, these characters would have died very fast.

Factual error: In recent years, blood tends to be represented with a certain degree of realism, but in past eras especially before the 80s, the industry standard for fake blood appeared to be a much brighter red that often looks odd to a contemporary eye, and distinctly fake. In general, every movie sorta has its own 'blood' not necessarily factually accurate.

Factual error: In numerous sci-fi films and TV series, planets, moons, and other similar celestial objects always appear to have gravity equal to that of Earth regardless of the object's size or mass. For example, a moon the same size as a small planet (such as Yavin 4 or Endor's forest moon from the Star Wars films) has the same apparent gravity as larger bodies, while in reality, the smaller objects would have noticeably less gravity than larger ones.


Factual error: Police detectives working cases in which they are personally involved; such as the murder of a friend, family member, or their partner. Even though their superiors will often warn them to stay away from the investigation, the cops will continue to work the case on their own. Oftentimes films will imply that the cop should leave the investigation alone "for his own good", but in reality a cop investigating a case they are part of would seriously taint any evidence they uncover. If taken to trial, a defense attorney could easily have that evidence thrown out. Writers tend to get around this by having the villain engage in more crimes and be caught "red handed" or by simply having the villain be killed by the end. However it is still borderline insanity to see a cop investigating his wife's murder.
