Common movie and TV mistakes
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: 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.odelphi
Character mistake: In almost every film or TV show, if the villain actually bothered to kill the hero as soon as they met face to face instead of just talking about their plans, the villain would actually succeed in his or her plans. Instead, the villain letting the hero live becomes their real downfall.
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.Phaneron
Deliberate mistake: In fight scenes, it's often one person against a small army. Despite having the person greatly outnumbered, the enemies proceed to attack them one at a time, allowing each to be easily dispatched. The whole point of having so many is to overwhelm your enemy... not take turns getting punched out.Quantom X
Factual error: Someone gets punched in the face or otherwise knocked out and comes around hours later, then goes on to pick up where they left off as best as possible and forget the incident in about 30 seconds. If you've been unconscious for hours you've got a traumatic brain injury and need medical attention, you won't be hunting down your assailant any time soon.Jon Sandys
Factual error: In many films and TV series that feature passwords being cracked by a "brute-force" attack, individual characters of a password are found independently of each other. (See Ocean's Eight, Under Siege 2, various episodes of Alarm für Cobra 11 - Die Autobahnpolizei, or Person of Interest.) In reality, this is impossible; most of the times the password itself is not stored anywhere. Rather, an irreversible cryptographic hash of the password is stored, and the typed password's hash is compared with that. Either the whole thing is right or no access is granted.FleetCommand
Factual error: Snipers using a laser mounted to their rifle to line up their target. Snipers in real life don't use lasers in this manner. For one thing, it gives away their position, and additionally because lasers won't line up a target accurately at a long range, as the bullet is affected by gravity, the rotation of the Earth, and other factors.Phaneron
Factual error: People using computers and having what's shown on the monitor's screen projecting clear sharp mirrored images onto their faces. That's not how monitors work. For example in Jurassic Park, when the raptor breaks into the control room and is hopping around the computer workstations, sharp, distinct "GTAC" genetic coding is shown projected from a computer screen across the raptor's face. Another example is seen in the 1995 film Hackers, when sharp, distinct text and even graphics are shown projected from an early laptop onto the faces of Angelina Jolie and Jonny Lee Miller.
