Revealing mistake: So many times people drinking coffee and similar from cups, they're empty. These cups are being tilted so much if they had any liquid in them it would be spilled everywhere. Or else the sound of the empty cup being put down is that of an empty cup, or else the cups are defying the laws of gravity which should be applying to full containers.
Common movie and TV mistakes - page 3
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: Actors playing police, soldiers or agents who keep their fingers on the triggers of their firearms. In real life, trigger discipline is an early and repeated part of firearms training. This is often most obvious on movie posters. This mistake has become less common as military veterans started to become advisers to movie makers and actors have sometimes undergone training before filming begins.

Suggested correction: Except in the case of Secret Service Agents on the Presidential detail who are trained to keep their finger inside the trigger guard any time they draw their weapons.
Not a counter-correction, but has this been seen in fictional shows about the Secret Service? Eg In The Line of Fire or Olympus Down. It could be an interesting mistake or trivia, depending on the era and accuracy of the show.
Yes, it was a plot point in Line of Fire, but I have no idea if the finger inside the trigger guard policy was made up or true. Your suggestion that this is an interesting mistake is a good one. I doubt the Secret Service will be giving us any confirmation on how they train their agents.
Factual error: In many action movies someone will instantly kill a man by approaching them from behind, grabbing their cheek, and twisting their head to the side, breaking their neck. The move is even frequently used one-handed. The torque required to actually break a neck this way is enormous and would require much more leverage than simply standing behind someone and twisting their head. Neck cranks are certainly real but they are done in a more traditional "head-lock" style on a grounded opponent. Also, a broken neck is not always fatal, let alone instantly fatal. A broken neck is not even an assured knock-out, so it is absurd to use this move as an effective "stealth kill" in spy movies.
Deliberate mistake: Night vision goggles are often depicted as having glowing lenses and sometimes with interesting lights on them. This is designed to make the goggles look cool and technically advanced for the audience. In real life, external lights would stop the goggles from working, dazzle the wearer's team mates, and be visible to any enemy.
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.
Audio problem: Characters holding conversations on board aircraft in flight where they wouldn't normally be audible, such as military helicopters or cargo planes. In real life, those are loud places where people wear hearing protection and communicate with radios or built-in comms. (Not a mistake for luxury helicopters or airliner-sized cargo planes with soundproofing).
Factual error: Characters gain access to secure facilities using a single thing: a stolen ID card, fingerprint on sticky tape etc, but with no second factor to verify identity like a PIN code. This might be appropriate for something low key like the back room of a store but in thrilling shows the characters are usually trying to get into places like the CIA or high tech laboratories. In real life, higher level security access controls include at least two factors to reduce the risk of unauthorized entry. This is often a deliberate mistake by movie makers as it would slow the story down to describe multiple security measures and show how the characters gain everything needed for access. Exceptions are movies like Mission Impossible or Sneakers where this sort of complexity is part of the plot.
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.
Factual error: In many TV shows and movies that show two parties speaking to each other on either a landline phone or pay phone, as soon as one party hangs up the phone, the other party hears an instant dial tone. Phones did not have a dial tones after calls were disconnected in reality, but rather silence followed by loud annoying buzz sounds.
Factual error: Often when bombs are shown falling, they're depicted with a distinct whistling sound. Two problems there. Bombs don't inherently whistle - some bombs in WW2 were specifically fitted with whistles for the psychological warfare element, but the vast majority are silent. Secondly, the standard noise heard from the ground, a high pitched whistle slowly getting lower, is wrong. The doppler effect, whereby a sound changes as it moves closer to someone hearing it, means the pitch heard would increase, not decrease, as a bomb falls towards you. The sound most often used in movies/TV shows of a whistling bomb is what the pilots dropping the bomb would hear, not the people it was falling towards.
Other mistake: Despite having killed two dozen people, the hero will always be allowed to walk away at the end without any police officer so much as taking a statement.
Factual error: When characters are knocked out with syringes or cloths, they almost immediately go under when actually it would take a few minutes, not seconds. Not to mention the likelihood of getting the dosage wrong and killing them, not knocking them out.
Factual error: Impacts from firearms don't throw people back when they get shot.
Factual error: When pistols are empty, the person holding it is often surprised when it clicks empty. In reality, the slide on semi-automatic pistols lock back when the gun runs empty, making it easy to see that you're out of ammo. Sometimes happens in movies, often doesn't.
Factual error: If a super speed character like Superman or Quicksilver grabbed and/or suddenly stopped people, such actions would most certainly kill the people they are trying to save. Taking them zero to hundreds of miles an hour or vice versa in a split second would snap necks, break bones, slosh brains, and pull apart limbs.
Factual error: Characters, typically the hero, can crash through windows without so much as getting a cut on them.

Suggested correction: Depending on the age of the window, that's the whole point. Safety glass is designed to break in a way to stop people getting hurt.
Not every window is made from safety glass. When was the last time you saw a movie where a main character crashed through a store window, office building window, house window, plate glass window, etc. and ended up getting shredded to ribbons?
You don't often see blood but items of clothing do get ripped. One example I can think of off the top of my head is The Last Stand where Arnie gets chucked through a glass door. His jacket gets rips on it.
For whatever it's worth, the one time in my life I had to break through a window in an emergency situation, it was definitely not safety glass and I got some fairly deep cuts even though I thought I'd cleared away the pieces. Also in spite of everything I made sure to smash it with an object because I knew there was no way I was just going to be able to leap through a solid pane of glass, and I suspect even if I did I'd just end up impaling myself on a huge shard.
Factual error: In almost every sci-fi feature, things like explosions, laser blasts, ships colliding, asteroids hitting, and planets exploding, can all be heard. However in reality sound can not travel though empty space. So almost all of that would really be completely silent.
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: Whenever someone needs to dump out someone's garbage because they're looking for something, it's always dry and clean, never disgusting.
Deliberate mistake: The criminal tells his evil plans to a priest, who is then unable to prevent a crime because of the "seal of the confessional." Yes, priests may not tell another what is heard in confession, however the 'seal' protects only those who seek absolution for past sins. Confessionals are not boxes into which you can tell a priest your dastardly plans and they can't do anything about it. There is no seal on this misuse of the confessional. Examples include 'Priest' (1994).
