Common movie and TV mistakes

Audio problem: Non-metal items making audible metallic sounds. The audible metallic sound effect of a blade, such as a sword, when it's being drawn from a wood or leather scabbard that doesn't have a metal throat, and also when it's drawn from a fabric or leather belt.

Super Grover ★

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).

Audio problem: Guns making mechanical clicks every time they are moved, especially to show the hero is being threatened. Guns generally do have components that click e.g. the safety catch, but they have to be manipulated by the person carrying them, which is not what we see on screen.

Audio problem: Characters in a fist fight landing all punches that all sound like loud smacks or worst case (Rocky) car doors slamming.

Audio problem: When someone is holding a gun, you often hear the sound of a hammer being pulled to the rear and locked even when the gun (usually a Glock) doesn't have a hammer to pull.

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.

Phaneron ★

Audio problem: Tyres squealing on dirt roads.

Audio problem: No matter the size of the gun, or where the gun is fired, it always sounds like a huge shotgun going off in a echo-heavy canyon.
