In comedies, a character explains confidently how good they are at something, or how they normally approach the situation, right before we see the opposite being true.
This most often involves a cop who takes his job too seriously and his wife who feels neglected. In fact, it's true for like 99% of cops in movies and shows.
When a veteran action team reassembles, there is one member who at first refuses to rejoin due to bad blood or preferring their new life.
Nuns . think about it , start thinking about all the films that feature nuns , it goes on and on , movies are crazy about them , nice nuns, evil nuns, sexy nuns,crazy nuns, singing nuns.
The protagonist starts from being a nobody. Then they get famous, and they get a bit cocky, but they'll ultimately realize that there are more important things in life than fame and glory and money, and they end up choosing their childhood friends instead, at the end of the movie. Their friends really love them for what they are, despite all the flaws.
any time a character has to climb about on the outside of a building a pigeon will suddenly fly out from behind a column to startle them and us.
Two characters are talking on the phone. One of the characters tells the other to look behind them, and the first character surprises the other by being there.
During a big fight in which the team is in trouble there is a moment in which some unexpected resource/power is finally unlocked and everyone stands there for few seconds without doing anything, then the leader screams "now!!!!" or "gooo!!" or "attack!!!" and they all get hyped, the epic music starts and the big comeback begins.
Two characters who have been estranged talk things out behind a transparent barrier (window, glass door, etc). We see them hug if they are friends or relatives (or kiss if they're romantically involved), meaning that they have fully reconciled.
Character who has been struggling with a particular skill is suddenly able to perform it during a pivotal moment, usually during the climax of a movie or episode.
Undercover cops or secret service guys talking into their lapels, and it looks so shifty. Why are they still doing that? I mean everyone has a mobile phone now.
Monster movies - a character is fleeing from a monster , they run out of road/ cornered , no way out , the monster bears down on them... leaps! And suddenly from nowhere another bigger monster intercepts them.
Usually on doctor or cop shows, a "new broom" comes in to run the hospital/department/station. They have a lot of controversial ideas which senior management like, but the folks on the front lines hate. But they push their agenda further and further and piss off so many people that eventually they are forced out. At this point, probably a main character who is well liked amongst their colleagues is put in charge and everyone is happy.
In slashers or murder mysteries, a camera shot will trick the audience into thinking somebody is the killer who isn’t, usually portraying them with dark, intimidating lighting or wearing a similar costume to the villain, before we see that the situation is totally different. Often, the villain’s theme will accompany the red herring camera angle.
After a character thinks they have hung up the phone on somebody, they say something insulting about the other person. The insulted person is still on the line and lets the first person know.
Whenever someone is stabbed we hear a metal scraping against metal sound, which doesn't make any sense.
A good/innocent character is framed/accused of doing something bad/deemed guilty/seen has having bad intentions, etc...the audience knows the character is innocent/good but other characters believe the lie/rumor, etc.
Usually on sci-fi shows, there's some kind of incursion on the ship/station/base, no immediate solution is found so a self-destruct mechanism is set. The threat is dealt with and the self-destruct cancelled with seconds to go. Or for that matter in action movies/spy shows, there's a bomb that is defused just in time.
It is completely socially acceptable for people to walk into someone else's home without knocking, even to the owners of the said home.
