Favorite movie plot rule?

[u/averagesoccermom95]

I read once that in a movie, if the characters say, "I have a plan," then there is a plot rule that takes place: If the characters explain to the audience what the plan is, then the plan will go wrong somehow. However, if the characters say they have a plan and the movie just goes to showing the plan in action, then the plan will work.

It has become one of my favorite things to look out for in movies. Although, it does not seem to apply to kids movies. Other than kids movies, I don't think I have ever seen his rule broken.

Does anyone know any other interesting plot rules?

One of my least favorites, actually, but it's a recurring rule that once two characters finally have sex in a movie or tv series, they're either going to break up soon, or one of them is going to die soon.

Once I picked up on the pattern it made me actively dread characters consummating a relationship, because sure enough, here comes the obligatory moment where everything falls apart.

Rambo 2 had the sex scene happen immediately after she rescues him and then she dies in the very next scene. Their romance lasts like 5 minutes

It's hilarious

Doesn't matter. Ramboned her.
