Movie cliches

Someone is seemingly recognised (usually a villain). The main character grabs him and turns him around only to discover its someone else.

Sometimes in action movies appears, from nowhere and as surprise effect, an helicopter without anyone having heard it.

When you have a family that live in the same household and grew up in the same area yet they all have different accents. Same with a group of people who all grew up together in the same place but have different accents.

They have an affair, after making love as if there were no tomorrow the first thing she says is:" oh my God, what have I done.....this has been a mistake...."

When they put a scoop of gunpowder in each shoe and hold an egg in their mouth then ignite the shoes and wasps come out instead of blood.

Trying to appeal to as wide an audience as possible by including things that aren't necessary. Eg Love interests in war films *looks at Pearl Harbor*

"Pick me up tomorrow at seven?"
"Okay! It's a date!"
(They walk away/hang up their phones)

WHERE!? WHERE ARE YOU PICKING HER UP!?
