I have noticed a device used in a lot of horror or otherwise frightening movies and I was wondering if it has a name.
An example would be Jurassic Park III. A boy and his dad are parachute-sailing and end up getting untied from the boat and land on the island. Then in the next scene you see what you think is a huge dinosaur until you realize it is just a close-up of a toy dinosaur that a little little kid in the USA is playing with.
Or, in The Boys from Brazil, one of the litle Hitlers pushes a Punch puppet out at his mother in a way that momentarily startles the audience.
Or perhaps in a horror movie about aliens you see a horrible face pop up that scares you until you realize it is a close-up of a kid playing with a Halloween mask.
Does this device have a name?
