The Scream Extractor in Monsters Inc. (2001)
The setup for Monsters Inc. is a little dark to begin with: the monsters’ entire way of life is powered by the screams of the children they scare. The scares are lightened by the twist that the monsters are more scared of the kids than the kids are of the monsters.
But things get a little too high stakes when Boo is strapped into something called a Scream Extractor to optimize the amount of terrified volume she projects. Luckily Sully (John Goodman) saves her, in one of the most cathartic rescues of the Pixar movies.
