The Movementarians was a villainous cult that appeared in The Simpsons episode The Joy of Sect. They are first seen on the Springfield airport inviting people to spend a free weekend on their community compound, during which they convince them to resign their possessions and join the Movementarians to work in their community farm, all of this with the help of brainwashing films and songs, group therapy sessions, low-protein gruel, and the promise of taking them to the planet of Blisstonia in a spaceship which is kept inside of "The Forbidden Barn". The head of this organization is a mysterious man known as "The Leader", who is responsible for the spaceship and the mission involving it.
