Springfield of Tomorrow is a film about Springfield in the future from 1956.
Bart's class once saw the movie. In the movie, they saw Bill who had to take the bus, caught out in the rain, and Sam who had to take the subway where he was packed like a tuna. The movie then focused on Mel who owned a plutonium-powered auto that had got plenty of room for all of his wife's shopping. They then picked up their son Junior from Astroid Elementary by catching him by a robot arm that needed "a little adjustment". When they later wanted a little privacy, they flash-froze Junior until further notice.
