Sleeper (1973)

In 1973, health food store owner Miles Munroe enters the hospital for a routine gall bladder operation. When he expires on the operating table, Miles' sister requests permission to cryogenically freeze her brother's body. After 200 years, Miles is unwrapped by a group of scientists and awakens to a Brave New World of deadening conformity, ruled with an iron fist by a never-seen Leader. Miles is forced to flee for his life when the scientists--actually a group of revolutionary activists--are overpowered by the Leader's police. He eludes the cops by pretending to be an android, and in this guise is sent to work at the home of Luna, a composer of greeting cards who thinks that the world of the future is perfect as it stands.
