Sleeper (1973)

Miles, a nebbishy clarinet player who also runs a health food store in NYC's Greenwich Village, is cryogenically frozen, and brought back - 200 years in the future, by anti-government radicals in order to assist them in their attempt to overthrow the oppressive government. When he goes off on his own, he begins to explore this brave new world, which has Orgasmatron booths to replace sex and confessional robots.—John Vogel
