Sleeper is a 1973 American science fiction comedy film parodying a dystopic future of the United States in the year 2173, directed by Woody Allen and written by Allen and Marshall Brickman. The plot involves the misadventures of the owner of a health food store who is cryogenically frozen in 1973 and defrosted 200 years later in an ineptly led police state. Contemporary politics and pop culture are satirized throughout the film, which includes tributes to the classic comedy of Buster Keaton, Harold Lloyd, and Charlie Chaplin. Many elements of notable works of science fiction are also paid tribute to, or parodied.
