1968 film 2001: A Space Odyssey

2001: A Space Odyssey (occasionally referred to as simply 2001) released on April 6, 1968 is a 1968 science fiction film directed by Stanley Kubrick and written by Kubrick and Arthur C. Clarke. The film deals with thematic elements of human evolution, technology, artificial intelligence, and extraterrestrial life, and is notable for its scientific realism, pioneering special effects, ambiguous and often surreal imagery, sound in place of traditional narrative techniques, and minimal use of dialogue.

The film has a memorable soundtrack — the result of the association which Kubrick made between the rotary motion of the satellites and the dancers of waltzes, which led him to use the Blue Danube waltz by Johann Strauss II, and the famous symphonic poem Also sprach Zarathustra, by Richard Strauss, to portray the philosophical evolution of Man theorized in Nietzsche's homonymous work.

Despite receiving mixed reviews upon release, 2001: A Space Odyssey is today recognized by many critics and audiences as one of the greatest films ever made; the 2002 Sight & Sound poll of critics ranked it among the top ten films of all time. It was nominated for four Academy Awards, and received one for visual effects. In 1991, it was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in The National Film Registry.
