2001: A Space Odyssey

2001: A Space Odyssey is a science-fiction narrative, produced in 1968 as both a novel, written by Arthur C. Clarke, and a film, directed by Stanley Kubrick. It is a part of Clarke's Space Odyssey series. Both the novel and the film are partially based on Clarke's short story "The Sentinel", written in 1948 as an entry in a BBC short story competition, and "Encounter in the Dawn", published in 1953 in the magazine Amazing Stories.

After deciding on Clarke's 1948 short story "The Sentinel" as the starting point, and with the themes of man's relationship with the universe in mind, Clarke sold Kubrick five more of his stories to use as background materials for the film. These included "Breaking Strain", "Out of the Cradle, Endlessly Orbiting...", "Who's There?", "Into the Comet", and "Before Eden". Additionally, important elements from two more Clarke stories, "Encounter at Dawn" and (to a somewhat lesser extent) "Rescue Party", made their way into the finished project. One other element (crossing vacuum without an intact pressure suit) is from the short story "Take a Deep Breath".

Clarke was originally going to write the screenplay for the film, but this proved to be more tedious than he had anticipated. Instead, Kubrick and Clarke decided it would be best to write a prose treatment first and then adapt it for the film and novel upon its completion.

Clarke and Kubrick jointly developed the screenplay and treatment, which were loosely based on The Sentinel and incorporated elements from various other Clarke stories. Clarke wrote the novel adaptation independently. Although the film has become famous due to its groundbreaking visual effects and ambiguous, abstract nature, the film and book were intended to complement each other.

The film was written by Clarke and Kubrick and featured specialist artwork by Roy Carnon. The film is notable for its scientific realism, pioneering special effects, and provocatively ambiguous imagery and sound in place of traditional narrative techniques.
