Theatrical release: April 4, 1968.
Filmed at MGM British Studios Ltd., Borehamwood, England.
Production on the film lasted four years.
The film was based on Arthur C. Clarke's short story "The Sentinel."
2001: A SPACE ODYSSEY was added to the Library of Congress National Film Registry in 1991.
Alex North composed a score for the film, but Kubrick opted to go with more familiar classical music pieces instead.
There are four parts of the film: "The Dawn of Man," "From Earth to the Moon," "Jupiter 18 Months Later," and "Jupiter and Beyond the Infinite."
Pink Floyd's song "Echoes" was supposedly written and recorded to synchronize with the "Jupiter and Beyond the Infinite" part.
Vivian Kubrick, who plays Squirt, Dr. Floyd's daughter, is Stanley's daughter.
An early working title for the film was JOURNEY BEYOND THE STARS.
Two possibilities for the voice of HAL were actors Nigel Davenport and Martin Balsam before Douglas Rain got the part; Rain recorded his part without ever actually being on the set of the film.
Kubrick won an Oscar for Best Effects/Special Visual Effects, the only Oscar win of his career.
Bowman's spaceship is Discovery I, a name that was later used for an actual U.S. space shuttle.
A theory was perpetrated that Kubrick got the name HAL by taking the next letter preceding each one in IBM; Kubrick claimed that that was a coincidence. According to Arthur C. Clarke's writing, the name came from the technical term "heuristic algorithm."
Kubrick cut about 20 minutes from the film after the preview for critics and before the theatrical release. The original film was 160 minutes, which included an intermission, and was rated MPAA G.
Mission controller Frank Miller was an actual mission controller, and Richard Wood, who played the anchorman, was an actual BBC anchorman.
A sequel to the film, 2010: THE YEAR WE MAKE CONTACT, was released in 1984.
