Video: 2001: A Space Odyssey Official Trailer - (1968) HD
Excerpt from Roger Ebert Reviewing 2001: space odyssey (1968), March 27, 1997, ROGEREBERT.COM
The genius is not in how much Stanley Kubrick does in "2001: A Space Odyssey," but in how little. This is the work of an artist so sublimely confident that he doesn't include a single shot simply to keep our attention. He reduces each scene to its essence, and leaves it on screen long enough for us to contemplate it, to inhabit it in our imaginations. Alone among science-fiction movies, “2001" is not concerned with thrilling us, but with inspiring our awe.
No little part of his effect comes from the music. Although Kubrick originally commissioned an original score from Alex North, he used classical recordings as a temporary track while editing the film, and they worked so well that he kept them. This was a crucial decision. North's score, which is available on a recording, is a good job of film composition, but would have been wrong for “2001" because, like all scores, it attempts to underline the action -- to give us emotional cues. The classical music chosen by Kubrick exists outside the action. It uplifts. It wants to be sublime; it brings a seriousness and transcendence to the visuals.
