Inspired by Arthur C. Clarke's short story "The Sentinel," director Stanley Kubrick's senses-shattering tale of life and "afterlife" in outer space revolutionized science-fiction movies. The film depicts the discovery of a large black monolith at the dawn of man, an identical obelisk found on the moon, and two astronauts terrorized by their ship's computer, HAL 9000. With Keir Dullea, Gary Lockwood, William Sylvester, and Douglas Rain as the voice of HAL. 148 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital 5.1, French Dolby Digital 5.1; Subtitles: English, French, Portuguese, Spanish; theatrical trailer.
