2001: A Space Odyssey


Some spoilers to follow...

In the third act of Stanley Kubrick's 2001: A Space Odyssey, astronauts Frank Poole (Gary Lockwood) and Dave Bowman (Keir Dullea) are on a mysterious mission to Jupiter. Their only companions are three other men in cryogenic stasis and the HAL 9000, the all-knowing, all-seeing computer nicknamed Hal (voiced by Douglas Rain). Hal, who is supposedly "incapable of error," really is like another crew member; he talks to Dave and Frank, plays chess, and even expresses some trepidation about their mission to Dave. No one knows if the computer truly has feelings or motivations of its own, but as the mission progresses, Dave and Frank begin to suspect something is going wrong with their comrade. When Hal alerts them to a problem with the ship that they can't find, Hal blames human error, but this makes Frank and Dave even more suspicious. Is Hal making errors, or is Hal developing a mind -- and a mission -- of its own?
