HAL 9000 is a fictional computer portrayed in the film 2001: A Space Odyssey (1968). The film imagines a manned mission to Jupiter in its titular year and HAL is the ship's "brain and central nervous system". Unfortunately, HAL becomes paranoid and, for fairly complicated reasons, concludes that he has to kill the crew in order to fulfill his programming. HAL's voice in the film was provided by Canadian actor Douglas Rain.
