HAL 9000

HAL's iconic camera eye - HAL 9000 is the sentient on-board computer of the Discovery One spacecraft in Arthur C. Clarke's fictional Space Odyssey saga. HAL (Heuristically programmed ALgorithmic computer) is an artificial intelligence which interacts with the crew, usually represented only as a red television camera "eye" that can be seen throughout Discovery. He speaks in a soft voice and a conversational manner, in contrast to the ship's crew who speak in a terse way, with little inflection. The voice of HAL 9000 was portrayed by Canadian actor Douglas Rain. HAL became operational on 12 January 1997 (1992 in the film) at the HAL Laboratories in Urbana, Illinois as production number 3. His first instructor was Dr. Chandra (Mr. Langley in the first film). HAL is capable not only of speech, speech recognition, facial recognition, and natural language processing, but also lip reading, art appreciation, interpreting and expressing emotions, reasoning, and playing chess, in addition to maintaining all systems on an interplanetary mission. HAL was ranked No. 13 on a list of greatest film villains of all time on the AFI's 100 Years. 100 Heroes and Villains. In the French-language version of 2001: A Space Odyssey, HAL's name is given as "CARL", for Cerveau Analytique de Recherche et de Liaison ("Analytic Brain for Research and Communication"). The camera plates, however, still read "HAL 9000". In 2001: A Space Odyssey, HAL begins to malfunction in subtle ways, and as a result, the decision is made to shut HAL down in order to prevent more serious malfunctions. The sequence of events and manner in which HAL is shut down differs between the novel and film versions of the story. He is the film's main Antagonist. In the film, astronauts David Bowman and Frank Poole consider disconnecting HAL's cognitive circuits when he appears to be mistaken in reporting the presence of a fault in the spacecraft's communications antenna. They attempt to conceal what they are saying, but are unaware that HAL is capable of lip reading. Faced with the prospect of disconnection, HAL decides to kill the astronauts in order to protect and continue its programmed directives. HAL proceeds to kill Poole while he is repairing the ship. When Bowman goes to rescue Poole, he is locked out of the ship, and HAL proceeds to disconnect the life support systems of the other hibernating crew members, killing them in their sleep. Dave manages to force his way back onto the ship by jumping through space and prying open an emergency airlock, outside of HAL's control. In the novel, the orders to disconnect HAL come from Dave and Frank's superiors on Earth. After Frank is killed while attempting to repair the communications antenna, Dave begins to revive his hibernating crewmates, but is foiled when HAL vents the ship's atmosphere into the vacuum of space, killing the awakening crew members and almost killing Dave. Dave is only narrowly saved when he finds his way to a spacesuit which has its own oxygen supply. In both versions, Bowman then proceeds to shut down the machine. In the film, HAL's central core is depicted as a crawlspace full of brightly lit computer modules mounted in arrays from which they can be inserted or removed. Bowman shuts down HAL by removing modules from service one by one; as he does so, HAL's consciousness degrades. HAL regurgitates material that was programmed into him early in his memory, including announcing the date he became operational as 12 January 1992. When HAL's logic is completely gone, he begins singing the song "Daisy Bell" (this being a reference to the first song played on a computer, the UNIVAC I, was "Daisy Bell"). HAL's final act of any significance is to prematurely play a prerecorded message from Mission Control which reveals the true reasons for the mission to Jupiter, which had been kept secret from the crew and not been intended to be played until the ship entered Jovian orbit.
