Written and directed by Peter Hyams
Nine years after the events of Stanley Kubrick's cerebral classic, "2001: A Space Odyssey," it is now the year 2010 and Doctor Heywood Floyd (Roy Scheider, taking over for William Sylvester) has been drummed out of the space program in disgrace after the failure of the Discovery mission. The HAL 9000 computer system malfunctioned, killing four astronauts. The last survivor of Discovery, David Bowman (Keir Dullea) disappeared into a giant black alien monolith in space, leaving behind only a cryptic last transmission: "My God... it's full of stars!"
Floyd is approached by a representative of the Russian space program, who informs him that the Russians are closer to launching a mission to find Discovery than the United States. The Russians propose a joint mission - an American crew will travel aboard the Russian ship Leonov. Floyd recruits Dr. Curnhow (John Lithgow), designer of the Discovery, and Dr. Chandra (Bob Balaban), creator of HAL to journey with him to the moons of Jupiter and find the missing ship.
