monolith. Dr. Dimitri Moisevitch: A good friend of Floyd's (and citizen of the rival U.S.S.R.), who diplomatically presses Floyd about the Americans' "outbreak" cover story (intended to keep outsiders away from the discovery of the Tycho monolith) while both are aboard Space Station One, a stopping-point between the Earth and the Moon. In the film, Moisevitch's role is carried out by a character of a different name, Dr. Andrey Smislov, while the character of Moisevitch as-such makes appearances throughout the rest of the Odyssey series and in the opening scene of the 2010 film. Moisevitch, like Floyd, is written as a cagey and worldly bureaucrat. Ralph Halvorsen: Administrator of the Southern Province and leader of Clavius Base, Halvorsen represents American interests on the Moon, and receives Floyd at Clavius to gather information about the Tycho monolith. Whitehead, Kaminski, and Hunter: a trio of astronauts who are put aboard the Discovery in hibernation, in order to conserve resources. In the event of the deaths of Bowman or Poole, the hibernating astronauts are to be revived in the order given. Consequently, upon Poole's presumptive death, Bowman partially revived Whitehead until HAL depressurized the Discovery, killing the three while Bowman escaped to a secure area. In the film, HAL kills the trio by simply shutting off their life support functions while Bowman is on EVA in an effort to recover Poole's body; in the film, the trio are instead styled as Kimball, Kaminsky, and Hunter. Dr. Chandra: Briefly cited by HAL during his de-activation as being his first instructor, who taught him to sing "Daisy". In the film, this initial instructor is instead named as "Mr. Langley"; however the character of Dr. Chandra features throughout the rest of the Odyssey franchise, especially in the 2010 book and film. Anna, Betty, Clara: The namesakes of the Discovery's three EVA pods. In other films and novels of the franchise, these pods are given different naming conventions. Betty is the pod which, under HAL's control, presumptively causes Poole's death. Sequels 2010: Odyssey Two, a 1982 sequel to the book, was adapted as a motion picture in 1984. Clarke went on to write two more sequel novels: 2061: Odyssey Three (1987) and 3001: The Final Odyssey (1997). the last two novels have yet to be adapted as films. Reception James Blish commented that while Clarke's narrative provided essential elements of the story that Kubrick ignored or glossed
