The second book, 2010, alters the storyline of the first book to make the destination Jupiter as seen in the film. During production of the film, it was decided that the special effects for Saturn’s rings would be too expensive, so the voyage in the film is to Jupiter instead. The 2001: A Space Odyssey screenplay was written by Clarke and filmmaker Stanley Kubrick jointly, based on the seed idea in Clarke’s story “The Sentinel,” where an alien civilization has left an object on the Moon to alert them (the aliens) to mankind’s attainment of space travel.Clarke wrote the book in parallel with the screenplay, and there’s a distinct difference: in the novel, the voyage was to the planet Saturn.
