The 2001 screenplay was written by Clarke and Stanley Kubrick jointly, based on the seed idea in "The Sentinel" that an alien civilization left an object on the Moon to alert them to humankind's attainment of space travel. In addition, the 1953 short story "Encounter in the Dawn" contains elements of the first section of the film, in which the ancestors of humans are apparently given an evolutionary nudge by extraterrestrials. The opening part of another Clarke story, "Transience", has plot elements set in about the same time in human history, but is otherwise unrelated.

The 1972 book The Lost Worlds of 2001 contains material that did not make it into the book or film.

Clarke's first attempt to write the sequel to 2001 was a film screenplay, though he ultimately wrote a novel instead that was published in 1982. Clarke was not directly involved in the production of the second film, although he did communicate with writer/director Peter Hyams a great deal during the production via the then-pioneering medium of e-mail (as published in the book The Odyssey File) and also made a non-speaking cameo appearance in the film. Kubrick had no involvement in the 2010 novel or film, or any of the later projects.

The Space Odyssey series combines several science-fiction narrative conventions with a metaphysical tone. Since the stories and settings in the books and films all diverge, Clarke suggested that the continuity of the series represents happenings in a set of parallel universes. One notable example is that in the 2001 novel, the voyage was to the planet Saturn. 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 second book, 2010, retcons the storyline of the first book to make the destination Jupiter as seen in the film.

Clarke stated that the Time Odyssey novels are an "orthoquel" (a neologism coined by Clarke for this purpose, combining the word sequel with ortho-, the Greek prefix meaning "straight" or "perpendicular", and alluding to the fact that time is orthogonal to space in relativity theory) to the Space Odyssey series.[4]

• HAL 9000 is a sentient computer (or artificial intelligence) that becomes the primary antagonist of 2001: A Space Odyssey. HAL is also in the sequel novels and the film sequel 2010. In both films he is voiced by actor Douglas Rain.
• Dr. David "Dave" Bowman serves as the protagonist of 2001: A Space Odyssey. The character later appears in the sequel story released first as a book, 2010: Odyssey Two, and then as a movie, 2010: The Year We Make Contact, albeit as a non-corporeal entity, and also returns in two more books by Arthur C. Clarke, 2061: Odyssey Three and 3001: The Final Odyssey. In the forewords to both 2010 and 2061, Clarke makes it clear that the plots of the movies and books do not necessarily follow a linear arc, and should be seen as taking place in parallel universes, or as being variations of a main theme; consequently there are apparent inconsistencies in the character of David Bowman throughout the series. In the two movies, Bowman is played by Keir Dullea.
• Dr. Heywood R. Floyd first appears in 2001: A Space Odyssey as being in charge of the mission to investigate the alien Monolith found on the Moon. After the events that took place in 2001: A Space Odyssey, he is the protagonist of 2010: Odyssey Two and 2061: Odyssey Three. Floyd was born in 1958 in America, and by 1999 is chairman of the National Council of Astronautics, overseeing all American spaceflight operations. He has two daughters (only one in the movies, born 1994) and was widowed when his wife Marion died in a plane crash. In 2010: The Year We Make Contact, Floyd has a new wife and a five-year-old son named Christopher. Floyd was played by William Sylvester in the film version of 2001: A Space Odyssey and by Roy Scheider in 2010: The Year We Make Contact.[5]
• Dr. Frank Poole is an astronaut aboard Discovery One on the first crewed mission to Jupiter in 2001: A Space Odyssey (Saturn in the novel). He and Dave Bowman are the only crew members who were not put on board in suspended animation (hibernation). His boyhood hometown was Flagstaff, Arizona, where he visited the Lowell Observatory at its museums on many occasions. These visits sparked his interest in astronomy and astronautics, and hence he went to college to study these subjects.[6] He is the main character of 3001: The Final Odyssey. In Stanley Kubrick's 2001: A Space Odyssey, Poole was portrayed by Gary Lockwood. Tom Hanks once expressed interest in directing a film version of 3001, in which he would have played Poole, but this never came to fruition.
• Walter Curnow appears in the book and movie versions of 2010: Odyssey Two as the American engineer who designs Discovery and helps to build Discovery II to go back to Jupiter. When the joint Soviet-American mission on the Leonov is planned instead, Curnow is one of the three American experts to go on the trip, along with Heywood Floyd and Dr. Chandra. Curnow is one of the first people to set foot on Discovery again, along with Maxim Brailovsky. Due to his engineering expertise, Discovery becomes operational again. In the 1984 film adaptation, 2010: The Year We Make Contact, Curnow is played by John Lithgow.
• Dr. Sivasubramanian Chandrasegaram Pillai (often abbreviated to Dr. Chandra) is mentioned in the novel of 2001: A Space Odyssey as a scientist who instructed the computer HAL 9000 in its basic functions (in the movie, it was a "Mr. Langley"). He is a main character in 2010: Odyssey Two where it was established that he was in fact the creator of HAL, and he is a member of the joint Russian-American expedition to Jupiter on board the Soviet spacecraft Alexei Leonov. Although the character does not make any further appearances in the Space Odyssey novels, he is briefly mentioned by an elderly Heywood Floyd in the novel 2061: Odyssey Three. In the movie version of 2010, Chandra was played by Bob Balaban and is referred to as Dr. R. Chandra.
