Origins
2001: A Space Odyssey began at a lunch in 1964 where director Stanley Kubrick told publicist Roger Caras he wanted to “make the proverbial good science-fiction movie”.
Caras put him in touch with sci-fi author Arthur C. Clarke, who immediately replied by telegram: “Frightfully interested in working with enfant terrible.”
Together, they expanded Clarke’s short story The Sentinel into a 130-page script, which evolved into both the screenplay and Clarke’s companion novel.
Kubrick was also heavily inspired by the 1960 Canadian documentary Universe, even hiring its narrator, Douglas Rain, to voice the evil AI, HAL 9000.
