The Cinefix team are back once again with their series on movies based on books. This instalment is in two parts and is slightly different. 2001: A Space Odyssey wasn’t so much a movie based upon a book as much as it was a collaboration between Kubrick and Clarke.
I think the summary in the second video (from about 9:40 onward) encapsulates the main differences between the book and the movie nicely. Essentially Kubrick dispensed with the pedantic explanations and descriptions in favour of stunning visuals and esoteric story telling. Whereas Clarke made that esoteric story telling understandable with all the motivations and insights. I.e. to understand the film read the book, to experience the book watch the film.
