The Smithsonian National Air and Space Museum received last year a an amazing, one-of-a-kind donation: The Arthur C. Clarke collection of papers from Colombo, Sri Lanka, the writers’ home for most of his adult life. Among the 27 linear feet of correspondence, the archivists found a letter from Stanley Kubrick about the ‘Dawn of Man’ sequence in 2001: A Space Odyssey. This was written in April 11, 1966 when the principal photography for the part of the movie set in space was well under way and the 'Dawn’ section was still in its planning stages; Clarke had meanwhile flown from Ceylon to Lawrence, Kansas, for the centennial celebrations of the local University, and was by then back in NY. The letter confirms that it was Kubrick’s idea that the lesson from the monolith (by then still in its first incarnation as the 'Cube’) was better not to be shown explicitly, but rather suggested by the spellbound reaction of the man-apes.
