Some genius has posted a whole set of images shot from behind the scenes during the making of Kubrick’s 2001: A Space Odyssey. God bless you Sir. Or Madam. I remember seeing the film in 1969 as a young boy with my Dad at a cinema in the suburbs of Dublin. It made a lasting impression: one of bafflement and a sense of awe. Still does. Great shots. Worth a visit.
