I didn't see mention of this in my search. There's an article about lost footage found in pristine condition of lost footage from the Kubrick film. The article says it's likely footage Kubrick cut out right before release to improve the film's pace. http://www.thewrap.com/deal-central/column-post/wb-uncovers-lost-footage-kubricks-2001-space-odyssey-23309 It would be interesting to see the footage someday on blu ray. But from the description of the scenes cut out, it doesn't sound like it would add anything to the narrative.
