That reminds of Arthur C Clarke writing about the process of making 2001 with Stanley Kubrick. Clarke visited the set one day, and was absolutely blown away, but jokingly pointed out that somebody had left some fingerprints on the Monolith. Kubrick was furious and Clarke was seriously worried he was going to fire somebody on the spot. (I think that's in Lost Worlds of 2001, which is a fun read)
