Kubrick used the beginning of Strauss's Thus Spake Zarathustra in his 2001 – A Space Odyssey. In doing so he demonstrated excellent judgement, because that opening minute or so is by far the strongest part of the piece. Kubrick further confirmed his good taste by launching into the Blue Danube, by the other Strauss.
Which reminds me of the unkind quip: If Richard then Wagner, if Strauss then Johann. Forget who said that, but it must have really irked RS.
