Charles, if you're talking about getting the scores and not the movies themselves, I have a fair number of CDs of soundtrack music which is to some extent of a "classical" nature(maybe the best classical music composed in the last 50 years or so). I'd second Alan's suggestion of the scores of Max Steiner and Erich Korngold, but at this point I'll recommend some of Bernard Herrmann's work. Two fine CDs at the top of the list are his weird/beautiful music for
The Day The Earth Stood Still and a collection of excerpts from several scores played by the
LA Philharmonic .
