Yes, a very interesting collection that I was pleased to revisit here. Thanks for the reminder, Preston. To counterbalance the modern bias, I would like to offer a few gems from earlier times:
"Out here [in Hollywood] everybody knows his own job -- plus music." [Attributed to Alfred Newman, though I've never seen it definitively sourced.]
"A film composer's immortality lasts from the recording stage to the dubbing room." [E. W. Korngold -- happily proved wrong in later decades.]
"You ask Mr. Hitchcock where the camera comes from and I'll tell him where the music comes from." [Attributed to Hugo Friedhofer, responding to the director's instruction (on LIFEBOAT) that music would be illogical in the middle of the ocean.]
"Film music is like a candle held beneath the screen to warm it." [Aaron Copland]
Thanks John, you're correct, of course, about the bias, and you've redressed it beautifully.
FWIW, I may be misremembering, but I think the quote attributed to Friedhofer has also been attributed to David Raksin -- by David Raksin, possibly on one of his radio programs.
