Even if somehow you've never heard of him, you've heard him—he wrote classic scores for such films as Citizen Kane, Vertigo, North By Northwest, Psycho and Taxi Driver, among many others.
Somehow the only one he won an Oscar for was The Devil and Daniel Webster in 1942. Go figure.
Did you know he had to talk Alfred Hitchcock into using the famous strings score during the shower scene in Psycho? Hitch thought silence would play better. Which only goes to show that Hitchcock didn't know everything.
Trying to pick my favorite Bernard Herrmann score is futile, so instead, here's one you don't hear as much about, but which is every bit as important to the product on the screen as anything else he ever wrote, The Day The Earth Stood Still.
