Aaron Copland too, his score for
The Red Pony was turned into an orchestral suite and is performed by orchestras.
The mention of
Kings Row in the TCM thread reminded me of how great
Erich Wolfgang Korngold's score is for that film, really one of my favorites, and a pretty good movie, too! Korngold's best know scores are probably the ones he did for Errol Flynn swashbucklers, and while they are great for that type of film, Kings Row is something much deeper and more moving, closer to his non-film music and very different from the usual film scores around this time. And also apparently a big influence on John Williams'
Star Wars score (you can here it right off the bat).
Herrmann is probably the best though, at his best he really changes scenes with his music, to the point that he is almost a co-auteur in certain films. The snowy chase scenes in
On Dangerous Ground is one of my favorite non-famous examples of how much of an impact his music has. Also, one of the most recognizable composers, multiple times I've had films on in the background, heard a strain of the score and thought "that sounds like Herrmann" and been right,
The Snows of Kilimanjaro is one I remember that happening with. John Williams' is that way too, even if I don't love all his scores as much as some do.
The Rare Breed is an early one that makes you say "hey that sounds like..." Probably the best thing about that movie, though, which isn't saying much.
