This was actually a thread I did on FSM in 2010, but which I won’t replicate. I’d rather just post the original question once more:
I know that rejected scores is not an exclusive modern phenomenon (Herrmann’s TORN CURTAIN, North’s 2001 and so on are early examples), but was it very common in Hollywood films between, let’s say, 1930 and 1950 (just to have a specific timeframe)?
