Do you like a particular film score that many people don't know about it? This could be because the film isn't that good, it is rarely aired on TV, the score was never released commercially or maybe because the film is pretty much forgotten.
I've always loved Christopher's Gordon magnificent score for the TV film "Moby Dick" (1998)
Another example is Bronislau Kaper's music for "Mutiny on the Bounty" (1962)
Lastly, I would mention James Horner's music for "Once Upon a Forest" (1993)
