It could also be that Duning was just incredibly talented and able to work under this kind of pressure. Someone might scoff at the notion that Jerry Goldsmith composed the score for "Chinatown" in 10 days, but he did it, it's a fact. The thing is, he was more insanely talented musically than any of us here, plus this was a career he had been doing for decades. Duning was already proficient at film and TV scoring, so he was accustomed to working fast and again, was exponentially more talented musically than any of us talking about this set.
