President Merkin Muffley (Peter Sellars) in the film Dr. Strangelove (1964)
(Narrating) But they showed no corrections of any kind. Not one. He had simply written down music already finished in his head. Page after page of it as if he were just taking dictation. And music, finished as no music is ever finished. Displace one note and there would be diminishment. Displace one phrase and the structure would fall.
Antonio Salieri (F. Murray Abraham) in Amadeus (1984)
