If we’re to go by “Dr. Jekyll and Mr. Hyde” (1931), “The Black Cat” (1934), “The Raven” (1935), “Sunset Boulevard” (1950), “20,000 Leagues Under the Sea” (1954), “The Great Race” (1965), “Rollerball” (1975), and “The Phantom of the Opera” (1962, and not infrequently 1925), Johann Sebastian Bach’s Toccata and Fugue in D minor is the depraved anthem of cinematic psychopathy, degeneracy, and dystopia.
“The Silence of the Lambs” (1991) opts for something a bit more elegant. Here is an academic essay on Hannibal Lecter’s fondness for the “Goldberg Variations.”
