I love Henry Mancini’s, "Theme from ‘Lifeforce,’"but it doesn’t really fit the movie.
Not a horror movie, but in the original Rollerball, with James Caan, the movie opens with a stadium gradually being prepared for a game. The music over it all is Toccatta and Fugue in D Minor.
Gotta go with “Vertigo” and “Jaws”
Hitchcock - Psycho murder scene
Psycho
Cape Fear with Gregory Peck
The Hunter with Robert Mitchum
Wait till Dark
Frankenstein
James Mason as Captain Nemo plays it on the organ aboard the Nautilus in Disney’s 1954 20,000 Leagues Under the Sea. Not to be outdone, Herbert Lom plays it on the organ aboard the Nautilus in Ray Harryhausen’s Mysterious Island, which obviously tried to imitate the style of the Disney film.
