Uh, FRANKENSTEIN and DRACULA and THE WOLF MAN are “campy horror movies” ?
Correction: FRANKENSTEIN (1931) is a classic of world cinema; THE WOLF MAN (1941) is a darn good flick; and DRACULA (1931) sucks.
Bach’s “Toccata in D Minor” (horror movies rarely make it to the “Fugue” part) does not figure in the sound track of any of these films. It IS, however, used in ROLLERBALL.
For the record, the creepy music used during the opening credits of Universal Studios’ DRACULA and THE MUMMY (1933) is from Tchaikovsky’s ballet SWAN LAKE.
