a couple of oldies but a couple of goodies! mario bavas' 1960 classic 'black sunday' and his 1958 classic 'black sabbath.'
BLACK SABBATH was my scariest movie when i was around 11. a bunch of us girls were at a "slumber party" and this movie came on and scared the shit out of us. specifically, the one with the old lady and her ring and the drop of water. (it's a trilogy) we were screaming and scaring each other silly the rest of the night. good times. SUSPIRIA is also another old occult classic worth a looksee.
