All fine choices. Yes, "Black Sabbath" is superb. So is "Black Sunday." (And I admit, I sort of get them confused. One is the story about the witch. One is the trilogy with the amazing vampire story at the end.)
I've always thought Barbara Steele was one the most extraordinary visions in horror films. Those eyes ...
Love the Davis films as well, though never a fan of "Lady in a Cage." (Such a mean spirited film.) Much prefer "Die, Die, My Darling."
