An ageing, alcoholic Hollywood star employs a young man to assist with the staff at her Hollywood mansion but he turns out be a drug addicted, scheming, woman killing maniac. Miriam Hopkins plays the star perfectly, and this was to be her final role; David Garfield convincingly plays the handsome psychopath. As others have said this is "Sunset Boulevard"/"Baby Jane" but with lots of gore plus psychedelic drug sequences. It really is something of a curiosity, trashy but fun. I can find very little written about this in my various movie books, sad because it is a film that deserves to be better known. I have the original British VHS released by the notorious label Vipco, they were not shy in pushing this as a gory slasher movie and I guess for 1970 it was explicit. It is available on DVD under the title Hollywood House of Horror.
