Biller is a brilliant student of the genre, and she fills every scene with a nudge-and-wink reference to a host of forebears, including George Romero’s wicked B-movie Hungry Wives (also known as Season of the Witch), Ted V. Mikels’ creepy and garish Blood Orgy of the She Devils, and Paul Wendkos' utterly strange and beguiling shocker The Mephisto Waltz, which featured Alan Alda playing against type as a demonic classical pianist.
Their floodgates having opened for a while by the success of “Rosemary’s Baby,” such exercises were occasionally major-studio releases (“The Mephisto Waltz,” “The Pyx”), but more often grade B to Z (“Simon King of the Witches,” George Romero’s “Hungry Wives,” Ted V. Mikels’ “Blood Orgy of the She Devils”).
