Rereleased in 1981 as Holy Terror. Ebert's Dog of the Week was to the distributor for the film's deceptive advertising campaign. Brooke Shields appears in the film in a supporting role, not a lead role.
Multiple references: A Psycho poster can be seen in the background in one scene; Aunt Annie's stabbing on the staircase is designed to resemble the shower murder; and the music imitates Bernard Herrmann's score in some moments.
