One of the more unusual sex/horror efforts of the 60s, Mantis in Lace concerns a young dancer named Lila (Susan Stewart) who seduces men and murders them in a grimy warehouse while tripping on LSD. Bizarre hallucinations alternate with fairly bloody slasher sequences and the usual softcore grinding. Devotees of the ghoulie subgenre of vintage sleaze will appreciate Laszlo Kovacs rather inspired cinematography and some imaginative touches by director William Rotsler. What they may not appreciate is the annoying theme song (Lila). ~ Robert Firsching, All Movie Guide
