The Devil's Mistress is a 1965 American Western horror film written and directed by Orville Wanzer. The film's plot follows Liah, an Indian half-caste, who takes her revenge on four ruthless cowboy desperadoes who have gunned down her husband for the sheer joy of killing.
Filming took place in Las Cruces, New Mexico in several weekends.
A review from Movies and Mania reads: "The Devil's Mistress is not a coherent picture; that may have been the point. Questions are posed but never answered. The couple has travelled from Salem, "to escape religious persecution" â is the woman, Liah, a witch? Why does the meat they serve their ravenous houseguests taste strange? Is Liah avenging herself by causing the deaths of these men â two of whom she kisses passionately, imparting some kind of fatal malady; another is bitten by a rattler; the fourth dies by hanging â or is she the agent of a higher power: "I will send the poison of the serpent and the mouth of the beast upon them"? The ending is characteristically enigmatic."
Rob Freese of Videoscope noted its "weird fever dream ambiance" and called the film "a decent 'bottom of the bill' feature".
