Guru, the Mad Monk is a 1970 horror film that introduces viewers to a deranged monk (Neil Flanagan), who has as many personalities as he has fiendish plots and elaborate costumes. Guru operates a prison colony church on the peaceful, seldom-visited island of Mortavia with the assistance of his one-eyed hunchback servant, Igor (Jack Spencer). To supplement his meager cleric's income, Guru runs a profitable side business selling bodies of prisoners to the nearby medical school. When the warden's beloved Nadja (Judith Israel) herself is incarcerated, Guru valiantly saves her from a date with the executioner, but the warden is now indebted to the bloodthirsty monk. Pressed into service, the warden must join Guru, his vampire mistress Olga (Jacqueline Webb) and Igor in a maniacal odyssey of amputation, decapitation, grave robbing and blood drinking. The film was written and directed by Andy Milligan, who also constructed the sets and fabricated the costumes.
