Byleth (Il demone dell’incesto) (1972)

“The young Duke Lionello Shandwell (Mark Damon) morbidly loves his sister Barbara (Claudia Gravy), and when he learns Barbara is married Giordano, a middle-age man, his jealousy becomes explosive, trying to separate the consorts in every way. In the meantime some mysterious crimes are followed (victims are all women, killed with a three-points blade), so the whole village is stunned. Blood’s ceremonies, insane love and incestuous relationships are the dominant elements in this film. As for its artistic value, Byleth still manages to surprise, since it represents the first genre film convinced from a perfectly pure movie-buff-like point of view, besides the incestuous thematic had not been documented on this way in an Italian horror movie.”
Euro trash gem with a very stylish mise-en-scene by Leopoldo Savona, who brings some good giallo vibe to the table and with a cool cast on his hands: Mark Damon, Claudia Gravy, Aldo Bufi Landi, Franco Jamonte. A mythical incestous story with beautiful babes, some bloody scenes with sexy nudity, gorgeous cinematography, locations and framing work, a gloved serial killer with a 3 point blade weapon (!), and above average acting in this -not very fast paced- artsy horror-sex italian effort with all that beautiful flair that only these 70s euro gems had. Have a peep.
