American sweetheart Jill Clayburgh threw a curve ball at the height of her career in the perverse Luna (1979). She plays a recently widowed opera singer in Italy who becomes sexually involved with her 14-year-old son. He's a heroin addict, so it's not clear whether he's up for the job. But then, if Mr. Skin had a mom as hot as Jill, he'd be running up that hill to fetch more than a pail of water. The risqué film offers the hot act-chest an opportunity to flash the goods. She's changing and bends over, exposing her rumptastic seat-meat, and even flashes a bit of tit and muff. If that doesn't get her son off the junk, nothing will!
