Le Rouge aux Levres is a stylish, fascinating, very erotic vampire film based on Sheridan le Fanu's Camilla, the classic tale of a lesbian vampire. A young married couple, Stefan (John Karlen) and Valerie (Daniele Ouimet), honeymoon at a deserted oceanside resort where they meet Countess Elisabeth Bathory (Delphine Seyrig) and her companion Ilona (Andrea Rau).
Valerie has discovered that Stefan is a brutal sexual sadist and is drawn to the Countess because of her warmth and sensuality. Ilona attempts to seduce Stefan but is accidentally killed, and the Countess takes her revenge on his wife.
Director Harry Kumel directs with stunning visual style and maintains the erotic intensity and tension between the characters with skill, getting a particularly good performance from the magnificent Delphine Seyrig, who resembles in both mood and looks the young Marlene Dietrich.
Erotic, unusual and extremely violent, Le Rouge aux Levres, also released as Daughters of Darkness is one of the finest vampire films ever produced, making up with style and class what it might have lacked in budget.
