"Daughters of Darkness" (originally titled "La rouge aux lèvres") is a 1971 Belgian-French-West German production directed by Harry Kümel that stars Delphine Seyrig as the Countess Elizabeth (Erzsebet) Bathory (a real historical figure who murdered hundreds of young women in her quest for immortality). In the film, Bathory and her young female companion (Andrea Rau) cross pathes with a young couple, Valerie and Stefan (played by Danielle Ouimet and John Karlen - Willie Loomis from TV's "Dark Shadows") who are honeymooning during the off-season in Europe. At first the couple seem fairly normal, but things quickly sour, as the woman is shown to be emotionally unstable and the man is very violent and turned on by death. Their relationship is also undermined by homosexuality on both sides. There are intimations that Stefan is in thrall to an older man back in England, and Valerie - of course - soon falls under the spell of the ageless and beautiful Countess Bathory. This mesmerizing and hypnotic film makes brilliant use of sound, mood, and color to paint an understatedly savage tableau, and it has a well-deserved cult following. It's probably too slow-moving for the average horror movie fan, however. "Daughters of Darkness" is very self-consciously an "art" film. The carefully constructed images, the nonsensical dialogue, the use of vivid reds and blues, and the extremely deliberate pacing all serve to create a film that - despite a few shockingly strange death scenes - is much closer in spirit to "Last Year at Marienbad" than it is to "The Lost Boys."
