As a director, Roger Vadim was known for his sensual and sometimes avant-garde films; off-screen he was known for his sensual and sometimes avant-garde lifestyle. He was married five times in all: to actresses Brigitte Bardot, Jane Fonda, Marie-Christine Barrault and Annette Stroyberg and to heiress Catherine Schneider. (He was married to Barrault when he died.) Vadim had one child each with Fonda, Stroyberg and Schneider and a fourth child with actress Catherine Deneuve. His best-known film is And God Created Woman (1956), which introduced the innocently voluptuous Bardot.
Extra credit: Vadim's 1968 film with Fonda, Barbarella, is often considered a classic of sci-fi camp... He published the personal memoir Bardot, Deneuve, Fonda in 1986.
