Born to Be Bad is a 1950 American film noir melodrama directed by Nicholas Ray and starring Joan Fontaine, Robert Ryan and Zachary Scott. It features Fontaine as a manipulative young woman who will stop at nothing to get what she wants. It is based on the bestselling novel All Kneeling by Anne Parrish (1928).

Nicholas Ray was an American film director, screenwriter, and actor. Described by the Harvard Film Archive as "Hollywood's last romantic" and "one of postwar American cinema’s supremely gifted and ultimately tragic filmmakers," Ray was considered an iconoclastic auteur director who often clashed with the Hollywood studio system of the time, but would prove highly influential to future generations of filmmakers.
