Although he was the first New Wave director to begin work on a feature film, "Paris Belongs to Us" was not released until 1961, by which time Chabrol, Truffaut and Godard released their own first features and popularised the movement worldwide. Rivette became editor of "Cahiers du Cinéma" during the early 1960s and publicly fought French censorship of his second feature film, "The Nun" (1966). He then re-evaluated his career, developing a unique cinematic style with "L'amour fou". Influenced by the political turmoil of May 68, improvisational theatre and an in-depth interview with filmmaker Jean Renoir, Rivette began working with large groups of actors on character development and allowing events to unfold on camera. This technique led to the thirteen-hour "Out 1" which, although rarely screened, is considered a Holy Grail of cinephiles. His films of the 1970s, such as "Celine and Julie Go Boating", often incorporated fantasy and were better-regarded. After attempting to make four consecutive films, however, Rivette had a nervous breakdown and his career slowed for several years.
