Des journées entières dans les arbres (in English, Entire Days in the Trees) is a 1976 French film directed by Marguerite Duras, based on her novel.

"India Song" stars Delphine Seyrig, Michael Lonsdale, Mathieu Carrière, Claude Mann, Vernon Dobtcheff and Didier Flamand.  The film centres on Anne-Marie (Seyrig), the promiscuous wife of the French ambassador in India, and was based on an unproduced play written by Duras (which itself was based on her published novel "Le Vice-Consul").  Although set in India, the film was shot mostly on location in a mansion in Paris. Arthur Rosson (24 August 1886 – 17 June 1960) was an English film director.  From 1917 to 1948, Rosson directed 61.

La Douleur "(War: A Memoir)" is a controversial, semi-autobiographical work by Marguerite Duras published in 1985 but drawn from diaries that she supposedly wrote during World War II.  It is a collection of six texts recounting a mix of her experiences of the Nazi Occupation of France, with fictional details.  She claims to have "forgotten" ever writing the diary in which she recorded her wartime experiences, but most critics believe that to be a deliberate attempt to confuse autobiography and fiction.  Duras' work is often cited as part of the Nouveau Roman movement which tried to redefine traditional ideas about set categories of books, fiction, non-fiction, biography, autobiography, etc. La Voleuse, meaning 'the thief', is the French title of a 1966 Franco-German film directed by Jean Chapot, with dialogue by Marguerite Duras, that is called Schornstein Nr.  4 in German.

The success of the film, being Rosson's first directorial effort since he co-directed "Her Father's Keeper" in 1917 with his brother Arthur Rosson, won him a long-term contract with Famous Players-Lasky.
