India Song is a 1975 French drama film written and directed by Marguerite Duras. It stars Delphine Seyrig, Michael Lonsdale, Mathieu Carrière, Claude Mann, Vernon Dobtcheff, Didier Flamand and Claude Juan. 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 at the Château Rothschild.
