Dheepan is a 2015 French crime drama film directed by Jacques Audiard and co-written by Audiard, Thomas Bidegain, and Noé Debré. The film was partly inspired by Montesquieu's Persian Letters. The film tells the story of three Tamil refugees who flee the civil war-ravaged Sri Lanka and come to France, in the hope of reconstructing their lives. The film's title character, played by Antonythasan Jesuthasan, was a former Tamil Tiger child soldier. The film won the Palme d'Or at the 2015 Cannes Film Festival. It was shown in the Special Presentations section of the 2015 Toronto International Film Festival.
Audiard started making the movie with the intent to make a variation of Sam Peckinpah's 1971 thriller Straw Dogs. But he wanted to set it in a community that no one in France knew much about. He and his writing partner, Thomas Bidegain, decided on the Tamils. During filming, Mr. Jesuthasan sometimes made corrections for accuracy.
