Jean-Marc Barr (born 27 September 1960) is a French American film actor and director. In 1991, Barr starred in Danish director Lars von Trier's Europa, marking the beginning of a long friendship (he is the godfather of von Trier's children) as well as a significant professional relationship. He went on to appear in von Trier’s Breaking the Waves (1996), Dancer in the Dark (2000), Dogville (2004), Manderlay (2005), The Boss of It All (2006) and Nympho maniac (2013). In 2005 he starred in the French film Crustacés et Coquillages. In 1999 he starred in the French cinéma du corps/cinema of the body drama film, Don't Let Me Die on a Sunday (French: J'aimerais pas crever un dimanche), directed by Didier Le Pêcheur. Barr's collaboration with von Trier put him on track to start directing his own work. He debuted in 1999 as a director, screenwriter and producer with the intimate love story Lovers. The film became the first part of a trilogy; the films that followed were the drama Too Much Flesh (2000) and the comedy Being Light (2001), which he co-directed with Pascal Arnold. Barr and Pascal also directed the 2006 film Chacun sa nuit (eng: One to another), where they first discovered Lizzie Brocher, Arthur Dupont and Karl E. Landler. This was followed by another collaboration in 2012, Sexual Chronicles of a French Family.
