The son of famed French director Claude Berri and nephew of producers Jean-Pierre Rassam and Paul Rassam, Julien Rassam trained as a filmmaker at New York University with the expectation of both directing and acting. (He directed the 1991 short "Jour de Colere.") The dark-haired, charismatic actor is perhaps best known to American audiences for his portrayal of the youngest of the murderous brothers in Patrice Chereau's "Queen Margot/La Reine Margot" (1994), the celebrated French film about the events leading to the St. Bartholomew Day massacre. Rassam made his feature film debut in the title role of a ne'er-do-well who insinuates himself into his friends' lives in Bruno Nuytten's "Albert Suffers" (1992). He followed with small roles in Claude Miller's "The Accompanist" and Laetitia Masson's "Nulle part" (both 1992) and played the leading role of angst-driven teen in Chantal Akerman's "Portrait of a Young Girl at the End of the 1960s in Brussels" (1994). In 1997, Rassam made his first English-language film, the horror sequel "An American Werewolf in Paris."
