Langmann was born in Paris, France, the son of Anne-Marie Rassam and film director
Claude Berri. His uncle was the late producer
Jean-Pierre Rassam and his brother was the late French actor
Julien Rassam. Both his mother and his brother committed suicide, in 1997 and 2002, respectively, while his father died of a stroke in 2009. He has a younger half-brother from his father's later relationship, Darius Langmann. His father Claude Berri was
Jewish, and his mother Anne-Marie Rassam, who was born in
Lebanon, was
Syrian Christian. During the filming of
Asterix at the Olympic Games, Langmann was arrested for employing prostitutes and purchasing narcotics. In 2008, Langmann was sentenced to four months in prison for assaulting his long-term girlfriend Frédérique, with whom he had a daughter in 2002. Langmann married French journalist Céline Bosquet on 21 June 2013. During the years that followed his father's death, Langmann became involved in a legal dispute with his father's last partner
Nathalie Rheims, his father's second wife Sylvie Gautrelet, and his half-brother Darius (Gautrelet's son) whom he all accused of misappropriating the family assets. In July 2015, Langmann filed a complaint against Darius, citing
theft of works of art from their father's collection. In March 2025, Darius, Rheims, Gautrelet and several other people were indicted for
conspiracy to commit theft and
tax evasion. ==Filmography==
