The son of French film star Gerard Depardieu has died in a Paris hospital from a bout of acute pneumonia.
Guillaume Depardieu, who was also an actor, was 37.
A spokesman for Artmedia, Depardieu senior's agency, said he had contracted a virus that developed into "a devastating case of pneumonia". He died on Monday.
Depardieu, won the French version of an Oscar, a Cesar, for "best new male talent" in 1996 for his role in a black comedy Les Apprentis, but he was also famous for a turbulent private life.
He served his first prison sentence at the age of 17 and returned to jail when he was 22 for heroin trafficking.
He badly injured his knee in a motorcyle accident in 1995, after which he caught a superbug in hospital and had part of one leg amputated.
