The director of controversial cult film Man Bites Dog has died aged 38, according to the Hollywood Reporter.
A family statement said Belgian Remy Belvaux died in Orry-la-Ville, north of Paris, but no cause of death was given.
Belvaux also starred in Man Bites Dog, a blackly comic mock-documentary about a mass murderer that won several awards but aroused considerable controversy.
He never made another feature film, but turned to directing commercials which won several industry awards.
"He leaves us one masterpiece and tons of regrets," the family statement was quoted as saying.
Man Bites Dog won two awards at the 1992 Cannes Film Festival.
Benoit Poelvoorde, who co-wrote and co-produced the film and played the serial killer in his first feature film role, has become a major cinema star in France.
