[2] Blaise made his acting debut in Louis Malle's 1974 film Lacombe, Lucien.

Malle had been looking for a non-actor to play the titular character in Lacombe, Lucien and was convinced that Blaise, then working as a woodcutter, would bring great authenticity to the role.

(Writing of the film in 1977, Current Biography referred to Blaise as a "real-life Provençal farm boy.")

A year after Lacombe, Lucien was released, Blaise was killed at the age of 20 in a car crash.

Accompanied by two friends he had brought along for company, Blaise lost control and crashed against a plane tree on the route de Laujol between Moissac and Durfort-Lacapelette, where he lived with his parents.
