**Jacques Doniol-Valcroze (1920-1989)** was a multifaceted figure in French cinema: critic, director, screenwriter, and actor. He was co-founder of *Cahiers du Cinéma* and a key figure in the Nouvelle Vague.

As an actor, he often played intellectual, bourgeois, refined, and sometimes enigmatic or melancholic characters. His acting was characterized by subtle intensity and psychological depth. He starred in many of his own films, such as *L'Eau à la bouche* (1960) and *Le Viol* (1967).

But he was also appreciated by other prominent directors. Among his most significant performances are those in *L'Immortelle* (1963) by Alain Robbe-Grillet and, later in his career, the memorable role of Count Tullio Hermil in *L'Innocente* (1976) by Luchino Visconti. His presence on screen was always distinctive, helping to define a certain type of intellectual actor in French arthouse cinema.
