Pierre Clémenti (September 28, 1942 – December 27, 1999) was a notable French actor celebrated for his contributions to cinema and theater. Born in Paris, Clémenti honed his craft in drama before making his film debut in 1960 with a minor role in Yves Allégret's *Chien de pique*, where he shared the screen with Eddie Constantine. His breakout performance came in Luis Buñuel's iconic 1967 film *Belle de Jour*, where he portrayed the charming gangster involved with Catherine Deneuve's character. Clémenti's repertoire included collaborations with esteemed directors such as Luchino Visconti in *The Leopard*, Pier Paolo Pasolini in *Pigsty*, and Bernardo Bertolucci in *The Conformist* and *Partner*.
In 1972, his career faced a significant setback when he was incarcerated for drug-related charges, although he was released after 17 months due to lack of evidence. This experience inspired him to write a book reflecting on his time in prison. Post-release, Clémenti continued to make an impact in cinema, featuring as the optimistic sailor in Dusan Makavejev's controversial *Sweet Movie* and as the alluring saxophonist in Fred Haines's adaptation of Hermann Hesse's *Steppenwolf*.
An influential figure in the French underground film scene, Clémenti directed several experimental films, including *Visa de censure no X*, *New Old*, and *La Revolution ce ne'est qu'un debut, continuons le combat*. He passed away from liver cancer in 1999, leaving behind a rich legacy in the arts.
