Denner was born in 1926 in the city of Tarnów in south-eastern Poland, before emigrating with his family to France at the age of four. During World War II, his family took refuge in Brive-la-Gaillarde, where they were helped by Rabbi David Feuerwerker. During WWII Charles Denner was a Free French partisan in the Vercors mountains and destroyed a nazi SS truck with a grenade; he was wounded and later received the Croix de Guerre for this operation. Passionate about theatre from his childhood, Denner became a student of Charles Dullin, a famous theatre teacher of his time, under whose guidance he remained until 1945. Another great personality of French theatre, Jean Vilar, impressed by Denner’s performance at Les mamelles de Tirésias (The Breasts of Tiresias) called him four years after he left Vilar to join the Théâtre National Populaire (TNP). It was there that he gave some of his earliest stage performances in plays such as Heinrich von Kleist’s Prinz Friedrich von Homburg and Alfred de Musset’s Lorenzaccio, among others.  In 1955, director Yves Allégret offered Denner a small role in La Meilleure part (The Best Part), thus introducing him for the first time to cinema audiences. Two years later, in 1957, he secured another secondary role in Louis Malle’s legendary Elevator to the Gallows, next to Jeanne Moreau, a co-performer of his from the days of the TNP; however, it was not until 1963 that Denner was offered his first leading role by Claude Chabrol in Landru, a film considered by many as his greatest on-screen performance. Despite his growing recognition on the big screen, the stage remained his true passion and the place where he gave his most memorable performances in plays like Molière’s Les Fourberies de Scapin (Scapin’s Schemings) and Brecht’s Drums in the Night.  On 10 September 1995 Denner died of cancer in Dreux, France.
