An actor and director born in Paris in 1946, Didier Sandre trained in the Stanislavski method before joining Catherine Dasté's young-audience company in 1968. He took part in the adventure of the Théâtre Nanterre-Amandiers alongside Patrice Chéreau, who directed him in Ibsen's Peer Gynt, Genet's The Screens and Marivaux's La Fausse Suivante. In 1987, Antoine Vitez entrusted him with the role of Don Rodrigue in Paul Claudel's The Satin Slipper, premiered in the Cour d'honneur of the Palais des papes — a landmark performance saluted by the Syndicat de la critique.
Over his career, he has played under the direction of Luc Bondy, Jean-Pierre Vincent, Giorgio Strehler, Hans Peter Cloos, Bernard Sobel and Christian Schiaretti, among others. In 1996 he received the Molière Award for Best Actor for Oscar Wilde's An Ideal Husband and in 2021 the Syndicat de la critique prize for his solo show La Messe là-bas, which he conceived around the words of Paul Claudel.
He joined the Comédie-Française in 2013 and was appointed sociétaire in 2020. There he has appeared notably in The Damned directed by Ivo van Hove, in Marivaux's Le Petit-Maître corrigé directed by Clément Hervieu-Léger and in Le Bourgeois gentilhomme directed by Valérie Lesort and Christian Hecq. A celebrated narrator, he regularly appears in works combining music and text: Stravinsky's L'Histoire du soldat, Debussy's The Martyrdom of Saint Sebastian, Beethoven's Egmont, Prokofiev's Peter and the Wolf and Grieg's Peer Gynt.
