She debuted onscreen at age 14 in 1931, appearing in two or three more films before her first important role, in Marc Allegret's Entree des Artistes/The Curtain Rises (1938). In the '40s she was one of the top French film stars. After 1950 she appeared onscreen only rarely, devoting herself to writing novels, plays, and scripts. She appeared in one film based on one of her novels, The Bride Is Much Too Beautiful (1956), for which she wrote the dialogue. Her first husband was actor Pierre Brasseur. She is married to director Philippe Agostini.
