Marie-Pierre Casey went on stage to play in several plays by Jean-Michel Ribes at the Théâtre de la Ville and the Gaîté-Montparnasse during the 1970s. In 1960, she played a nurse in Jean Bastia's Certains l'aiment froide and, in 1967, the cashier of the Royal Garden in Jacques Tati's Playtime. In 1970, on the big screen, she played notable supporting roles in Les Choses de la vie by Claude Sautet and in La Peau de Torpedo by Jean Delannoy.
