Simone Signoret. Actress: Diabolique. The face of Simone Signoret on the Paris Metro movie posters in March looked even older than her 61 years. She was still a box-office draw, but the film L'Étoile du Nord () would be her last theatrical release; she played the landlady. Signoret had a long film apprenticeship during World War II, mostly as an extra and occasionally getting to.
