Sylvie Testud (born 17 January 1971) is a French actress, writer, and film director, whose film career began in 1991. She won the César Award for Most Promising Actress for Murderous Maids (2000), the César Award for Best Actress for Fear and Trembling (2003), and the European Film Award for Best Actress for Lourdes (2009). Her other film roles include Beyond Silence (1996), La Vie en Rose (2007), and French Women (2014).
She grew up in the La Croix-Rousse quarter of Lyon, France. This was an area with many Portuguese, Spanish and Italian immigrants. Her mother immigrated from Italy in the 1960s. Her French father left the family when Sylvie was just two years old.
In 1985, when she was 14, she saw Charlotte Gainsbourg in her role of the complex young girl in L'Effrontée, a film directed by Claude Miller, identified with Gainsbourg, and so took drama classes in Lyon with the actor and director Christian Taponard. In 1989, she moved to Paris and spent three years at the Conservatoire (CNSAD). In the early and mid 1990s, she landed her first small roles in films like L'Histoire du garçon qui voulait qu'on l'embrasse, directed by Philippe Harel, and Love, etc., directed by Marion Vernoux. In 1997 she had great success in Germany with Caroline Link's Jenseits der Stille for which she learned German, sign language, and the clarinet. In 1998 she had her first major role in French cinema playing Béa in Thomas Vincent's Karnaval. In 2000 she starred in Chantal Akerman's La Captive, an adaptation of La Prisonière, the fifth part of Marcel Proust's À la recherche du temps perdu. In 2001 she won the César Award for Most Promising Actress for her portrayal of Christine Papin, one of the Papin sisters, in Les Blessures assassines (English title: Murderous Maids). The story concerned a young servant woman found guilty of the murder, with her sister's help, of her employer's wife and daughter; it had made sensational headlines in France in 1933.
