Following World War II, Juliette Gréco discovers the intellectual and artistic exaltation of Paris' Left Bank and appears in a few stage productions and radio shows. Promptly becoming the muse of Saint-Germain-des-Prés, she belongs to the existentialist movement that discusses poetry, philosophy and listens to jazz in the area's caves. Juliette Gréco sings the texts of her intellectual entourage such as Boris Vian and Jean-Paul Sartre while she falls in love with Miles Davis – a relationship she has to renounce to because of America's segregation laws. At the very end of the 1950s, she engages a relationship with Darryl Zanuck who makes her star in some of the films he produces such as Le Soleil se Lève Aussi, in 1957 and Le Grand Risque, in 1961. In the 1960s, she is back in France where she appears in the television series Belphégor ou le Fantome du Louvre and continues to sing thoughtful tunes written by Serge Gainsbourg or Jacques Brel. The elegant and mysterious lady in black who cheekily sang a song urging to undress her remains an icon of France's popular mythology, a muse whose voice turned Jean-Paul Sartre's 'words into precious gems' and who incarnates Hedi Slimane's contemporary vision of the Saint Laurent subversive woman.
