Montand achieved international recognition as a singer and actor, starring in many films. His recognizably crooner songs, especially those about Paris, became instant classics. He was one of the best known performers at Bruno Coquatrix's Paris Olympia music hall, and toured with musicians including Didi Duprat. In October 1947, he sang "Mais qu'est-ce que j'ai ?" (music by Henri Betti and lyrics by Édith Piaf) at the Théâtre de l'Étoile. Betti also asked him to sing "C'est si bon" but Montand refused. Following the success of the recording of this song by the Sœurs Étienne in 1948, he decided to record it. Montand was also very popular in the Soviet Union and Eastern Europe, where he did a concert tour in 1956-57.
During his career, Montand acted in American motion pictures as well as on Broadway. He was nominated for a César Award for Best Actor in 1980 for I comme Icare and again in 1984 for Garçon! In 1986, after his international box-office draw power had fallen off considerably, the 65-year-old Montand gave one of his best remembered performances, as the scheming uncle in Jean de Florette, co-starring Gérard Depardieu, and Manon des Sources (both 1986), co-starring Emmanuelle Béart. The film was a worldwide critical hit and revived Montand's profile in the US, where he made an appearance on Late Night with David Letterman.
