Jeanne Moreau is a living legend in French cinema and a star all around the world.
In the late 1950s, Mademoiselle Moreau caused many a sensation with spellbinding performances in films such as Elevator To the Gallows and The Lovers, both directed by Louis Malle. The latter movie was so controversial that she was soon being called the next Brigitte Bardot (whom she would work with in 1965's Viva Maria!, also directed by Louis Malle).
Instead, she became Jeanne Moreau. :-)
Her performance as the elusive Catherine in François Truffaut's 1962 French New Wave classic Jules and Jim made her a legend and put her in very much demand. Soon she was working with every movie director that mattered, and a few that didn't. Orson Welles (who directed her in 1962's The Trial, 1965's Chimes at Midnight, and 1968's The Immortal Story) declared her to be "the greatest actress in the world."
Jeanne Moreau has also been a singer, performing the song "Le Tourbillon" ("The Whirlwind") in Jules and Jim, and she even sang with Frank Sinatra at Carnegie Hall in New York.
Jeanne Moreau (shown above in 2006) remains active as an actress into her eighties, having most recently appeared in Une estonienne à Paris (An Estonian Woman In Paris), in 2012.
