Isabelle Yasmine Adjani (born June 27, 1955) is one of France's best known actresses. She is multilingual, and performs in her native French, English, and German.

Adjani was born in Gennevilliers, Hauts-de-Seine to a Kabyle - Turkish father and a German mother. She was drawn to acting at a young age, playing in amateur theater by the age of twelve. As a fourteen-year-old, she appeared in her first motion picture.
After minor roles in several films, she received positive reviews and much public acclaim for her performance in the 1974 film La Gifle, (The Slap). The following year, she was cast in her first starring role in François Truffaut 's film, L'Histoire d'Adèle H., (The Story of Adele H.) which brought her international acclaim; it resulted in nomination for an Academy Award for Best Actress and offers for roles in Hollywood films.

In 1981 Adjani received the César Award, France's equivalent of an Oscar, for her role in Possession. In 1983, she won the César again, for her vengeful turn in the French blockbuster L'été meurtrier / One Deadly Summer. In 1989, she co-produced and starred in the filmography of tragic French sculptor Camille Claudel, alongside Gerard Depardieu as Rodin. She received her third César Award and second nomination for an Academy Award for Best Actress for her role in the film, which was also nominated for an Academy Award for Best Foreign Language Film. Following this publicity, she was chosen by People magazine as one of the 50 Most Beautiful People in the world. Her unprecedented fourth Cesar win was for the 1994 film La Reine Margot / Queen Margot, an impressive vehicle for Adjani as well as an ensemble epic smoothly directed by opera wunderkind Patrice Chereau.
