As of her youth, Sara Forestier revealed an artistic temperament, loving to write, to paint, and especially to act. When she was thirteen and half years old, she decided to accompany one of her friends to an audition. She took the audition with brilliance, and her career in the acting started here. She met an artistic agent and obtained minor parts in movies and TV movies until L'Esquive. Whereas Abdellatif Kechiche didn't want "true actors" for his movie, she succeeded in convincing by her talent and obtained the leading female role of the film. The movie and her performance were cheered. Now, she continues to shoot in varied films and will have her second leading role in a film adaptation of the novel of Lolita Pille, Hell, at the side of Nicolas Duvauchelle.
