Nadine Nortier is a non-professional French actress, known primarily for her sole and celebrated cinematic role in the film *Mouchette* (1967) by director Robert Bresson. Chosen by Bresson according to his method of using 'models' rather than professional actors, Nortier portrayed the eponymous character, a tormented teenage girl whose tragic story is at the center of the narrative. Her performance, intense and free of artifice, is considered one of the most powerful and memorable in the history of auteur cinema, contributing decisively to the film's critical success, which received the OCIC Award at the 1967 Cannes Film Festival. After this experience, Nadine Nortier did not pursue an acting career, retiring to private life and leaving this iconic performance as the sole testament to her talent. Her figure thus remains inextricably linked to a work that has secured her a permanent place in cinematic history.
