Past and present collide in an increasingly complicated and highly entertaining fashion in Justine Triet’s intricate study of the professional and personal masks we wear as we perform our daily lives. Psychotherapist Sibyl (Virginie Efira) abruptly decides to leave her practice to restart her writing career—only to find herself increasingly embroiled in the life of a desperate new patient: Margot (Adèle Exarchopoulos), a movie star dealing with the aftermath of a traumatic affair with her costar, Igor (Gaspard Ulliel), while trying to finish a film shoot under the watchful eye of a demanding director (Toni Erdmann’s Sandra Hüller, splendidly high-strung), who happens to be Igor’s wife. Sibyl, negotiating her own past demons, makes the fateful decision to use Margot’s experiences as inspiration for her book, as boundaries of propriety fall one after another. As she proved in her previous film In Bed with Victoria, which also starred the magnificently expressive Efira, Triet is a master at creating heroines of intense complexity, and of maintaining a tricky balance between volatile drama and sly comedy. An NYFF57 selection. A Music Box Films release.
