A gauzy and sometimes dopey romanticization about the unusual 16-year love affair between the celebrated French writer Marguerite Duras and a man nearly 40 years her junior. While Aymeric Demarigny is forgettable as the young man on whose book the movie is based, Jeanne Moreau, as Duras, is a canny lioness, demanding obeisance to her own legendary stature in world cinema.
