The film critic Richard Brody regards Josephine Decker as one of the best directors of her generation, and picked her 2018 film “Madeline’s Madeline” as his favorite of the year. Decker, he says, reinvents “the very stuff of movies—image, sound, performance—with each film.” Decker’s new film is “Shirley,” starring Elisabeth Moss as the unique horror author Shirley Jackson. In it, Decker dives deeper into the themes that have also shaped her previous works: the creative drives and the relationships of women. Decker tells Brody that, though the film may be a step toward mainstream, she remains guided by “poetic logic.”
