There’s a scene in Mike Mills’ 20th Century Women that will be remembered as the film’s funniest, a moment that perfectly captures the essence of its trio of titular female characters. With a tinge of annoyance, Annette Bening’s Dorothea calls out her tenant Abbie, a red-haired punk, for dozing off on the table during a dinner party. “I’m menstruating,” Abbie grumpily retorts. Much to Dorothea’s embarrassment, Abbie then prompts the men at the table to confidently utter the word “menstruation.” Capping off the scene, Elle Fanning’s rebellious 16-year-old Julie breaks into an awkward story about losing her virginity. Three women across three generations, all with varying barometers of what it means to be a woman, and what it means to harness femininity.
