Director Mike Mills discusses his new film, 20th Century Women, with Marc Webb. Loosely based on his own childhood, the film follows Dorothea, a single mother raising her adolescent son in Santa Barbara, CA during the cultural revolution of late 1970s. To help steer him through the chaos, Dorothea calls on the help of a punk photographer, a mellow handyman, and her son's best friend to serve as role models.
