Trailblazing comedian Gilda Radner is the subject of this effusive documentary, grounded in the wise choice to have much of the story told by Radner herself. First-time director Lisa D’Apolito interweaves Radner’s personal writings and audiotape recordings with photographs and home videos to create a moving portrait of the original Saturday Night Live cast member, which stretches from Radner’s childhood in 1950s Detroit to her death from ovarian cancer in 1989. Famous fans like Melissa McCarthy and Amy Poehler read aloud from her diary with a mix of awe and delight while her contemporaries, including Martin Short and Lorne Michaels, share their memories and insights into her too-brief life and career. Fittingly though, it’s Radner’s voice—especially when describing her struggles with food, fame, and men—that shines brightest.
