Actor Selma Blair first appears in the new documentary about her struggles with multiple sclerosis (MS) dressed as Norma Desmond, the reclusive, washed-up silent-film star played by Gloria Swanson in Sunset Boulevard. In a sparkly turban, a floor-length leopard-print dress and her cane by her side, Blair displays a jokey self-awareness about her public image, especially since announcing her diagnosis in October 2018.
