Netflix's Ratched welcomes an engaging cast of characters to tell the story of Nurse Mildred Ratched (Sarah Paulson), and one of Lucia State Hospital's most infamous residents is Charlotte Wells (Sophie Okonedo), a character struggling with multiple personality disorder. Throughout the series, Okonedo channels several different personas, including a boxer, a baby, and the hospital's own Dr. Hanover (Jon Jon Briones). It's one of several impressive performances the actress has delivered on the screen and stage throughout her career.
