Diana Lewis on AllMovie

The daughter of vaudevillians, Diana Lewis made her screen debut as bird-brained preteen Miss Dunk in W.C. Fields' It's a Gift (1934), disrupting Fields' early-morning slumber with her inane, top-at-the-lung questions. She then quit acting to attend high school, but by 1939 was back before the cameras, this time as an MGM contractee. Her best-known role at Metro was as the antiseptic heroine in the Marx Brothers 'Go West (1940). Known to her friends as "Mousie," Lewis began losing interest in pursuing a film career when, in 1940, she married MGM star William Powell. Retiring from the screen in 1943, Diana Lewis happily devoted herself to her marriage and social obligations; she remained Mrs. William Powell until her husband's death in 1984.
