Mary Forbes on AllMovie

Born on New Year's Day in 1883 (some sources say 1880), British actress Mary Forbes was well into her stage career when she appeared in her first film, 1916's Ultus and the Secret of the Night. By the time she made her first Hollywood film in 1919, the thirtysomething Forbes was already matronly enough for mother and grande-dame roles. Her most prolific movie years were 1931 through 1941, during which time she appeared in two Oscar-winning films. In Cavalcade (1933), she had the small role of the Duchess of Churt, while in You Can't Take It With You (1938) she was assigned the more substantial (and funnier) part of James Stewart's society dowager mother. Mary Forbes continued in films on a sporadic basis into the '40s, making her screen farewell in another Jimmy Stewart picture, You Gotta Stay Happy (1948).
