From 1930 until her death, she only performed in five more movies, including "Our Hearts Were Young and Gay" (1944), which was a hit for Paramount. Director Otto Preminger cast Dorothy in his 1946 film, "Centennial Summer", and Mae Marsh appears in the film in one of her many bit parts. In the 1951 release "The Whistle at Eaton Falls", a film noir drama film produced by Louis de Rochemont, Dorothy portrays the widow of a mill owner. On television during this period, she also made several appearances in anthology television series. Her final film role was in 1963 in another Otto Preminger production, "The Cardinal", in which she plays the mother of the title character.
