Unfulfilled plans to showcase her in color, proposed between 1938-53, included these eventually produced films: First Love (1939) (which starred her in black and white), Phantom of the Opera (1943) (Susanna Foster in Technicolor), Up in Central Park (1948) (in black and white), A Connecticut Yankee in King Arthur's Court (1949) (Rhonda Fleming in Technicolor), Melba (1953) (Patrice Munsel in Technicolor), Kiss Me Kate (1953) (Kathryn Grayson in Anscocolor), The Student Prince (1954) (Ann Blyth in Anscocolor) and Song of Norway (1970) (Florence Henderson in Color by DeLuxe). As reported by A.H. Weiler in "The New York Times" on 8/3/1947, Deanna Durbin was being offered a black-and-white filming in Britain of The Beggar's Opera (1953), which ultimately featured Dorothy Tutin portraying Polly Peachum in Technicolor.
