<P> Since Betty Grable was not available to play Miss Adelaide, Goldwyn cast Vivian Blaine, who had originated the role onstage . Marilyn Monroe had wanted the part of Adelaide, but a telephone request from her did not influence Joe Mankiewicz, who wanted Blaine from the original production . </P> <P> Goldwyn wanted Grace Kelly for Sarah Brown, the Save - a-Soul sister . When she turned the part down because of other commitments, Goldwyn tried Deborah Kerr, who was also unavailable . The third choice was Jean Simmons, who had recently played opposite Brando in Désirée . Goldwyn was surprised by Simmons' sweet voice and strong acting and ultimately believed the love story worked better in the film than onstage . "I'm so happy" he said after seeing the rushes one day "that I couldn't get Grace Kelly". Director Joe Mankiewicz later called Simmons "the dream...a fantastically talented and enormously underestimated girl . In terms of talent, Jean Simmons is so many heads and shoulders above most of her contemporaries, one wonders why she didn't become the great star she could have been ." </P> <P> The musical numbers performed by Jean Simmons and Marlon Brando were sung by the actors themselves, without dubbing by professional singers . </P> <P> In addition to Blaine, Stubby Kaye, B.S. Pully, and Johnny Silver all repeated their Broadway roles in the film . </P>
