A singer almost from the time she learned to talk, American actress Shirley Jones was entered by her vocal coach in the Miss Pittsburgh contest at age 18. The attendant publicity led Jones to an audition with Rodgers and Hammerstein for potential stage work. Much taken by Jones' beautifully trained voice, the producers cast her as the leading lady in the expensive, prestigious film production of their theatrical smash Oklahoma! (1955).
In 1956 Jones starred in another Rodgers and Hammerstein film adaptation, Carousel; this and her first film tended to limit her to sweet, peaches 'n' cream roles for the next several years. Thankfully, and with the full support of director Richard Brooks, Jones was able to break away from her screen stereotype with her role as a vengeful prostitute in Elmer Gantry (1960) -- a powerfully flamboyant performance that won her an Academy Award. Alas, filmgoers preferred the nice Shirley, and it was back to goody-goody roles in such films as The Music Man (1962) and A Ticklish Affair (1963) -- though critics heartily praised Jones' performances in these harmless confections. It was again for Brooks that Shirley had her next major dramatic film role, in 1969's The Happy Ending, which represented one of her last movie appearances before her four-year TV stint as the glamorous matriarch of The Partridge Family. This popular series did less for Shirley than it did for her stepson, teen idol David Cassidy, but The Partridge Family is still raking in ratings (and residuals) on the rerun circuit. Her unhappy marriage to the late actor Jack Cassidy long in the past, Jones found domestic stability as the wife of actor/agent Marty Ingels, with whom she recently wrote a refreshingly candid dual biography. ~ Hal Erickson, All Movie Guide.
