Question: How long had 20th Centuy Fox been established when they signed Holm to a movie contract? Passage:After she starred in the Broadway production of Bloomer Girl, 20th Century Fox signed Holm to a movie contract in 1946. She made her film debut that same year in Three Little Girls in Blue, making a startling entrance in a "Technicolor red" dress singing "Always a Lady," a belting Ado Annie-type song, although the character was differenta lady. In 1947 she won an Oscar and Golden Globe for Best Supporting Actress in Gentleman's Agreement. However, after another supporting role in All About Eve, Holm realized she preferred live theater to movie work, and only accepted a few select film roles over the next decade. The most successful of these were the comedy The Tender Trap (1955) and the musical High Society (1956), both of which co-starred Frank Sinatra. She starred as a professor-turned-reporter in New York City in the CBS television series Honestly, Celeste! (fall 1954) and was thereafter a panelist on Who Pays? (1959). She also appeared several times on ABC's The Pat Boone Chevy Showroom.
