Answer
Jean Arthur, the original Billie Dawn in George S. Kaufman and Moss Hart's play "Born Yesterday," left the Broadway production in 1946 due to exhaustion. Judy Holliday, a relatively unknown actress at the time, was chosen as her replacement and made her debut in the role on January 14, 1946. Holliday's portrayal of the ditzy showgirl turned savvy political activist garnered critical acclaim and helped launch her successful acting career.
