Barbara Lawrence already had 10 years' experience as a photographer's model when, at age 17, she appeared in her first film, Billy Rose's Diamond Horseshoe (1945). She completed her studies at UCLA while co-starring in such 20th Century-Fox productions as Margie (1946) and Unfaithfully Yours (1948). Only occasionally a leading lady, Lawrence was generally cast as the heroine's best friend -- or, if there was a man involved, worst enemy. Lawrence's best-known screen role was the giggling Gertie Cummings in Oklahoma (1955), a part she had previously played on stage. In 1977, an unexpected biography appeared, Jim Connor's Hollywood Starlet: The Career of Barbara Lawrence. ~ Hal Erickson, All Movie Guide
