British actress Kathleen Byron made her first film Young Mr. Pitt in 1941, shortly after completing her training at the Old Vic. At first a standard-issue ingenue, Byron displayed a dominant willfulness that resulted in roles as schemers and prevaricators. After big-budget films like A Matter of Life and Death (1946) and Black Narcissus (1948) - giving a rivetting performance in the latter as an insane nun - Ms. Byron was consigned to budget-feature films like The Gambler and the Lady (1952) and Profile (1954). She made several pilgrimages to Hollywood in the 1940s and 1950s, but her only American film was MGM's Young Bess (1953), set in England. Kathleen Byron remained in films until the 1980s, though she appeared less frequently and the roles diminished in significance.
