Rhys Williams was a Welsh character actor in films and television. He made his film debut in "How Green Was My Valley" (1941), based on Richard Llewellyn's novel of the same name. Although the story takes place in the coal mining valleys of south-east Wales, Williams was the only Welsh actor in the cast. In 1945, Williams played the role of Dr. McKay in the "The Bells of St. Mary's", starring Bing Crosby and Ingrid Bergman. Williams moved to the USA and died in Santa Monica, California in 1969.
