Apparently, she first indicated her talent on radio as a child, and graduated to roles with the Abbey Players. In 1939, she joined Charles Laughton in Hollywood playing a stunning Esmeralda to his celebrated Hunchback of Notre Dame in a haunting studio evocation of medieval Paris, one of the best films William Dieterle ever made during his Hollywood years. John Ford cast her in the key role of Angharad, opposite Walter Pidgeon, Donald Crisp and Sara Allgood in his moving studio recreation of a Welsh coal mining community, How Green Was My Valley. There followed further substantial roles at Fox and RKO (The Black Swan for Henry King; The Immortal Sergeant for John M. Stahl, This Land is Mine for Jean Renoir; The Fallen Sparrow for Richard Wallace; The Foxes of Harrow, again for Stahl; the very funny Clifton Webb vehicle Sitting Pretty (Walter Lang, USA, 1948) with Webb as the deliciously acerbic Mr Belvedere).
