“Larry [Laurence Olivier] saw me when I was at the Mercury, doing a revival of the Mask of Virtue, the play in which Vivien Leigh had made her name. Apparently they had come to see the play and then asked me to do a test for Henry V - I didn't even know Larry was filming it. Larry also asked Janet Burnell who was playing my mother to test for the Queen, and we both got the parts.”
