For nearly 50 years everybody who was anybody in the British theatre passed before the lens of Angus McBean - Gielgud, Olivier, Thorndike, Coward. He was known as the photographer who resolutely flattered his sitters. Tonight, after a ten-year absence, McBean demonstrates his skill with his old friend Sir Ralph Richardson. He discusses for the first time his astonishing surreal pictures of the 30s and 40s, and photographer Jo Spence faces up to herself and looks beyond the smiling pictures in her own family album.
