Catherine Lacey (6 May 1904, London - 23 September 1979, London) was an English actress who made her film debut in 1938 as the secretive nun who wears high heels in the Alfred Hitchcock film The Lady Vanishes (1938). She was an established stage character player before she was 30. Her film roles were as neurotics or eccentrics, usually playing spinsters or unpleasant spouses.

Lacey had roles in major films like I Know Where I'm Going! (1945), The October Man (1947) and The Fighting Prince of Donegal (1966) in which she played Queen Elizabeth I. At the end of her career, she played in horror films opposite Boris Karloff in Michael Reeves's The Sorcerers and as the mysterious Haiti in The Mummy's Shroud, both in 1967. She was married to and divorced from the British actors Roy Emerton and Geoffrey Clark.

Gavin Lambert (23 July 1924 – 17 July 2005) was a British-born screenwriter, novelist and biographer who lived for part of his life in Hollywood. His writing was mainly fiction and nonfiction about the film industry.

Lambert was educated at the independent school Cheltenham College, Cheltenham, Gloucestershire, England, and at Magdalen College, Oxford, where one of his professors was C. S. Lewis. At Oxford, he befriended filmmakers Karel Reisz and Lindsay Anderson, and they founded a short-lived but influential journal, Sequence, which he co-edited with Anderson. Lambert eventually left Oxford without obtaining a degree. From 1949 to 1955 he edited the periodical Sight and Sound, again with Anderson as a regular contributor. At about the same time Lambert was deeply involved in Britain's Free Cinema movement which called for more social realism in contemporary movies. He also wrote film criticism for The Sunday Times and The Guardian. In 1957 he moved to Hollywood, California, to work as a screenwriter and personal assistant to director Nicholas Ray, whose movie Bitter Victory (1957) he co-wrote. He claimed to be Ray's lover for a period of time.
