Sleuth (1972 film) as a full partner. The likeness of actress Joanne Woodward was used for the painting of Marguerite Wyke. The production team intended to reveal as little about the movie as possible so as to make the conclusion a complete surprise to the audience. For this reason there is a false cast list at the beginning of the film which lists fictional people playing roles that do not exist. They are Alec Cawthorne as Inspector Doppler, John Matthews as Detective Sergeant Tarrant, Eve Channing (named after the characters Eve Harrington and Margo Channing from Mankiewicz's 1950 film "All About Eve") as
Bette Davis film, "Lady for a Day"), based on a story by Damon Runyon. She accepted her next role, in the Grand Guignol horror film "What Ever Happened to Baby Jane?" (1962), after reading the script and believing it could appeal to the same audience that had recently made Alfred Hitchcock's "Psycho" (1960) a success. She negotiated a deal that would pay her 10% of the worldwide gross profits in addition to her salary. The film became one of the year's biggest successes. Davis and Joan Crawford played two aging sisters, former actresses forced by circumstance to share a decaying Hollywood mansion.
