Eve Channing

Eve Channing has the distinction of being the only female starring in the male dominated space of Sleuth (1972) but also, as one of the four credit only actors who does not exist, actually she's the only of the group who sort of makes an appearance in the movie thanks to a portrait displayed on a room. Channing's face was modeled after actress Joanne Woodward; and her stage name comes from the surname of the main characters of the classic All About Eve (1950), which was also directed by Joseph L. Mankiewicz.
