Witness to Murder is a 1954 American film noir crime drama directed by Roy Rowland and starring Barbara Stanwyck, George Sanders, and Gary Merrill. While the film received moderately positive reviews, it ended up as an also-ran to Alfred Hitchcock's somewhat similar Rear Window, which opened less than a month later. The latter picture was a box-office hit.

George Henry Sanders was a British actor and singer whose career spanned over 40 years. His heavy, upper-class English accent and smooth, baritone voice often led him to be cast as sophisticated but villainous characters. He is remembered for his roles as wicked Jack Favell in Rebecca (1940), Scott ffolliott in Foreign Correspondent, The Saran of Gaza in Samson and Delilah, theater critic Addison DeWitt in All About Eve, Sir Brian De Bois-Guilbert in Ivanhoe (1952), King Richard the Lionheart in King Richard and the Crusaders (1954), Mr. Freeze in a two-part episode of Batman (1966), and the voice of Shere Khan in Disney's The Jungle Book (1967). Fans of radio detective stories know Sanders as Simon Templar, The Saint, (1939–41), and the suave crimefighter The Falcon (1941–42).
