After 1953's I Confess, Hitchcock planned to film The Bramble Bush, based on the 1948 novel by David Duncan, as a Transatlantic Pictures production, with partner Sidney Bernstein. However, there were problems with the script and budget, and Hitchcock and Bernstein decided to dissolve their partnership. Warner Bros. allowed Hitchcock to scrap the movie, and begin production on Dial M for Murder.
Mark's name was changed for the film; in the original play, he was Max Halliday. Actors Dawson and Williams reprise their Broadway roles as Swann/Captain Lesgate and Inspector Hubbard, respectively.
Alfred Hitchcock's cameo is a signature occurrence in most of his films. In Dial M for Murder, he can be seen thirteen minutes into the film, in a black-and-white reunion photograph, sitting at a banquet table among former students and faculty.
