In 1958, Cahiers du Cinema (French Film Magazine) voted this movie as one of the ten greatest movies of all time.
According to Michael Wilding's autobiography "The Wilding Way", on one occasion while he and Ingrid Bergman were in the middle of a passionate love scene, Sir Alfred Hitchcock let out a howl of pain, then in the most gentle tone said "Please move the camera a little to the right. You have just run over my foot." The X-ray revealed later that the camera's weight had broken Hitchcock's big toe.
Sir Alfred Hitchcock began to use the "ten-minute take" of continuous one-reel shooting which he had enjoyed refining on Rope (1948), but as the process proved to be far more difficult here than in the enclosed apartment-set drama, only a couple of sequences were ultimately shot that way.
This was Sir Alfred Hitchcock's third movie in a row that failed at the box office. His previous box-office failures were The Paradine Case (1947) and Rope (1948). His next movie, Stage Fright (1950), was also a box-office failure.
Margaret Leighton appeared with her future husband Michael Wilding in this movie. After their marriage in 1964, they worked together several more times, but, by his own admission, Wilding preferred retirement, and was happy just to be a supportive audience member for his wife. In this movie, Michael Wilding played Charles Adare, and Margaret Leighton played Milly.
