The photo of Mrs. Gordon's (Ida Lupino) deceased husband is actually William Talman, who played Hamilton Burger in Perry Mason (1957).
This story was later redone in 1960 as The Man (1960) (the name of the 1950 Mel Dinelli play the movie was based on). It starred Thelma Ritter and Audie Murphy.
The head of RKO Pictures, Howard Hughes, held the film from release for a year. Robert Ryan felt Hughes, known for his right-wing politics, tried to bury the film because Ryan was publicly active in left-wing politics.
According to an article in the November 15, 1950 edition of "The Hollywood Reporter", Farley Granger was to co-star with Ida Lupino. In the opinion of Eddie Muller on TCM's "Noir Alley", Lupino had dynamic chemistry with co-star Robert Ryan in the prior year's On Dangerous Ground (1951), and she likely considered no one else.
After its success on the CBS radio show "Suspense" in two separate productions in 1945 and 1949, Mel Dinelli turned it into a short story entitled "The Man", which was good enough to be included in several 1949 best short story anthologies. Dinelli then transformed it into a three-act play that opened on Broadway at the Fulton Theatre, 210 W. 46th St., on January 19, 1950 and ran for 92 performances. Many stage versions of the play followed around the world. Ida Lupino saw the big-screen potential and bought the movie rights, hiring Dinelli to do the screenplay adaptation. This meant that Dinelli had successfully parlayed one original story into a radio play, short story, stage play, and screenplay. It was also later adapted for television a few times by other writers.
