According to director Edgar G. Ulmer, who was working at PRC at the time this film was made, it was originally to be called "Single Indemnity" (it was a virtual copy of the Fred MacMurray/Barbara Stanwyck film Double Indemnity (1944) of a short time earlier). The producers of "Double Indemnity" got wind of it and threatened legal action. PRC then changed the title to "Apology for Murder".
Re-titled, and edited down to less than thirty minutes, it was sold to television in the mid-1950's as part of a syndicated half hour mystery show.
Toni Kirkland (Ann Savage) drives a 1941 Buick convertible; Kenny Blake (Hugh Beaumont) drives a 1939 DeSoto coupe.
The earliest documented telecasts of this film in the New York City area took place Friday 18 February 1949 on the Film Theater of the Air on WCBS (Channel 2), and in Chicago Sunday 5 March 1950 on WNBQ (Channel 5).
