This film features the iconic Bradbury Building at 304 S. Broadway as the location of Griff Marat's office. Out of his office window can be seen the old Hall of Records Building at 220 N. Broadway (demolished 1973), which is about 0.4 miles away.
In Samuel Fuller's original script, the film ended with a violent rebellion by Marat against the system that kept him and Marsh apart. The studio had National Velvet (1944) scriptwriter Helen Deutsch step in to pen a soft-suds rewrite.
Cornel Wilde and Patricia Knight were married at the time this film was made. They would divorce in 1951.
In many of Sam Fuller's screenplays he features a main character named "Griff", including in The Naked Kiss (1964), The Baron of Arizona (1950), House of Bamboo (1955), Forty Guns (1957), and The Big Red One (1980). Griff was the name of a soldier Fuller served with in the U.S. Army and who was killed overseas during World War 2.
