The Balboa Island Car Ferry, used by Joan Bennett and James Mason, still travels the 1000 feet distance between Balboa Island and the Balboa Peninsula.
Walter Wanger, who produced "The Reckless Moment", and Joan Bennett were married from 1940 until 1965. In 1951 Wanger shot Bennett's agent, Jennings Lang, apparently based on the assumption of a romantic involvement between the two.
For this movie and others made in Hollywood, the director is listed as Max Opuls; however, for his movies made in Europe he is credited as Max Ophüls. His surname at birth was Oppenheimer.
James Mason said that after Columbia refused to give director Max Ophüls the permission to light simultaneously two large and separate sets, and to allow a long dolly shot from one place to the other, he thought that "Ophüls could not smile anymore from this day."
