Gerald Mohr who plays the murder victim in this film, took over the role of the Lone Wolf after the series continued 3 years later with "The Notorious Lone Wolf"
Gerald Mohr (as Harry Cooper) lights a cigarette with a touch tip lighter, an appliance which had been used in many movies through the 1930s and 1940s. This device can be seen being employed by Humphrey Bogart (as Sam Spade) in the opening scene of "The Maltese Falcon."
