This was the 13th and final film in RKO's long-running Falcon franchise. After this, the rights to the name and character of the Falcon were licensed to a low end company called Film Classics, which produced three additional Falcon films before abandoning the series.

The train going to Florida is depicted as having the Pennsylvania Railroad steam locomotive #3768, a K4 model with a streamlined shroud designed by Raymond Loewy. This famous locomotive can also be seen in La cible vivante (1945) and Le rapt du rapide 5 (1941) - the train it was usually associated with as well. It was nicknamed "The Torpedo". It was built by the railroad in its own works in Altoona, Pennsylvania in 1920. The streamlining was applied in 1936 and it was featured at the 1936 and 1939 World Fairs. The cladding was removed around 1950 because it impeded maintenance. It was scrapped in 1953.
In New York, The Falcon's car is a 1941 Cadillac Series 62 convertible. In Florida, he down-scales and rents a 1941 Mercury Eight Club convertible.
