This film re-teamed director Fritz Lang with art director Erich Kettelhut. Kettelhut had worked for Lang on the first Dr. Mabuse film, "Dr. Mabuse: The Gambler" (1922).
After the blockbuster success of "Goldfinger", this film was re-released in the Unitd States by the Ajax Film Company in 1966. The new posters gave top billing to Gert Frobe and listed him as "Gert Frobe, Mr. Goldfinger".
At the 1:39 mark in the film, "insurance salesman" Hieronymus B. Mistelweig reveals himself as undercover Interpol agent "JTP 23" to Kriminalkommisar Kras by showing Kras his oval-shaped, metal ID disc which is strikingly similar to the warrant discs actually carried by Gestapo agents during the 1930s up until the end of WWII. In fact, real Interpol agents have never used any such discs of that design or type.
This movie broke the record for the longest gap between a movie and its sequel coming 27 years after The Testament of Dr. Mabuse (1933) It broke the record of 22 years set by Die Sklavenkarawane (1958) in 1958. The record was broken again in 1972 by A Very Missing Person (1972)
