The brief shots of female nudity during the striptease scenes at the Highlow Club, and the overall "extreme" psychological motive of the villain led to a FSK 18 rating for the uncut version. Several attempts to re-cut the film in order to get a lower rating failed and eventually, the film was released theatrically in its uncut version - and became one of the least commercially successful films of the Edgar Wallace series to that date.
The exterior shots were filmed entirely in Denmark. This was the third and last German Edgar Wallace Film to do so, following the first two installments of the series, "Der Frosch mit der Maske"(1959) and "Der rote Kreis" (1960).
First film of Rialto Film's Edgar Wallace series to receive an 18 Rating. Many blamed the film's commercial failure on this rating as the series was intended to mainly attract young audiences.
