The first cut of the film was given a "FSK 16" rating. To achieve a commercially more attractive "12" rating, two shots of violence depicting the kidnapping of Leslie Gine and the death of Lord Harry Chelford under masses of stones, were removed. Both scenes were re-edited into the film for the 2004 German DVD-Release by Universum Film.
This film marks the first in Rialto's Edgar Wallace Series that the director, in this case Franz Josef Gottlieb, was officially credited as a co-writer of the screenplay. He also received a screen credit for Die Gruft mit dem Rätselschloß.
