Following the production, Brauner was preparing for a remake of "The Testament of Dr. Mabuse" when Lang approached him with the idea of adding a new original film to the series. The result was "The Thousand Eyes of Dr. Mabuse" (1960), whose success led to a series of new Mabuse films, which were produced by Brauner (including the remake of "The Testament of Dr. Mabuse"), though Lang did not direct any of the sequels. Lang was approaching blindness during the production, and it was his final project as director.
