The Thousand and One Lives of Doctor Mabuse

An idea for the 3rd film, way back in 2012, was that Christina Novello would come into possession of the Necronomican and would unleash an alien invasion heralded by the arrival of Wilbur Whatley upon Etiopomar. Another idea was that the film would draw upon Fritz Lang's WOMAN IN THE MOON for inspiration. At one point, the film revolved around the Three Mothers and Lady Levana and psychic investigator Thomas Carnacki solving a mystery which would involve Mabuse to a small degree. The main story idea most frequently discussed involved Maria the Robot having disguised herself as a mortal, writing a book about Mabuse, and Fritz Lang making it into a movie, only to be haunted by Mabuse who would then take over Hitler's position in Germany. Another suggested idea was a story taking place in an Orwellian dystopia of the future - hence AD 1984. No other details other than setting were developed.
