After securing Kinski for the lead of Nosferatu, producer August Caminito planned a sequel to Werner Herzog's "Nosferatu the Vampyre". Caminito originally secured Maurizio Lucidi as the director but later felt that film would be better with a more well known director and a higher budget, leading Lucidi to be dropped as the director in favor of Pasquale Squitieri. Squiteri made several changes to the script which did not appeal to Caminito, which led to him paying Squiteri and terminating his contract. This led to further budget cuts in the film and hiring Mario Caiano on as the director. After clashing with Kinski on set, Caiano left the film leading Caminito to direct the film himself. During filming, Kinski would not follow rehearsal and demanded changes in the actors appearing in the film and often had lighting changed dramatically on set. According to second unit director Luigi Cozzi, Kinski's behaviour on set became so erratic that the entire crew left the set and did not return until Kinski apologized for his behaviour.
