Director
Ulli Lommel was unsure about casting
Klaus Kinski, but he met him and Kinski was very nice, according to Lommel. But when the filming started, Kinski was very hard to work with. He complained about the lights and microphones, so eventually they had only few soft lights and very small microphones in the Kinski scenes, which is the reason why the sound quality changes much in different shots. Kinski also didn't want to sit on a chair when camera crew was about to shoot from different angle, so continuity wasn't possible. Because of that Lommel decided to change Kinski's character to a ghost, which was a brilliant idea in Kinski's opinion. Later he was so happy with the director that he said he doesn't work in the future with anyone else than Lommel, but Lommel's answer was simply "Yeah, right".
