According to his autobiography, in 1983 Klaus Kinski told producer Peer J. Oppenheimer that he would agree to star in this film, as long as he arranged for him a night of sex in Munich with an actress (clearly Constanze Engelbrecht) who at the time was shooting in Budapest a film (Viadukt (1983)) produced by Oppenheimer himself. "I don't know her and I've never seen any of her movies. I don't even realize that she's Germany's biggest female movie star. All I know is that I got a boner when I saw a photo of her face in a newspaper. I tell the guy that I'll do his fucking movie if I can fuck the star. He's to phone her. This instant. Now. She's to hop a plane today and come. For one night. She comes. The three of us have dinner at the Hilton. Then we send the guy away and she comes to my room. She has the longest vaginal lips I've ever licked and stuck my horny cock into. Then I ram into her from behind. Her face is on its side on the mattress so that I can see her swollen mouth, which shamelessly twists in dreadful passion. After I shoot my second load in her, she has to fly back."- Kinski wrote.
