 Among the cast was Jane Birkin, at the time still mainly known for the popular song "Je t'aime... moi non plus" which she had recorded with her lover Serge Gainsbourg.Margheriti also cast Gainsbourg in a bit part, and later stated that Gainsbourg had asked, while visiting Birkin on set, to play a cameo in the film.The film's score by Riz Ortolani uses cues from previous Margheriti films such as "The Virgin of Nuremberg", "Castle of Blood" and "Seven Deaths".
