According to director Jean Rollin while shooting the nude scene with Brigitte Lahaie the outside temperature was so cold that Lahaie couldn't speak her lines.
The filming locations had extremely cold temperatures and often the makeup effects would start to freeze on the actors, making it difficult for them appear realistic on camera.
Writer Jean-Pierre Bouyxou appears in two different bits : as the one-eyed living dead (with mustache), and as the living dead with a scythe (without mustache).
Porn actress Brigitte Lahaie has worked with Jean Rollin in the porn film Sensual Vibrations, in Les Raisins de la Mort (Grapes of Death) and Fascination. He first decided to use her in his mainstream films because he felt she had a "strange presence," which fit perfectly with the tone of his horror films. Rollin had a particular fascination with Lahai and admitted in interviews that he considered her "the perfect example of womanhood."
The first gore film produced in France.
