The film was originally envisioned to be a disaster-themed film, but as the production developed director Jean Rollin saw the potential for it to be a horror film instead.
Writer Jean-Pierre Bouyxou appears in the film as the mad villager wielding the scythe.
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.
According to director Jean Rollin while shooting the nude scene with actress Brigitte Lahaie the outside temperature was so cold that Lahaie couldn't speak her lines.
Writer Jean-Pierre Bouyxou appears also in the film as the one-eyed living dead.
