Between 1966 and 1967 Roman Polanski, until then known for his cruel narrative, grotesque and surreal vein in films like “Repulsion” and “Cul de sac”, made the first, and until now best, parody of the popular vampire genre that in the years of silent film produced two real masterpieces: “Nosferatu” (1922) by F.W. Murnau and “Vampyr” (1932) by C.T. Dreyer. The original title of this exhilarating feature film is “The Fearless Vampire Killers”; in Italy it became the malicious “Per favore non mordermi sul collo” and in Germany “Tanz der Vampire”. A part of the work was made in Val Gardena. The arrival of the rowdy film company upset the lives of some people for several weeks, not only those involved as extras and drivers, but also the managers and waiters of the hotels in which the filmmakers stayed. The film cast’s lack of moderation, their behaviour so different from that of the local people, both during the shooting and in pauses, the overwhelming beauty of the actress Sharon Tate (Polanski’s wife at the time) have remained vivid in the memory of the valley dwellers. The documentary recalls that time and glimpses behind the scenes, giving voice to the witnesses of what was, for then, an epic and unique event.
