Nosferatu
Similarly, the short film 'La duodécima hora'  by Rodrigo Plaza and film critic Juanma Ruiz, suggested a hidden plot orchestrated by Nosferatu director and producer, F. W. Murnau and Albin Grau, to hide an elixir of the eternal life. Shot as a mockumentary, the film starred horror icon Paul Naschy and Nosferatu film restorer Luciano Berriatúa.
