Nosferatu the Vampyre

Nosferatu the Vampyre is a 1979 West German "re-imagining" of Nosferatu: A Symphony

 of Horror, written and directed by Werner Herzog. Its original German title is Nosferatu: Phantom der Nacht ("Nosferatu: Phantom of the Night"). The film is set in 19th-century Wismar, Germany and Transylvania, and it stars Klaus Kinski as Count Dracula, Isabelle Adjani as Lucy Harker (Mina in the book), Bruno Ganz as Jonathan Harker, and French artist-writer Roland Topor as Renfield. Mina ´s friend Lucy  (Martje Gortman in small role ) was now called Mina.

There is also novelization Nosferatu the Vampyre by Paul Monette.

Animal cruelty
In 2010, Dutch behavioral biologist Maarten 't Hart, hired by Herzog for his expertise of laboratory rats, revealed in the TV program Zomergasten, that after witnessing the way in which the rats were treated, he no longer wished to cooperate. Apart from travelling conditions that were so poor that the rats, imported from Hungary, had started to eat each other upon arrival in the Netherlands, Herzog insisted the plain white rats be dyed gray. In order to do so, according to 't Hart, the cages containing the rats needed to be submerged in boiling water for several seconds, causing another half of them to die. The surviving rats proceeded to lick themselves clean of the dye immediately, as Hart had predicted they would. Hart also implies sheep and horses that appear in the movie were treated very poorly, but does not specify this any further. In the TV program, he called Herzog´s behavior  "immoral".
