Nosferatu, eine Symphonie des Grauens (translated as Nosferatu: A Symphony of Horror; or simply Nosferatu) is a classic 1922 German Expressionist horror film, directed by F. W. Murnau, starring Max Schreck as the vampire Count Orlok. The film, shot in 1921 and released in 1922, was an unauthorized adaptation of Bram Stoker’s Dracula, with names and other details changed because the studio could not obtain the rights to the novel (for instance, “vampire” became “Nosferatu” and “Count Dracula” became “Count Orlok”).
   Nosferatu was the first and only production of Prana Film, founded in 1921 by Enrico Dieckmann and Albin Grau. Grau had the idea to shoot a vampire film; the inspiration arose from Grau’s war experience: in the winter of 1916, a Serbian farmer told him that his father was a vampire and one of the Undead. Diekmann and Grau gave Henrik Galeen the task to write a screenplay inspired from Bram Stoker’s 1897 novel Dracula, despite Prana Film not having obtained the film rights. Galeen was an experienced specialist in Dark romanticism; he had already worked on Der Student von Prag (The Student of Prague) in 1913, and the screenplay for Der Golem, wie er in die Welt kam (The Golem: How He Came into the World) (1920). Galeen set the story in a fictional north German harbour town named Wisborg and changed the character names. He added the idea of the vampire bringing the plague to Wisborg via rats on the ship. He left out the Van Helsing vampire hunter character. Galeen’s Expressionist style screenplay was poetically rhythmic, without being so dismembered as other books influenced by literary Expressionism, such as those by Carl Mayer. Lotte Eisner described Galeen’s screenplay as “voll Poesie, voll Rhythmus” (“full of poetry, full of rhythm”).
   The story of Nosferatu is similar to that of Dracula and retains the core characters—Jonathan and Mina Harker, the Count, etc.—but omits many of the secondary players, such as Arthur and Quincey, and changes all of the characters’ names (although in some recent releases of this film, which is now in the public domain in the United States but not in most European countries, the written dialog screens have been changed to use the Dracula versions of the names). The setting has been transferred from Britain in the 1890s to Germany in 1838.
