Nosferatu the Vampyre is a 1979 gothic horror film written and directed by Werner Herzog. It is set primarily in 19th-century Wismar, Germany and Transylvania, and was conceived as a stylistic remake of F. W. Murnau's 1922 German Dracula adaptation Nosferatu. The picture stars Klaus Kinski as Count Dracula, Isabelle Adjani as Lucy Harker, Bruno Ganz as Jonathan Harker, and French artist-writer Roland Topor as Renfield. There are two different versions of the film, one in which the actors speak English, and one in which they speak German.

R. M. Renfield is a fictional character who appears in Bram Stoker's 1897 Gothic horror novel Dracula. He is Count Dracula's deranged, fanatically devoted servant and familiar, helping him in his plan to turn Mina Harker into a vampire in return for a continuous supply of insects to consume and the promise of immortality. Throughout the novel, he resides in an asylum, where he is treated by Dr. John Seward.
