Today Dracula is one of the most ubiquitous public domain characters in popular media. However, in the 1920s German filmmakers had to get permission from Bram Stoker’s estate in order to make a film based on the 1897 novel. Prana Films, however, was not able to secure permission from Stoker’s widow for an official adaptation. Instead, producer Albin Grau and director F.W. Murnau made Nosferatu, a Dracula film in all but name.
