The Head of Janus
The Head of Janus is a 1920 German horror silent film directed by F. W. Murnau. It was also reviewed at the time under the title Schrecken (Terror). The film was an unauthorized adaptation of Robert Louis Stevenson's 1886 novella The Strange Case of Dr. Jekyll and Mr. Hyde, but the source material went unrecognized by some of the German media due to changes in the characters' names. For example, the Jekyll-Hyde character was called Dr. Warren and Mr. O'Connor in the script. But that isn’t all the film is known for. It also features an early film role for future-Count Dracula Bela Lugosi as a variation of Poole, Dr. Jekyll’s butler in the book. Marnau would later make an unauthorized adaptation of the Bram Stoker novel two years later with Nosferatu: A Symphony of Horror.
