For director Robert Wiene, he yearned to duplicate his success by hiring "Caligari's" writer, set designer & cinematographer for his next project, September 1920's "Genuine: The Tale of a Vampire." Using the same framing structure, the tale has a former painter falling asleep while reading a horror novel. His dream is about his portrait of a high priestess, Genuine, hanging on his wall above him. The dreamlike quality of the movie is similar to "Caligari" with its surreal sets and tone.
The term vampire in those days in cinema meant a woman taking the financial pants off of unsuspecting men. Such was the femme fatale Genuine, the subject of Wiene's film. Unfortunately for the director and Decia Studios, "Genuine" was a colossal flop. But that didn't stop him from directing well into the 1930's, producing some classics along the way.
