 Director Wiene created "Genuine" as a follow-up to his massively successful 1919 film "The Cabinet of Dr. Caligari", using the same writer and cinematographer who had worked on the earlier film.Production designer Cesar Klein even returned to contribute his bizarre Caligari-like imagery to the film.Genuine is not actually a vampire in the film, but rather a vamp (succubus) who uses her powers of seduction to torment and control the men who love her.
