Among the many versions of "vampire" movies, this one directed by John Badham is less well-known, but the leading actor Frank Langella successfully created the image of a gentleman vampire with noble temperament. It tells the story of the bloodthirsty Count Dracula who left his castle and ran to the modern London city to pursue new prey, thus experiencing many interesting encounters. In terms of the performance of the director, this film is only average, but the veteran actors Laurence Olivier and Donald Pleasence are both worth watching.
