Creatures who suck the blood of the living

The flamboyant Count comes to England because he has purchased a derelict old castle. And he lusts for fresh and delicious British blood of course. To be honest, I didn't know the existence of this Dracula movie even though there are lots of heavyweights in the cast; Frank Langella as Count Dracula, Laurence Olivier as professor Abraham Van Helsing and Donald Pleasance as Dr. Jack Seward. Directed by John Badham in 1979. Not particularly outstanding adaptation of Bram Stoker's novel, but a visually atmospheric little horror tale.
