Taste the Blood of Dracula (1970)

Secker has a book on vampires in his library, and copies out the relevant information for Paul Paxton to go to destroy Dracula. His girlfriend Linda has been rejected by Dracula, and so her hypnotic dedication to the vampire is put under strain by Paul's insistence that she is "free to choose, Good or Evil". Made infuriate by Paul Paxton's attempt to sanctify his abode and despatch him, Dracula scales the interior of the desecrated chapel, throws organ pipes at the couple; and all the stained glass panels are suddenly flooded with religious light, colour and symbolism. Overcome by the forces of Good, Dracula falls, crashes on to the newly blessed altar, and begins decaying into the powder and bone from which he was initally reconstituted. Alice is free; and the young couple rush together from the chapel, and away.
