If you like early-70s Hammeresque Horror, pick this one up -- it's worth it to watch Christopher Lee and Peter Cushing face off. Also for this exchange:
Christopher Lee: "I've got to get hold of that skeleton somehow."
Doctor Perry: "Oh I don't know... There is the question of professional ethics."
Christopher Lee: "Oh indeed, indeed... that is why I shall have to employ someone for whom ethics have no significance."
