this is hilarious .. spoiler

check out a review on amazon:

If you ever wanted to see a film where a dead ancestor resurrects with the sole purpose of helping the protagonists with shoveling work, then look no further. Also, if you're a fan of hunchbacks with comedically oversized hunches, find this film. Aaaand also if you just fancy spooky nights with some atmospheric castle horror, you owe yourself to have a look at Terror in the Crypt.

In the film Christopher Lee wants to satisfy his curiosity of a certain matter, and hires a guy to do so. Things get tricky when a carriage dumps a mysterious young woman at his castle (supposedly just until they get repair work done, but we never see the carriage again so I think they just wanted to abandon her) and starts to hang out with Lee's daughter. What follows is vampirism with lesbian undertones, quite sensual but of course not Jesus Franco levels of sleaze, this being '64.
