The Bloody Pit of Horror.
After watching one ropey Italian horror film Prime decided that I might like this as well.
Centuries ago the sadistic Crimson Executioner is put to death and entombed in a castle, now the current owner believes that he is the executioner reincarnated.
Conveniently a book publisher turns up with a photographer and models looking for a location, and you can probably guess the rest.
Grisly deaths, hilariously over the top camp acting from the baddie, and a fight scene so laughable that my grannie could've battered the pair of them.
Apparently the BBFC refused this a certificate in 1967, probably for the S+M overtures that wouldn't bat an eyelid today.
Definitely one for the, so bad it's good category., 5/10.
