As others have mentioned, a group of photographers and models working in an Italian castle fall prey to a reclusive actor who thinks he is the reincarnation of the Crimson Executioner, a 17th century sadist and murderer who was executed and entombed in the castle. The idea for the plot isn't bad, but the former muscle man they hired to play the killer overplays his role so much it's laughable; all you hear him talk about is how perfect his body is and how impure the models and crew are - his gives a performance that is a textbook example of unintentional hilarity! Later scenes deal with the torture and humiliation of the models in the dungeon of the castle; these scenes are rather disturbing to watch even though everything is obviously faked. Not a great film but not bad either; has some good footage of a historic Italian castle in the countryside, and features some attractive young actresses as the models.
