If you're a fan of Gothic horror, then you're definitely absolutely guaranteed to LOVE this wondrous Italian 60's film "Castle of Blood". We're really talking about creepily creaking doors, eerie portraits that appear to be moving, spontaneously dying candles although there's no wind and smoke coming from underneath heavy wooden chamber doors. Speaking in terms of atmosphere and style, this masterful piece of Gothic film-making is one of the best out there; just one tiny league below landmarks such as "Black Sunday", "The Three Faces of Fear" and "Curse of the Crying Woman". The prominent directors duo Sergio Corbucci ("The Great Silence", "Django") and Antonio Margheriti ("Cannibal Apocalypse", "Killer Fish") are successful in all areas, including a powerful plot (one that is genuinely nightmare inducing), ultra-sinister scenery and filming locations, stylish black and white photography, spine-chilling music and a brilliant gathering of talented performers. Barbara Steele, starlet of the aforementioned "Black Sunday" and Italian goth-muse number one, shines brightly again as a spiritually tormented character and she's literally surrounded by excellent co-players. One of them, Silvano Tranquilli, even gives away a fairly credential depiction of author Edgar Allan Poe. The story involves him and another wealthy visitor of a countryside tavern challenging a brutal young journalist to accept a morbid wager. If he  Alan Foster  would survive spending one night in the infamous Blackwood Castle, he receives the astonishing reward of $10 and a newspaper interview with Poe. Needless to say the ordeal is much more dangerous than it sounds, even for somebody like Alan Foster who's a firm non-believer in ghosts and vampires. The night starts out great for him, as he even meets up with the stunningly beautiful woman of his dreams, but gradually he learns that Blackwood Castle is a hellish place where the ghosts of the previously deceased visitors are trapped for all eternity. I don't know about you, but this is seriously one of my favorite horror movie premises of all time. Co-director Antonio Margheriti clearly was proud of this film as well, because he remade it himself a couple of years later as "Web of the Spider". That movie had a handful of trumps, like for example the casting of no less than Klaus Kinski in the role of Edgar Allan Poe, but in general this original is vastly superior. "Castle of Blood" literally oozes with atmosphere and maintains a thoroughly unsettling ambiance throughout. This truly is one of the rare films that can make the hair on your arms and back of the neck rise with fear if you watch it in the right circumstances. Watch it late at night, preferably alone and in a candle lit room, and you'll get an idea about the true definition of horror.
