The cuckolded husband (Paul Muller) is determined to torture and kill his wife (Barbara Steele) and her lover (Rik Battaglia). He cuts out their hearts and goes on enjoying her money.Dr. Arrowsmith (Muller), much to the surprise of his housekeeper Solange (Helga Liné), marries his wife's twin Jenny (also played by Barbara Steele).Writer/director Mario Caiano, who also gave us the gem Nazi Love Camp 27, manages to tell a compelling story. It all seems simple enough for the doctor, but he didn't count on the supernatural.Good flick for the time.

"Nightmare Castle" (1965) is a mildly enjoyable horror film starring the ever-creepy Barbara Steele. Steele is murdered by her evil-scientist husband for her adulterous ways. He then uses her blood to rejuvenate his aged girlfriend. Then he marries Steele's blond sister (also played by Steele) and attempts to drive her insane so he can send her to a loony bin and spend her large inheritance. But Steele's ghost is trying to possess her sister for revenge. The evil husband sends for a psychiatrist--who just happens to be a good lookin' hunk o' man--and he begins to fall for blondie. He suspects foul play. (Does this seem at all convoluted?)

Italian queen of Gothic horror Barbara Steele portrays the wife of a deranged scientist played by Paul Muller whose latest experiments involve electro-stimulation of human blood.When the mad doctor discovers that his wife is unfaithful,he tortures,disfigures and kills her alongside her gardener lover,then removes and preserves the hearts of the victims,using their blood to restore youth and beauty to his own lover Solange.When the madman discovers that his late wife left all her wealth to her mentally unstable sister he quickly sets about courting and marrying the poor girl,then proceeds to drive her completely mad in order to inherit her fortune."Nightmare Castle" is an essence of Italian Gothic horror.It takes place almost entirely in castle interiors,frequently in utter darkness.There are some scenes of depressing violence and the visuals are rich and beautiful.The hypnotic eyes of Barbara Steele are not easy to forget.9 out of 10.

When a twisted count finds his wife cheating on him with the gardener, he tortures and kills them both, then removes their hearts. Years pass and he remarries his wife's stepsister who is thought to be crazy but was left lots of money from her now dead sister. Soon she is experiencing horrible dreams and seeing ghosts. A doctor comes to see her to see if she's insane. You see, if she is found insane, the count will be in charge of all her money so he does his best to keep her disturbed, although these ghosts are really those of the counts slain wife and horny gardener. See where this is going? To be honest, it's not a bad movie. The acting is not bad, although the script is a bit weak at times. Barbara Steele plays the wife and stepsister and this movie is pretty much owned by her good performance. It's not all that scary but fairly well shot and has some good ideas but I just don't think it's made creatively enough to make it stand out among lots of other bloody revenge flicks. Not great but makes a fairly decent late night viewing.
