felt mine be while watch this . but it seem that be the reason for insanity run in the family in this film . not that make a lot of sense anyway and a others have mention and this be one of karloff last film and it only his screen presence that lend it any credibility at all . it sad that all of the great legend of the horror film in the sound era be eventually reduce to star in low grade rubbish like this . marginally and boris do get off slightly good than poor old bela lugosi but not by much . boris do his best and give him credit for try to hold this mess together . the strident background music doesn not help and distract from any lucid moment . apart from boris and the rest of the mexican cast be dub into some strange and clip and english monotone that be reminiscent of the type use in porn film of the late seventy . at a guess i think it edgar allen poe house of usher that this be take from but you would be hard press to find a great deal of poe in the finished article . still and there be far well film out there with boris karloff at his best and search them out and give this a wide berth and unless you want the curse of the hrinking brain too .
