It's sad that "The Incredible Doktor Markesan" ended so badly, as up until then it had been incredibly creepy and gripping. Up until the end, I was anticipating giving this one a 9, but the ending was just awful.
Fred Bancroft (Dick York) and his wife are broke with no place to go. Out of desperation, they head to Uncle Konrad's house--and uncle that Fred hasn't seen in many years. However, when they arrive, no one seems home and the place looks decrepit and filled with cobwebs. Soon, the uncle arrives (Boris Karloff) and he looks rather cadaverous. He also talks very little and seems a bit zombie-like. However, he does agree to let them stay on one condition--that they NEVER leave their room at night. And, to insure this, he locks them in their room. Naturally, Fred is dying of curiosity and one night he goes for a peek... What he sees, you'll have to see for yourself. Suffice to say that it's really creepy and cool. But, at the very end there is a miraculous ending that seemed cheesy and stupid--sort of like in Dr. No where there was a self- destruct lever just waiting to be pulled!! It's a shame, as up until then it was exceptional.
