Fred and Molly Bancroft, a pair of penniless newlyweds, are so desperate that they visit Fred's mysterious uncle Konrad Markesan, whom he hasn't seen in over twenty years. They are hoping to live in with him rent free until they can find jobs and be self-sufficient. The once-beautiful mansion is in a decrepitly musty state, filled with dust, cobwebs, and rats while Fred's once-kindly uncle is now a disheveled, cadaver-like figure who offers them shelter on condition that they never leave their room after dark, a condition that Markesan insures by locking them in at night.

The twilight of his illustrious career saw Boris Karloff come full circle, as THRILLER was filmed at his longtime home studio Universal; the house seen in this entry is the same one where Lon Chaney's Kharis perished in the fiery finale of 1942's THE MUMMY'S TOMB. See more »

Boris Karloff: Above all, do not seek me out or disturb me for any reason whatever.
Fred Bancroft: Whatever you say, sir.
Boris Karloff: [Pausing by the door before he leaves] One more condition, and this is vital - I don't care to have you venture forth at night. You must either stay in these rooms from dusk until dawn or leave the house entirely for the night. You understand?

It's zombie time!
8 April 2014 | by See all my reviews

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.
