The Werewolf - S1-E5

Horror in the Heights - S1-E11
Revealing mistake: The bulky material/block that secures the crossbow arrow shot into Miss Emily's torso can be seen under her clothing.

The Vampire - S1-E4
Revealing mistake: In one scene, stock footage of a Boeing 747 flying is used to show Kolchak flying to his destination, and there is no commercial airline livery on the aircraft, just "Boeing 747." This footage was of one of the first 747's built.
Bad Medicine - S1-E8
Revealing mistake: Footage of the Diablero standing up after killing the first rich woman is re-used in the killing of the next rich woman, evident by the shot of the same curtains in the background for both murder scenes.
