Continuity mistake: The lit flashlight dropped on the floor by the soon-to-be beheaded victim disappears in subsequent shots.
Revealing mistake: The headless motorcycle rider's torso and arms are not in proportion to a real motorbike rider. The torso is obviously made larger to accommodate the stunt bike rider.
Revealing mistake: The pre-cut hole in the garage door is visible before and after the motorcycle busts through it.
Continuity mistake: When the headless biker attempts to run over Studs Spake, the biker crosses in front of the prone Spake. The instant shot then shows the biker crossing again, but this time behind Spake.
Continuity mistake: When Lila is packing her clothes, she has a black garment in her hands, but the next quick shot shows her hands empty.
Visible crew/equipment: When Kolchak goes to visit Mr. Cahill in the mental hospital, the boom mike's shadow is visible in several shots.
Factual error: Kolchak's narration has the episode's events begin in February in Chicago, but there is no snow, nor indication of cold weather.
