Continuity mistake: In the opening credits when the title comes up, there is a picture of Mater beside it with the Ghostlight after him. Mater has his right headlight still intact. But during the film, he loses his remaining right headlight moments before he is scared by the lightning bug, before the Ghostlight ever gets to him. (00:00:10 - 00:04:10)
Continuity mistake: When Wrangler drives over the nails on the road, he comes to an abrupt stop. When he stops, the tyres are still positioned in the same place, but in the next shot, the tyres are suddenly dislodged and sticking out of the car, as a way of representing he has broken down. (00:30:25)
Continuity mistake: Hargon has a hook for a left hand. After the opening credits (during the dice roll scene) the hook is briefly on his right arm. Then it's left again during the rest of the episode.
