Revealing mistake: Right after McQueen asks what the Ghostlight is, it cuts back to the other cars. Luigi is right next to the firetruck and some gas pumps. The firetruck's door is very reflective, and the gas pumps are visible in it. But Luigi is right by the pump, and he is not reflected in the firetruck's door. (00:02:10)
Audio problem: When Wrangler goes to sabotage the Champ's fuel supply, he approaches the gasoline tank saying, "Once the Champ knocks back a quart of this go juice, I think he'll find his get up and go, is all gone." Wrangler can be seen in the shot when he says, "Once the Champ", but his lips do not move. (00:20:10)
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.
