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)
Revealing mistake: Cruise and Lugnut are driving home along a road after speaking with Mr. V8 and Coupe about the race. For the entire four minutes of this scene, the shadow of Cruise's wing mirror cast on the road passes under the road markings, when it should be cast on top of the markings. (00:04:00)
