Revealing mistake: The same clip of Curly getting hit on the top of the head with a lump of clay is shown twice during the clay fight.
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)Quantom X

Revealing mistake: When Cruise and Lugnut are driving home after talking with Mr. V8 and Coupe, much of the scene is a shot of the two of them talking with each other and occasionally in the scene, the shot will cut to a closer angle of the two, with the shot focusing on either Cruise or Lugnut. Whenever the shot is on the closer angle, the resolution of the animation becomes blurrier. This could be because the closer angles are merely the same shot of the two, just zoomed in more, which would cause the resolution to decrease. (00:04:25)Casual Person

Revealing mistake: When the Level 3 Sentry is firing up into the air for no apparent reason, it fires some rockets with a clear defined smoke trail behind them and disappear off screen. Then the shot jump cuts to further away and suddenly the smoke appears again, but the end of the smoke trails are solid and crisp indicating the animators used the smoke animation as if the rockets had just been fired from that spot... in the middle of the sky.
