Continuity mistake: In the scene when Jack Black is about to be unmasked and the kids are watching his match on TV, Chancho goes to to cover the TV. He is wearing a pink shirt but in the shot of him covering the TV he is wearing a white singlet.
Other mistake: The monitor from inside Mack's trailer displays his whole face while talking to McQueen. There is no camera outside of Mack that can display him in that fashion.
Suggested correction: The camera in the trailer may be a TV video instead of a camera.
No, McQueen is talking live with Mack through this monitor.
Continuity mistake: In the scene where Haley is sitting in the bathtub full of ice, she is wearing a black sports bra. The shot then switches to some of the girls watching a news report from the Worlds competition. It then switches back to Haley, who is now wearing a gray sports bra.
