Continuity mistake: When the two brothers are frantically trying to get out of the car because the monster truck is barreling toward them (in slo-mo), you will notice that the tongue ring is missing from the one brother's tongue. Odd mistake seeing as his character is centered around the tongue ring. (01:27:05)
Continuity mistake: When Tracy visits her boyfriend in the helicopter, she starts to throw random objects at his truck. Watch her first throw where she cracks the back window, you'll notice that the front bonnet is dented although nothing has hit the bonnet yet. If you believe something might have been thrown before that, when she throws the second and third object there is no dent where that one was. (00:46:25)
Continuity mistake: When Tracy is throwing things at her boyfriend's truck, you can see two dents in the roof. However, when Tracy is chasing her boyfriend, there is no damage to the roof.
Continuity mistake: When all the characters get to Silver City and get to the locker room, we see Seth Green in the background and the dude with the tongue ring in front leaning on the door frame. The next shots shows Seth in the front and the tongue guy behind him saying he's sleeping. How did Seth get there so fast? (01:32:45)
Continuity mistake: In the Balloon Chase scene, if you watch the sky it changes a couple of times. One time it's overcast, the next it is evening and the sky is orange. (01:02:25)
