Continuity mistake: When Cuba Gooding Jr.'s character is being chased by the Lucy look-a-likes his jacket is sweaty and dirty. Then when he wakes up in front of the horse pasture it's perfectly clean and bright white, like it just got washed and bleached. (01:23:00 - 01:23:55)
Continuity mistake: At the monster truck ralley, in the first shot as the monster truck revs up, ready to jump the ramp, look at the huge advert signs behind it. One of them has "PowerBar" written on it, but in the second shot as the truck roars over the ramp, the same sign is now totally different. (01:23:25)
Continuity mistake: When most of the gang has arrived at Silver City, Owen jumps off of the horse he is riding, and then it cuts to a shot of Randy, who leans out of the lorry window to see what's going on. When it cuts back to Owen, Randy is suddenly sitting back normally in his seat. (01:26:45)
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: As everyone is grabbing money from the duffel bag, just before all the lights turn on at the "Feed the World" concert, Merrill is getting money from the bag in one shot, but in the next shot, as the lights turn on, she is now nowhere near the bag, and with money in both hands. (01:32:40)
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: At the end when everyone is dancing with Smash Mouth, just before Randy plays the harmonica Vera is singing with the singer of Smash Mouth, then in the next shot she is dancing behind Randy as he plays, and then in the next shot she is back dancing with the lead singer. (01:40:10)
Continuity mistake: When Merril and Vera ask the squirrel lady for directions, she tells them to drive 1.8 miles to the Totem Pole ranch, and to then go 5.4 miles until they get to a yellow sign with graffiti on it. However when they get to the yellow sign with graffiti on it, Merrill says "OK, we're at 2.4 miles" - it should be 5.4 miles.
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: Tracey's hair in the helicopter jumps from under the headset to falling around her face and back again.
