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.

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)
Factual error: The bullet that was fired and travels next to the rocket car defies the laws of physics. Assuming that the bullet was fired parallel to the ground, the bullet should remain in the air for the same length of time as it would take to drop the bullet from the same height. The bullet in this scene remained in the air for a much longer period of time.
Factual error: As Whoopi Goldberg and her daughter stop the rocket car, the engines on it are clean and shining. After driving through all the brush, not only would they have been very dirty and filled with plants, they would probably have been FODed (Foreign Object Damage) out and quit running long before it ran out of fuel.Jason Sieberg
Revealing mistake: When Vera and Merill are talking to the squirrel lady, whenever you can see the ground behind the squirrel lady, near one of the cages, you can see a squirrel that is obviously fake. It is not moving at all and looks like it is carved from wood.
