Revealing mistake: There is a spring in the skull in the scene where Clark is roaming through the desert and falls down by the skeleton with the gas can.
Continuity mistake: In St. Louis, after the guy asks for five dollars, Ellen says, "That's a fair deal." She turns her head to the right and smiles. The shot cuts to an outside look at the front of the car. Ellen isn't smiling anymore.
Revealing mistake: When they are riding the rides at the end, someone has to be starting and stopping them.
Visible crew/equipment: When Aunt Edna tells Eddie "see I told you he wouldn't like them", Clark closes the door in her face. A film light is reflected in the center of the frame.
Other mistake: When Clark and the gang force the security guard onto the "screaming meemy" roller coaster, it starts to roll with no-one operating the controls.
Suggested correction: Every ride they ride would be a mistake as there was nobody to operate any of them.
Revealing mistake: Aunt Edna is supposed to be dead, but look closely as she's sitting in the pool chair, and you can see her upper body move slightly.
Revealing mistake: Christie Brinkley supposedly jumps in the pool naked but she's wearing a flesh colored top that can be seen in several shots.
Other mistake: In the first gas station scene, Ellen directs Clark to the gas tank opening which Clark has thus far been unable to locate. Despite being a brand-new car, the inside of the gas tank lid is completely rusted.
Factual error: The whole movie he drives without any valid license plate. Just a crooked colored plate from the auto store. He would have been pulled over for that immediately, and the car probably would be impounded. Then when he does get pulled over for the leash, the cop says nothing about invalid plates. But he asks for registration proof and Clark shows it, even though he has no legal plates. Plus his meaningless plate is crooked, which is also illegal.
Suggested correction: The first 30 days after you purchase a new car you don't need plates.
Any place I've lived has required at least temporary plates before the car is actually registered.
The officer still would have to run the VIN numbers to make sure the car isn't stolen. A long time ago certain states wouldn't give you a temporary plate at all, you would only have the dealership plate on the back of the car which would raise any suspicion of law enforcement if they were to get behind you, but no ticket would be issued as long as the car is within 30 days and not stolen.
