Continuity mistake: In the scene just after Joe finds his parents, when they are sitting in their trailer talking, his parents have a stuffed clown between them. Just before Joe asks them if there ever was a time when they'd be staring at the moon, the clown is slumped forward with its face not visible. In the next shot, when his mom starts her sales pitch about having clowns for sale, the clown is now standing upright between them.
Continuity mistake: When Joe spins the tires for the security guy, The tire that's supposed to be spinning is on the left side. But after Joe says "does this look like a piece of crap to you?" It shows the right side spinning on close up 3 times, But when they show a wide shot of the car the right side is not spinning at all and the rubber burns are on the left side of the car. (00:01:45)
Revealing mistake: When Joe is strapped to the atom bomb he orders a girl to show him her boobies. When she takes her top off, you see a back shot of her (so you can't see her boobs) but her body is transparent and you can see Joe's arm through her body. Obviously, the girl was superimposed onto the shot. (00:34:40)
Continuity mistake: At the end of the movie when Joe, Brandi, Kickin' Wing, Gert B. Frobe, and the alligator girl are in his car, Robbie pulls up along side of them. Joe pulls out, spinning dirt and rocks toward Robbie's car, and a camera shot from inside his car shows Joe's car speeding away, and the windshield is completely clear. But in the very next shot, from in front of Robbie's car, the windshield is broken, and has 2 places where it appears as if large rocks had hit, but they weren't there seconds before, and the dust and flying rocks had already begun to clear by that time. It is illogical for a rock large enough to do that kind of damage to his windshield to have suddenly kicked up, judging from the distance it shows Joe's car away from Robbie's in the previous shot.
Continuity mistake: Near the end of the movie Joe wakes up at Brandi's house and they run out to find Joe's "hemi" sitting in front of the house. The camera shot shows the car from the right side, and you can see the rear-view mirror attached to the windshield. And shortly afterward when they all get in Joe's car, another camera angle shows the mirror as well. But when they're speeding away from the house the camera angle from the front of the car shows the mirror is no longer there.Hawk
