Revealing mistake: When the king's youngest daughter mounts the Polar Bear King the lack of effort reveals that she does this with the help of a cunningly placed stepladder. (00:25:35)
Revealing mistake: When Dolph is shot, Brandon says, "It went straight through," meaning that the bullet went straight through Dolph's body. However when it cuts back to Dolph later you can see the bullet has entered the heart region. In other words the heart would most likely be damaged and Dolph would have been dead. (01:09:20)
Revealing mistake: When Rollie is hanging from the ladder and the bolt breaks, you can see the smoke from the exploding bolt. (00:42:50)

Revealing mistake: Junior can't get on the Crazy Dance because he is a milimeter too short. After seeing Murph (the 20-year old in his class) and Trixie (on heels) get on it, Junior speeds up the ride and all the kids on it get dizzy and barf everywhere. If you look where the puke shoots out, it's a bit obvious it's not coming from their mouths, but from a point behind them. Most obvious are Trixie and the boy wearing glasses.
Revealing mistake: Close to the end of the film when Joe is in the woods with all the bad guys, he starts to shoot them, as he shoots the first bad guy, if you pause it before he shoots, you can see that there is a rather large lump in the guys forehead where he gets shot, obviously some kind of squib or something to make the effect of being shot in the head. (01:13:30)
Revealing mistake: When the plane is delayed because the luggage got crushed, the sign changes their flight status to DELAYED. It's obvious that the one that changed is the only row meant to move. The letters are spaced out so that they can flip over but all the other letters have no spaces and actually look like stickers.
Revealing mistake: When the crack house has been shut down and they're having a meeting to find out what went wrong, Wesley Snipes stabs one of the crew in the hand with a small sword. But the next shot (just for a split second) shows the sword in the table with his hand next to it, not stabbed. A couple of cuts later the sword has been pulled from the table and the apparent victim is in considerable pain. (00:56:00 - 00:57:00)
Revealing mistake: When the killer is putting masks on in front of Maggie, you can see the dead body of Tina hanging behind Maggie. The dead body moves / shakes / breathes many times throughout the scene.
Revealing mistake: About half an hour into the movie, when Frank is in the tank, he plows into a supposedly concrete zoo wall, which wobbles. Also, the wall splinters where it meets the sidewalk, revealing that the "wall" is actually a wood prop, and a flimsy one at that. Five seconds later, when people and animals are shown running out, the same wall is shown with a different shaped hole and pieces of concrete lying around it. Apparently the concrete pieces aren't too real either, as the camel kicks one around as easy as if it were made of foam. (00:30:25)
Revealing mistake: When Henry is out on the balcony and Sara comes out carrying a bottle of beer, Henry is leaning with his elbows resting on a ledge. It can be seen that there is some kind of pad or cushion on there because you can see it give when he moves. When they sit the beer bottle down on there the sound effects of one touching stone or concrete can be heard. That should not be heard if the bottle touches the pad or cushion that is on there.
Revealing mistake: The scene which introduces Sue Ellen working on her new job at Clown Dog firstly depicts people walking in and out of the shop, while the staff serve at the counter. As one family walks out, a boy turns his head to glance directly into the eye of the camera just as he's about to exit the screen frame. (00:17:50)
Revealing mistake: When Richie shoots the random woman, as soon as he grabs her head and shoots her, it is clear that it's a dummy.
