Revealing mistake: When the final race is under way, the silver Saleen S7 hits a Police SUV and makes it flip, you can see the smoke coming out of the bottom of the SUV where the cannon has fired to flip the SUV.

Revealing mistake: When they are in the hospital van, taking the senator to triage, and they receive fire from the helicopter, one announces that "Randall is dead" referring to the young man in the back of the van. It then cuts to his corpse - however, a split second before the scene changes away from his face, his eyes move towards the camera. (00:56:35)
Revealing mistake: As the Predator tends to his wounded leg, one of his claws can be seen bending as if made of rubber.

Revealing mistake: After Nuclear Man destroys the cab's hood, the shot changes and there's a thick string running behind him all along the car, and the cab driver is stretching out to pull it. Probably he was activating some sort of bad FX.

Revealing mistake: During the opening trap, at one point one of the five "Bucket Heads" starts banging on the wall behind them. If you look very closely, you can see the set-wall waver slightly as it's struck, revealing it's not really a concrete wall. (And it's not supposed to be the doorway that is later revealed during the final twist. It's a separate section of wall). (00:05:40)
Suggested correction: No it's not the section that is a door, but that door does prove vital here. By showing the door, shows there is a section behind the wall. Meaning the wall we see is most likely a completely false wall and not the structural wall. With it being a false wall it is entire pleasurable that it could move.
When Jigsaw opens the door, you can see the walls are indeed solid and are at least 6-8 inches thick. Given the fact they appear to be made of concrete and run floor-to-ceiling, sorry... there's no way they are moving when someone bangs on them. Also, why would Jigsaw make a "false wall" that was so easy to move when someone hit it? He'd be setting himself up to possibly be caught. Sorry, but this particular correction is just too far-fetched. It's just a mistake.
Revealing mistake: When a baddie in a red jacket repeatedly punches Hightower, who's in the water, the fist always stops about 15 cm from his face.

Revealing mistake: In the final Indian chase at the conclusion of the film, when a covered wagon rolls over, one can see the rope that was used to ensure it tipped over.
Revealing mistake: Mirrors were used to make the corridors appear longer, early in the film when Brett is complaining to Parker about the way they are treated by the company you can see their reflections in the mirror behind them as they walk down the corridor. It's only for a second as they are moving off camera but you can see them in their white overalls.
Suggested correction: She doesn't put her foot in its mouth. She instinctively tries to kick it or she's just unlucky with where she moves her foot.
Mortug
She put her leg in the shark's mouth. It's too obvious even without slow motion.
