Revealing mistake: Candace's eyes are moving and she is breathing after allegedly having been shot and killed.
Revealing mistake: Near the end of the movie when everyone except for Peter dies. Lucy is supposed to be dead, but we can still see her breathing.
Revealing mistake: After Wallace kills the Scottish noble in bed, he jumps out of the castle window into a river on a horse. As he is falling, you can see that the horse is a model and when they fall into the water one can see the fake horse bobbing around. (02:15:45)
Revealing mistake: Mrs. Doubtfire sets herself on fire. When she jumps back and starts fighting the flames, it is obviously a stunt double as her face is longer.
Suggested correction: If you look carefully, the face looks pretty much the same, as well as the voice.
The reason the voice was the same is that it was probably an audio dub, which is a voice recording over someone else's voice.
Revealing mistake: When Hightower is in the Monster Truck you can see that a white stuntman is actually driving it in one of the shots.
Revealing mistake: When Syd and the Haitians are running, there is one shot where skid marks are visible on the road in the exact place the Haitians skid. (00:27:40)
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: 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: When the stripper appears from the changing room during the cabaret scene, the stripper music is heard, but if you look carefully the tape recorder which is supposed to be playing the music is not actually moving.
Revealing mistake: In the scene where Themistocles first talks to Queen Gorgo, in the background you can see several extras, one of which is wearing obvious sneakers. (00:18:35)
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 they're trying to get rid of the bat at the cabin, they hold up a sheet to force it out of the door, however when they reach the door, you can see the bat being pulled up with string or wire.
Revealing mistake: When the driver is taking Amanda to the airport at the end, all the dials on the car are at zero, so obviously the car is not moving at all.
Revealing mistake: When Jack is doing a search for "Andi Garcia" on Google, the links show up in the searches he does as purple and not blue which means that they have already been visited, despite the fact that he's supposed to be doing this search for the first time.
Revealing mistake: When the bridge is exploding from the mine attack, the stuntman playing Jason obviously launches himself out of the captain's chair.
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: During the scene on the banana boat, the woman who is attacked by the shark quite deliberately shoves her leg into the fake shark's mouth as it missed her when it came up out of the water.
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.
She put her leg in the shark's mouth. It's too obvious even without slow motion.
Revealing mistake: When making traps, he's harvesting powder from a spent shell (primer has been struck). (01:05:50)
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: After Jim's horse is shot from under him while running down the really steep hill, and Jim later regains consciousness, before he turns and finds his horse dead, if you watch closely you can see the horse still breathing.
