Revealing mistake: When the guys are on the bench and the kid is taking a photo of them with the cell phone, when the scene cuts back to behind the kid before the phone is kicked, the phone is just on the standard main screen. The camera is not even on.
Revealing mistake: When the Federation fleet is preparing to warp to Vulcan, you'll see the first ship blast off, but the second ship blasts off out of nowhere. You could argue that the ship was out of sight and below the Enterprise, but the light trail isn't that long. The light trail starts in front of the Enterprise where you should be able to see a star-ship. (00:40:45)
Revealing mistake: The guy who takes the trash out of the club and bumps into Michael Myers, gets his head stamped on and squished, later appears in the film as the person introducing the Halloween party.
Revealing mistake: During the scene when Scrooge is sitting in his armchair by the fire, the animation of the fire is badly looped and you can see it flickering as it finishes a cycle.
Revealing mistake: When they are watching football, the mom walks in and says something to the family while she is holding 4 Pepsi cups in a cardboard cup holder with only one hand. If the cups were actually full, the way she was holding it it would have tipped over.
Revealing mistake: Just after the Buick spins around to knock the trailer loose, we see the Buick speeding away backwards alongside the truck. If you look carefully you can see the REAR tires are steering, not the fronts. This car was modified with the body mounted backwards on the chassis because the transmission only has one reverse gear, so to get the speed and handling needed, the car had to be going 'forward' with a 'backward' body. (00:05:30)
Revealing mistake: In the scene where Tucker takes off his fireman outfit, there's a waitress at the right side of the screen with four wine glasses on a tray. Gravity seems to have no pull on the liquid or the glasses, as both remain stuck even when she tilts the tray too far towards herself. (01:03:10)
Revealing mistake: In the scene where Brian Clough is at home you can see double glazed upvc windows, even though they were not around until the 1990s.
Revealing mistake: When Cora and Madea are driving the mini-van to go to anger management you can see that the gear shift lever is in the up or "park" position. The lever should be in the "drive" position.
Revealing mistake: When the Sheriff is in pursuit of the black SUV, there is a particular shot of the Sheriff's car doing a wide right turn and you can see that it's a young bald stunt driver, completely unlike the older, full head of hair Bruce Boxleitner.
Revealing mistake: In the scenes where Sam 1 and Sam 2 are in touch, the double is completely wrong. Wrong hair, wrong profile and wrong hind end.
Revealing mistake: When the soldier is tempering, you can see sparks fly before the hammer hits the metal.
Revealing mistake: When Julie is trapped in the bathroom with the "ghost girl" she is saved when some other girls come in and switch on the lights. However, if you watch the girl who flicks the light switches you can see the switches are already in the "on" position (pointed upwards) and she simply mimes flicking them up. (00:26:47)
Revealing mistake: When Georgia and Poupi are walking back towards the bus from the store where she buys food for everyone, several bystanders at both sides of the road just stand there looking at the camera. (00:17:30)
Revealing mistake: Nick's reflection is seen in the shiny ceiling, but the guns floating above him have none, revealing this to be a CG effect. (00:54:50)
Revealing mistake: During the nativity, when the baby is born, to the right of Mary, there is a boy tipping his candle on it's side. In the next shot, this same boy has the candle on his mouth.
Revealing mistake: The pic of Shawn's father and Evan on the PC seems very fake.
Revealing mistake: The movie shows in Matrix-esque slo-mo the double baton swing Goku dodges, from Fuller and his goon. They are nowhere near hitting each other, and yet, this missed baseball-bat swing causes them to KO each other in close-up. (00:16:55)
Revealing mistake: When Larry floats drowned in the pool, his face remains motionless until the very last second, when he starts to chuckle: probably a flaw of the actor straining for the last bit of air.
Revealing mistake: When Mr Goodall is attacking the bloke near the start, he is supposed to be hitting the other man really hard, but doesn't come close to hitting him.
