Revealing mistake: When Kershaw is driving the car from the passenger seat, as the car crashes through the roadside stands, you can plainly see a stunt driver driving the car.
Revealing mistake: When Gatsby and Tom are racing (a CGI achieved scene), note that the passengers' hair barely moves. (01:32:00)
Revealing mistake: Anthony turns on Jason and shoots him. Jason dies on his feet and falls to the floor. Even after some time passes in the scene, there is no blood around his body at all. (01:16:40)
Revealing mistake: When Oz first meets the Munchkins, some of them begin flipping down some stairs. The animation of this is very jerky and noticeable. (01:20:30)
Revealing mistake: Montana gets a call from Sam who is informing her about Damon Diesel. The camera shows Montana rushing up to the phone which is on the table. When the phone rings it is not on the call screen, it is on the contact page. Shortly after Montana's mother comes and leaves Montana glances at the clock and hurries to call Sam. She raises her phone to her cheek and ask "Sam what's the flight number?" If you look closely, the call is not actually being made as her cheek is pressing different icons on her phone. (00:23:55 - 00:25:40)
Revealing mistake: When John attacks the 3 bad guys in the residence area, one of them throws John into the wall which wobbles. (01:00:35)
Revealing mistake: During the big shoot-out at the end, the close-up of the brown Ford pickup is flipped side to side. Check out the F150 logo on the fender, which appears as a mirror image.
Revealing mistake: Toward the beginning of the movie when they go to Pricemart, you can see Benny's written across the back wall in neon red letters. Benny's was the real store where the scene was filmed. (00:07:20)
Revealing mistake: KantMiss puts the chicken badge in her sister's hand. Actually through her hand, since it stabs her with a long and sharp pin. But as she holds her hand, the long piece of metal is gone - it's perfectly fine for the characters to suddenly heal from one scene to another since it's a crazy spoof movie, but here we are midway through a visual gag and the nail is missing while the girl is still screaming in pain trying in vain to pull free. (00:04:00)
Revealing mistake: Close-up views of Billy riding Allie on the mini-bike (trying to escape the men following in the Jeep) did not include the lower half of the mini-bike; they were probably on a platform/trailer being pulled by a car. A 12-year-old (?) boy would have difficulty steering and maneuvering a mini-bike with a rider similar in size/weight and would have undoubtedly wrecked when he turned his body around from the waist up to look in back of him at the tailing Jeep. Billy also kept turning the throttle. (00:25:40)
Revealing mistake: When Ginger and Augie get into the limo nearish the start, it's obvious the street has been closed for the filming of the limo driving down the street because the limo driver goes across a red light. You can't see the red light directly, but you can see the green light on the opposing street.
Revealing mistake: In the scene where Jake is about to enter the boat, he is hiding in a trailer so he can sneak up on one of Pope's men. When he jumps up, grabs the pole and stabs him in the chest with it, you can see it doesn't go through his chest, but instead it just goes in between his arm and his rib cage. You have to look closely to see.
Revealing mistake: Whenever Ralph is driving Travers in the limousine and the exterior of the car is seen in a long shot, there is no one riding in it other than the driver. From every view point of the windows that can be seen, there is no passenger inside where Travers is supposed to be seated.
Revealing mistake: Robin is running away from company investigators. He comes across a supposed wire link fence. He breaks it with his bare hands, and by the flapping of the open piece you can see it is made with strings not wire.
Revealing mistake: Not bad digital effects for a combination "Predator" and "Jurassic Park" monster movie, except that the dinosaurs don't cast shadows about half the time.
Revealing mistake: When Brooke arrives at the camp to drop off Steph and Chrissy, Chrissy leans out of the car and vomits, but you can see that she's not really vomiting, and is using her hand to cover up the special effects tube.
Revealing mistake: Pablo and his buddy are driving through the middle of nowhere, and end up in the bucolic town of Red Stone. The first two people they drive by are armed with machetes. The close-up of the second one is reversed, as shown by the dilapidated street sign - it can't be deliberately shown by say, the car mirror, because they are looking at him turning their head. (00:05:40)
Revealing mistake: After Alex shoots the intruder in the head, killing him, a couple of shots later you can see his chest slightly expanding and contracting, showing that the actor was still breathing.
Revealing mistake: When Charlie and Lindsay are having sex, almost when they're done, a horse gets into the bed. The horse disappears too soon.
Revealing mistake: Just after Superman and Supergirl have their talk about him going after Brainiac, it cuts to Lois at the Daily Planet on her laptop. There is a close up and you can see her fingers on the keyboard. She is typing really fast, but the animation shows her fingers just hitting the same 3 or 4 keys over and over again. (00:20:05)
