Revealing mistake: Near the end of the film when Amanda and Dr. P almost take off together, there is a shot of them boarding. Look to the top right corner of the screen and for just a split second, you can see a glimpse of Roger chasing after them, along with Amanda's facial expression turn shocked. I'm pretty sure this happens because in the alternate ending Roger caught them when they were boarding.
Revealing mistake: During the scene in the bow thruster room near the end of the movie, Richard Dreyfuss rushes to the thruster tunnel access hatch to open it. As he grabs hold of the wheel, the hatch and frame visibly move, exposing it as the lightly built set that it is.
Revealing mistake: Just after Boog breaks the dam and the deer herd is bounding across the dry riverbed, at the moment they realize they are going to be swept downstream by the wall of water, their legs disappear - just left out of the animation cell. Very obvious; no slow-mo needed to see.
Revealing mistake: In the scene where Luigi offers his service to Van and Minny, Guido is juggling wheels. But when Guido finishes, you can see over his right lift that his one of his wheels is not rendered correctly, as it seems to overstep his bodywork.
Revealing mistake: You can see the charges to break the glass armor at the chest of the first guard when Violet kicks down in the vault. (00:16:30)
Revealing mistake: Right after McQueen asks what the Ghostlight is, it cuts back to the other cars. Luigi is right next to the firetruck and some gas pumps. The firetruck's door is very reflective, and the gas pumps are visible in it. But Luigi is right by the pump, and he is not reflected in the firetruck's door. (00:02:10)
Revealing mistake: The infant baby was computer animated in every scene in which the face appeared. Even the feet were obviously touched up by computer in the hallway scene. The lighting isn't quite right, the skin texture isn't quite right, and the child's face is just too animated.
Revealing mistake: When Stewart is working on his laptop at the satellite dishes, it is very obvious that he cannot type. He is tapping the keyboard repeatedly with several fingers, without moving his hands. (01:18:40)
Revealing mistake: When David Arquette is preparing to drive his rocket car, he does a u-turn to get pointed in the correct direction (towards his friend who is filming). The image is reversed at that point, so that he appears to be driving from the passenger side of the car.
Revealing mistake: In many of the scenes, particularly when Michael Douglas is leaving the cafe, you can see onlookers staring into the camera. A possible explanation is that few extras were used.
Revealing mistake: When Stella the skunk yells at the cat, she pokes him on the face. However, you will notice that the hand looks a lot like a human hand, not Stella's.
Revealing mistake: After Chris and his son learn that there are no more rooms in the shelter, the crowd begins to disperse. One homeless man touches a parking meter which moves easily, like a lightweight prop. (01:40:55)
Revealing mistake: After the accident, you see the car's gear is in park on the steering column.
Revealing mistake: Uhl talks about Eisenheim's childhood, and about the vanishing tree. Problem is that not only the tree disappears, but also his very own shadow, making him look as if he's floating in a landscape, thus giving away the green screen effect. (00:06:50)
Revealing mistake: During the final race, Wrangler is shown knocking a yellow car off the race course. A few seconds before this, there are two shots from behind Wrangler, that are just still frames. The shot does not show Wrangler driving or even moving and is completely still. The shot from behind is merely just a still image, that has been extended to last a split second. The same still frame image is also repeated two shots later. (00:27:35)
Revealing mistake: When Langdon comments on the geometric pairing of the two pyramids you can tell the point of the crystal pyramid is slightly to the left of the point of the other pyramid.
Revealing mistake: When Chev discovers he's been poisoned and picks up the TV, you can see it's not turned on, nor does it have any wires. (00:04:00 - 00:05:00)
Revealing mistake: After the scene with the apothecary where the two eunuchs purchased the belladonna it then cuts to Esther, and in her closeup as she lifts the silver cup to drink, there's a small white modern sticker on the underside of the cup. (01:02:00)
Revealing mistake: They let us see the stunt double's face for the girl Steven Seagal is fighting in the ending Cathedral scene, and she looks nothing like the actress.
Revealing mistake: The reaction of the jogger being hit by Clark's bat is way too late.
