Revealing mistake: When Wolf Jackson touches a headstone as he and the police are about to raid the church, you can see the headstone wobble when his hand lightly touches it, revealing it to be made of a soft, perhaps Styrofoam-like material and not a real headstone.
Factual error: In the diner, the kids listen to/dance to Britney Spears' "Toxic," which didn't release as a single until January 2004. This takes place in 2003.
Continuity mistake: After Rain shoots all the xenomorphs in zero gravity, and she and Andy have to traverse through the floating blood splatter, the bodies of the dead xenomorphs have suddenly disappeared.
Continuity mistake: When Deep Dark Secret breaks the jar to free the emotions, look at where the emotions are standing, and how the huge piece of glass lands behind them. In about three seconds, the piece of glass changes position, and some of the emotions switch places. (00:33:08)
Factual error: The movie, by various accounts, takes place 300 years after the apes took over and humans were rendered "dumb" (both literally and in the (non-PC), mute meaning of the word) or went underground. But yet they're making contact with a communication satellite. Satellites don't function for 300 years; they require occasional course corrections to keep from entering the atmosphere and burning up. Course corrections require propellant. The propellant wouldn't last 300 years. And the electronics.
Deliberate mistake: When Lucius is shown Maximus' tomb, the painting on the wall reads, "What we do in life echoes in eternity," in plain perfect modern English language. Of course, it helps audiences relate to the first movie, but it's ludicrous, to say the least.
Continuity mistake: Lady Raven arrives at the Coopers' place and starts talking to the wife. Cooper's watch is set to 1:35. An instant cut later it's set to 1:20.
Factual error: Ian Fleming explains to March-Phillipps that the U-boats need "fuel and torpedoes, but they also need carbon dioxide filters, for oxygen." U-boats didn't have CO2 filters. They had the air on board when they dived, which, along with the batteries supplying the electric motors they used when underwater, limited the time they could remain submerged. There were several instances of U-boats being forced to surface after long periods of being depth charged; their air supply had been exhausted. (00:12:00)
Continuity mistake: When Jessica kills the sniper with the rock at the beginning, the sniper's body is lying dead on the ridge. When she shuffles down the dune to speak to Paul, mere seconds later, the sniper's body is no longer there. (00:09:04)
Revealing mistake: When Elly is "skating" on the black oil while fighting the bad guys, we can see that it is Bryce Dallas Howard's stunt double in a few shots where it briefly shows her face.
Continuity mistake: When Deadpool is talking to Wolverine's skeleton, in one shot the skeleton's mouth is closed, but in the next shot it is open.
Revealing mistake: We see Caesar's Palace in 1966. There are 1970s and 1980s cars in the driveway.
Other mistake: Irs stabbed Richard completely through his face and shot him in the torso. Although he fell in the lake, he is later shown on the shore and he is not bleeding. Head wounds normally bleed like crazy. Since he is wounded in two places, he should have drowned or bled out from swimming to shore. (01:19:51 - 01:25:08)
Audio problem: When inside Washington D.C. and the AH-64 is firing its gun, the sound is completely wrong. In the movie, it sounds like a laser gun, and in reality, it's a M230 chain gun, which sounds different.
Character mistake: Characters frequently refer to there being crocodiles living in the water. Alligators live in Florida, not crocodiles. And although they are closely related, they are not the same species.
Continuity mistake: When the milkman is drinking milk in the bar and talking to the Tony the Tiger actor, the amount of milk in his glass changes with the different camera angles. It goes from 2/3 full to mostly full to half full back to mostly full. (00:54:56 - 00:55:45)
Plot hole: Given contestants were carefully checked for steroids at show time, mainly by urine tests, it seems unlikely Jackie would have been allowed to compete once her steroid use was discovered.
Suggested correction: Not at the amateur level, and not during the time period depicted in the movie.
Continuity mistake: After the bad biker bites Noel, he removes the rearview mirror from the windshield and smacks the bad biker with it. However, when Noel tells Katie to drive the car, in the exterior shots as she sideswipes another car, the rearview mirror is back up on the windshield; then it's off again. (00:33:35)
Revealing mistake: In the first scene, they skid around a corner; there are many other skid marks on the same corner from previous takes.
Character mistake: Early in the film, Sister Paxton reveals that she wants to come back as a butterfly after she dies. Reincarnation is not a tenet of Mormonism.
