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.
Factual error: After the naval battle, Thraex is waiting for an informant who tips him off about Lucilla and Marcus Acacius's plans. And of course, as a well-educated gentleman of 200 AD, he kills time by reading the newspaper. Wait, what? Needless to say (to anyone but Ridley Scott, probably), ancient Romans wouldn't/couldn't exactly get their news by newspaper, the press having not been invented yet. This one looks so modern in its layout it even has headlines and a proper publication title, "Roma Viridia."
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)
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.
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: 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 Deadpool is talking to Wolverine's skeleton, in one shot the skeleton's mouth is closed, but in the next shot it is open.
Visible crew/equipment: When Beetlejuice is first introduced, right before we see him, the camera rotates around the model and the sign above the grave lights up. Right before the sign lights up, you can ever-so-subtly see a part of the camera's shadow move over the model. It's subtle and easy to miss, but once you see it, it's pretty obvious.
Revealing mistake: We see Caesar's Palace in 1966. There are 1970s and 1980s cars in the driveway.
Plot hole: Robotnik and Grandpa Robotnik are dancing through lasers. The suits reflect lasers, but their heads are completely exposed.
Suggested correction: Gerald notes that the lasers are specifically conforming to the shape of his body, and Robotnik explains that the suits were designed to create a field that specifically attracts/distorts the lasers.
Factual error: The Torre delle Milizie is visible from the courtyard in the Vatican and looks fairly close. You can't even see the tower from the Vatican. It's quite a long way away.
Visible crew/equipment: When the car comes to a stop next to City Hall Park, there's a crowd of bystanders in the back watching the filming.
Factual error: The President and Agent Miles commandeer a small plane at an Astovian airfield to fly to Ramstein U.S. Air Force Base. Miles identifies the craft as Air Force One, as the President is on board. However, "Air Force One" is the designation only for Air Force planes that fly the President (similar to how "Marine One" is called that because it is a Marine helicopter). Non-military planes, such as the one they are flying, typically carry the call sign "Executive One" when the President is on board.
Factual error: Throughout the movie, we see soldiers at the air base control center communicate with the aircrafts using an RT-524 radio transmitter. This radio operates in the VHF range, which is not suitable for communication with fast jets due to the Doppler effect. To communicate with jets, you need a UHF range radio.
Continuity mistake: When Dr. Gallo is doing an echo on the pregnant Cecilia after she was assaulted in the baths, the cord of the probe is on either side of his hand depending on the shot. (00:40:20)
Factual error: She's driving down the highway, and her car suddenly and immediately dies, with no opportunity to pull off or park. When she gets out of the car, we see it sitting on the bare forest floor - not even a footpath, much less a road. 14. (00:14:30)
Continuity mistake: When Clay fights Anisette at the gas station, her heels change from stilettos to flats. Best visible when Clay throws her on a car, right after she says he should be retired.
