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.
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."
Other mistake: When they raise the temperature of the room with the facehuggers in, once the room is at body temperature, they open the door onto the much colder corridor. This would have immediately dropped the temp in the facehuggers' room.
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.
Other mistake: When Lydia tells the ghost Nadia that she's having a "really shitty day" with her back to the camera, you can see she's not really talking and is actually putting a pill in her mouth. The dialogue was just dubbed over it. It then cuts to a different angle and we see her repeat the exact same motion as she takes the pill a second time between cuts.
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: 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.
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 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 Deadpool is talking to Wolverine's skeleton, in one shot the skeleton's mouth is closed, but in the next shot it is open.
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.
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.
Character mistake: When the minion tries to get out on the top of the small car, it faces forward, but two shots later, it is now facing the back.
Revealing mistake: We see Caesar's Palace in 1966. There are 1970s and 1980s cars in the driveway.
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.
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.
Continuity mistake: In the staff room of the toy store, Callum gives Jack his Monopoly box to hold. The box does a 180° spin between shots, twice.
Continuity mistake: Kraven casually sniffs a couple and ruins their relationship. He then sits down with his brother; Fred Hechinger's hand keeps changing position between shots, holding a fork or not.
Continuity mistake: When Marcus is in the car, his grip on the phone changes between shots: sometimes he holds it with all his hand, but at other times just with his thumb and index finger. (00:14:58)
