Factual error: After the train crash, the teen characters discover cube-like items. One of them states it looks like a Rubik's Cube. The movie itself takes place in 1979, but the Rubik's Cube, although invented in 1974, was not licensed to sell in the USA until 1980. It was not even called a "Rubik's cube" until 1980 (prior to this, it was known as a "Magic Cube"). (00:21:55)
Other mistake: So let me get this straight: Optimus Prime has Energon Swords hidden in both of his arms, with which he can slice through an entire Decepticon in one chop, yet when he is hanging from a few wires, despite having one arm entirely free, he can't cut himself loose?
Factual error: Winter in Antarctica would not have a night and day as portrayed, with the amount of light changing so much during the course of 24 hours.
Factual error: Erik arrives in Argentina at a place called Villa Gesell, shown to be a town in middle of mountains. Villa Gesell is a beach town on the Atlantic Ocean coast, with no mountains.
Factual error: When the action moves to England after the failed award ceremony, the British Union Flag hanging from the wall is upside down. The broad white band should be at the top left (nearest the top of the flag pole).
Factual error: When Nate dies by the alien moon rocks, his helmet visor "explodes." The visor in the film shatters like glass, but the real visors on actual spacesuits are made of polycarbonate, a plastic that does not shatter but deforms.
Factual error: When a global map is shown, the location of Toronto is incorrect. What is labelled as Toronto is actually the location of Montreal. (01:08:05)
Audio problem: This scene is repeated multiple times in the movie: usually when the main character enters the "source code" the scene begins by panning over a small pond showing a Canada goose taking flight. However the sound editor makes the mistake of dubbing in a recording of a hen mallard duck.
Continuity mistake: When John sees his photos on Sarah's website, the lower row of photos shows him throwing a football. However, when Sarah took those photos earlier, she only took out her camera AFTER he threw the football, while John was already talking to Sam.
Plot hole: In the last car-chasing scene, the timekeeper had switched his car to chase them, then how could Justin Timberlake get the timekeeper's salary (a day's time) from a car that the timekeeper picked up from the streets?
Suggested correction: I think it is the car of another time keeper. Hence, it may have a time transfer system.
Continuity mistake: After meeting Elise on the bus and getting his Blackberry dumped into his coffee David Norris calls his friend Charlie with his "spare phone" (silver). But after a cut or two you can see that he uses his BlackBerry again. So he has changed the phone during the conversation AND his coffee BlackBerry seems to be working again. (00:19:20 - 00:20:10)
Continuity mistake: When the bird first hits the RV, a blood stain is visible on the windshield. But on the exterior shot of the RV as it stops, the blood has disappeared. (00:26:50)
Continuity mistake: In the scene on the Golden Gate Bridge when the apes are pushing the bus, the police shoot the bus numerous times, but when the camera goes off the bus and then shows the bus again (twice) the bullet holes are not there anymore.
Plot hole: Everybody jumps into the water and emerges on the submarine except for Natalie. They're wondering where she is when they notice a flare. They realise it's her, and they send a search party. She's hiding on a bus maybe one to two kilometres away from the water. Her going there makes no plausible sense. Makes no sense how she held her breath underwater longer than anybody that they didn't see her and why she would go in the opposite direction of the sub. It was done to prolong the scene. (01:09:00 - 01:18:00)
Factual error: Upon hearing that the bombs will drop in 3 hours time on Santa Monica, one marine sets the countdown timer on his watch for 3 hours and starts it. The watch is a Casio G-shock GW-9000 Mudman. This particular watch only has a 1-hour countdown timer. (00:24:15)
Continuity mistake: During the film, Daniel Craig's character rides out to the house where he last saw the woman he was in love with. During the wide shot showing him on his horse riding toward the camera, the device on his wrist is missing. It is obvious if you are paying attention, as he is using the arm which is supposed to have the device to hold the reins of the horse.
Continuity mistake: When Tick Tock freezes Rebecca and Cecil, they are in one position, and when they go to the close up of them frozen, they are in a different position. When it zooms back out again they are in the first position. Also, when they are frozen moving on the conveyor belt, they are back in the position they were in on the close up shot. (00:47:50 - 00:48:10)
Continuity mistake: During the first round of the Zeus versus Atom fight, as Atom gets knocked down for the third time he initially falls onto the very edge of the WRB logo in the centre of the ring. Yet as soon as the camera changes angles Atom is lying much further in on the logo.
Continuity mistake: When the trio are about to enter the maintenance tunnel under the cargo hold, there is nothing in the tunnel. Morgan tosses a single bag in to start crawling through it, but she crawls over another bag already in the tunnel. (00:57:30)
Continuity mistake: When Hal is showing his friend how the ring works and has to "recharge" it, his grip on the lantern changes between shots. (01:09:45)
