Factual error: In the poster shot and in the film, the wave from the Atlantic carrying the carrier JFK into a collision with the White House comes crashing in from the west because the south portico of the White House is seen. The Atlantic Ocean is east of Washington, so the wave should come from the other direction. And even a wave coming from the east could not have made the JFK (CV-67) crash into the White House because the carrier was retired in 2005 and is berthed in Philadelphia, which is northeast of Washington DC. (01:30:10 - 01:30:40)
Factual error: In the scene when the police are heading to Clyde's house to arrest him, this tactic is highly unrealistic. In real life, when a person is simply a suspect in an investigation, the police do not all drive to the suspect location with lights and sirens going. This loses the element of surprise. They didn't even know if he was home, anyway.
Factual error: In the original Transformers, Tyrese Gibson's character is credited as and wears the rank insignia of a USAF Technical Sergeant. In Revenge of the Fallen, set two years later, Gibson's character now wears the insignia of a USAF Chief Master Sergeant, three ranks higher than his rank in the first movie. The USAF would not jump someone three grades into the top 1% of the enlisted force no matter what his heroics or experience (that does not even happen to Medal of Honor awardees). Clearly the screenwriters recognized this as Captain Lennox is bumped only one grade to Major despite his actions in the first film and Gibson's character, as noted in another mistake, is credited as Master Sergeant Epps, a reasonable promotion. The costume department simply got the insignia wrong.
Factual error: During the first tunnel sequence, all the cars travel very far into the mountains, turn lots of corners, yet not only is Gisele still able to speak to them over the radios, their GPS still works. GPS signals invariably need a clear 'sight' of the sky and can penetrate light cover, but most certainly not that depth and cover. (00:58:05)
Factual error: In the scene depicting life on Baker Street (after the "Sherlock Holmes" title), a horse-drawn carriage races through the streets of London. The only problem is, the carriage is driving on the right side of the road with others passing on the left. In England, carriages would be driving on the left. (00:07:05)
Factual error: In the underwater scene when Rex blows up the ice pack, ice appears to be denser than water in this situation. The ice sinks when it's blown up, and even if there were pieces of metal on top of the ice, it shouldn't. Some pieces the size of a five-story building have no metal and still sink. (01:43:00)
Factual error: When the real German soldiers are playing 20 questions in the bar, one of the cards shows the name of Genghis Khan. This is an English-language word; as Germans, they would have written Dschingis Khan instead. As the whole scene deals with exposing the British/American spies and subtle differences in their language or behaviour, this is especially unfavorable here.
Factual error: Abby has trees surrounding her house yet there aren't any in Nome Alaska.
Factual error: At the start in 1989, when Mike is dancing with the cheerleaders and also just before he goes after Scarlet, in close-ups of the crowd cheering there is a man (with a white baseball cap) wearing a Paramore t-shirt. However, Paramore (a Grammy-nominated American pop rock band) formed in 2004. The style of t-shirt he is wearing is actually one of the officially licensed Paramore merchandise. (00:02:45)
Factual error: In the beginning a calendar says 2019 April, you can see April 1 being Tuesday when actually April 1 2019 was a Monday. (00:01:10)
Factual error: In one scene, focused on a period wood-staked pickup truck parked on the street, you can see clearly a modern Jeep Grand Cherokee parked on the other side of the street.
Factual error: In the scene in the 'cattle car' the shadow and light from outside the bars is moving across Kyle's face as he is talking. But unless the light source moves relative to the shadow source, a shadow will not move. But the light source was just outside daylight - and not direct sunlight - so the shadow inside would not have moved.
