Factual error: They travel on a Boeing 777 to Amsterdam. The shots in the airplane are in a much smaller cabin (3 seats/aisle/3 seats). The 777 seating in economy class is 9 or 10 seats across, with two aisles. (01:29:00 - 01:30:00)
Factual error: In the scene where Katniss is being asked to make the first scripted propaganda video, they ask for wind machines to be turned on for effect. The blades on these fans start turning the wrong way (onto suck, not blow).
Factual error: The scene in front of the Sphinx shows the Sphinx without a nose. The nose was not missing until much later - most likely due to vandalism in AD 1378. (The story about Napoleon's soldiers shooting it off is untrue - sketches made in 1738 and published in 1757 show the nose was already missing, long before Napoleon's time).
Factual error: In the third scene, where the woman is being dragged away, you can see the incisions from breast enlargement surgery at the bottom of her breasts, hardly fitting the time period. (00:01:25)
Factual error: After Batman hits the Manbats with his sonar batterangs and they go nuts trying to escape the sound, some begin chewing at the glass separating them from the ocean in their desperation. This is in the under workings of an oil rig out in the ocean. Hundreds of pounds of pressure is on that glass. The Manbats chew through the glass, and then the water begins rushing in. All logic and laws of physics dictate that the Manbats would be pushed back, down into the oil rig further as water rushes in. However, as the water begins pouring in, 3 Manbats are somehow pushed out of the hole into the water, and are sitting still, long enough for a shark to grab one. Even if they did somehow manage to get out like that despite physics, the water rushing in the hole would have caused a vacuum and sucked them right back in. Yet they remain perfectly still in the water, only a couple feet or so away from the hole they just made.
Factual error: Scarlett and George use the Rose Key to translate the inscription on the back of Flamel's ancient tombstone, and it translates into a rhyming English lyric puzzle. Problem is, they are translating this lyric puzzle from Aramaic (an ancient and virtually dead Middle Eastern language) to modern English. Aramaic would not and could not translate into rhyming modern English.
Factual error: Though Maverick describes the helicopter he flies when he picks up the Mustang in Utah as an Apache, it is not one. The Apache is an attack helicopter, while the one flown is a cargo model discontinued in the 1970s. Furthermore, the livery of the aircraft has not been used by the Army for decades. Further still, the jets which intercept Maverick fly so close to the helicopter that their wake turbulence should have caused it to crash. A really heinous scene overall.
Factual error: Roland enters the train to go to the war, in 1914, with "Spanish Flu", but that was the (wrong) name given to the 1918 flu pandemic, which lasted from spring 1918 through spring or early summer 1919.
Factual error: When Nick, Kurt, and Dale are in Rex's closet, Dale appears to be turning on the gas. What he is turning is actually the screw to secure the regulator onto the gas cylinder. You can see the valve to release the gas at the top end of the cylinder. (00:46:30)
Factual error: During the Hungnam evacuation scene in December 1950, a U.S. Army Captain is using a radio handset. The model he uses is the H-250, which was introduced in 1987, over 30 years after the Korean War.
Factual error: The three panzers that ambushed the Hellcats are supposed to be Mk. III's with the 50mm gun, but they only had 5 bogie wheels, instead of 6, and no driver or radio operator's hatches.
Factual error: When Joseph Gordon-Levitt is playing poker, they are using Morgan style silver dollars. The stacks of dollars are treated as $100 dollars. But a Morgan dollar is 2.4 mm thick, a hundred dollars would be 9 .44 inches high and the stacks of coins were about half of that. (00:11:00 - 00:12:00)
Factual error: The alien drops the video camera out of the UFO from outer space and it falls to earth landing on the ground. This very far drop would certainly have busted it to pieces, if not ignited it on reentry, but when the guy picks it up off the ground, it appears only the screen is cracked.
Factual error: A scene shows a 1980's Ford Crown Victoria with New Jersey license plates. They start with QQ which means it's registered as a historic vehicle which means it has to be at least 25 years old. The film is set in 1999.
Factual error: In a classroom scene, Mia takes her phone out and checks Instagram. It can be seen that she is on the network "Koodo" - a Canadian mobile operator. The movie takes place in Portland, but is filmed in Vancouver. (01:00:10)
Factual error: Declan takes a gun from his glove compartment and nothing else. I counted that he fired 22 shots before being put down. There is no way that gun had a 22+ round magazine.
Factual error: Ryan Reynolds has an entire trailer of evergreen trees that he is going to plant in the middle of the winter. No landscaper would plant trees at this time because the ground is frozen, and if planted they would die.
Factual error: The first kill in the movie - the king who is dead - has rubber soled boots with modern treads.
Factual error: The streak ended in '04, but at the beginning of the movie the seniors talking about their last game have letter jackets with the year '05 on the sleeve.
Factual error: In the scene where James Brown receives a new Cadillac from his manager, the scene is marked by a 1965 timeline header, but the Cadillac is actually a 1967 model.
