Factual error: The film is based during the Battle of the Bulge which took place from December 16th 1944 to January 25th 1945. However throughout the entire film the area appears to be mid-summer. No snow in sight. (00:07:50)
Factual error: After the introduction, there's a scene supposedly happening near Lausanne on the Lake Geneva, but in fact it's altogether the wrong canton, Ticino and most likely Laggio Majore, a couple of hundred kilometers away. (00:06:00)
Factual error: When the high-ups at the Pentagon are looking at the profiles of the terrorists, Ulrika's profile contains a minor spelling mistake ("Americas" instead of the possessive form), but the fun is in her henchman's file. The guy is named "Grigori Babishkova", which is laughable since "-ova" is the female suffix for Slavic last names, he should be "Babishkov." The Nationality field lists him as being "Russian/Caucasian." Caucasian is not a 'nationality'. (00:05:05)
Factual error: The first kill in the movie - the king who is dead - has rubber soled boots with modern treads.
Factual error: Newgate makes a reference to Mickey Finn's name being the same as that of a Chicago bartender who used to drug his patrons with knockout drops. However, the film is set in 1899, but the real Mickey Finn wasn't caught until 1903.
Factual error: Set back in 2004, there is a scene where Shapelle and her friends are looking at an accommodation website. If you look closely at the laptop screen, you can see that they are using the Google Chrome browser, however the first release of Google Chrome wasn't until September 2008. (00:06:30)
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: In the opening heist, the gang of thieves wants to steal "The Medal of Zeus." A plate at the museum explains that in Ancient Greece, Olympic champions were awarded olive wreaths, up to the 88th Olympics in 424 BC, when a golden medal was given to the victor for the first time. This last bit about gold medals is just made up by the movie. But it also gets the timeline wrong; the 88th Olympics were in 428 BC. 424 BC is when the 89th games took place. (00:03:30)
Factual error: Narration refers to Hitler's Germany research into nuclear fusion - it was nuclear fission they were looking into, the same as what fueled the WWII-ending bombs in Japan, and every nuclear bomb and missile since. No nation has been able to generate nuclear fusion until very recently, and it doesn't produce an explosion - which is what Hitler wanted. (00:08:35)
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: When they torch the car by the docks, supposed to be about 15 years in the past, there is a US Navy Independence-class ship in the background, but the first of these was only launched in 2008, at least 9 years after the scene was supposed to depict. (00:35:00)
Factual error: In the scene in the basement during the storm Dale is running the projector on house electricity. The lights go out and he switches to a battery which must be 12 volt. He runs the projector on that current, which is impossible.
Factual error: The British Major is wearing a RAMC (Royal Army Medical Corps) cap badge (incorrectly mounted). Really, not a British Army Corps known for their sniping skills.
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: There are actually no dinosaur remains at the British Museum. There used to be, many many years back, but they were removed to the Natural History Museum, which is about 3 miles from the British Museum.
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: 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: 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.
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: Just like in the previous movie, Herzog is referred to as "colonel", in particular in the WWII museum where Martin reads about his history. But both in the museum's picture of him, and throughout the movie, Herzog is wearing the uniform of a SS Standartenführer. To hold a title of Oberst (colonel), he would have been a member of the Wehrmacht, regular army, not SS.
