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: When the Doctor visits William Turner in Chelsea, he claims to be leaving by train from Charing Cross. That station did not open until 1864 - 13 years after the death of Turner.
Factual error: In a scene where Kat is flying to or from Northern California for college, in the background through the window on the plane one can see a commercial jet which has the winglets of a narrow-body Boeing, which were not introduced until 1998 on the Boeing 737 NextGen, rather than "wingtip fences" of an Airbus which were in use as early as 1985. Eve disappeared in 1988 when Kat was 17, so this would have been 1993 at the latest, when Kat would have been expected to have graduated from Berkeley. In the movie, it is suggested that this was just 2 years after her mother disappeared, so this would have been not later than 1990-91.
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: In the opening scenes where Margaret drives to San Francisco, her car is an early 50s Meteor. Meteors were a Ford Motor Company brand just above Ford (a bit like Mercury) but were sold only in Canada. Meteors often were only rebadged Fords, like this early 50s model. The rest of 50s and 60s car choices in the film seemed perfect.
Factual error: As the marchers start through the streets before they gather at the Edmund Pettis Bridge, they pass by a shop with a Pepsi sign. The Pepsi logo, however, is from the 1980s-1990s.
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: 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: When the guy is talking to him on the phone and the Russian smashes it on the floor, the phone smashes and the battery comes out but the guy other end can still hear him. (01:04:00)
Factual error: The newsreel at the start of the movie shows a carrier preparing to launch aircraft. The announcer claims it is the Enterprise, but in actuality, it is either the Lexington or the Saratoga, evidenced by the huge funnel.
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 the Germans come to the town a tank rolls through the picture. The first shot shows the tracks, then the whole tank is shown and one can see the tracks again. The turret suggests a Panzer III (which would be accurate for the time). It appears however that the tank is a modified Russian T34 or T55 or something as the road wheels are too big for a Panzer III. (00:13:00)
Factual error: While Evans and Eve are still in Grand Central they overhear an announcement which states "According to Port Authority policy This station will be closing for the evening." Grand Central is not part of the NY/NJ Port Authority. Also Grand Central is a terminal, not a station, as trains do not pass through Grand Central, they enter and turn around.
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: 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: The Royal Canadian Mounted Police officer who phones Jesperson to tell him he has not been accepted is a colonel. In common with most Canadian police forces, the RCMP uses British-style civilian police ranks (inspector, superintendent, etc), not military-style ranks as the American police do.
Factual error: When Felix reveals Roxy/Stacy's IP to the world, it is 195.243.245. That is not a valid IP, it is missing the fourth octet. (00:14:00)
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: 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: 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)
