Factual error: The way surveying is done is plain stupid. Percy Fawcett sets up a transit in the middle of a thick jungle, Henry Costin stands 10 feet in front of him holding the rod in one hand and a notepad in the other, then Percy looks through the transit and somehow reads the geographic coordinates out of thin air. This scene repeats couple of times during the movie.
Factual error: During the ceremony on Liberty Island at the end of the movie, Chief Vincent wears three stars on the lapel of her dress blouse. In actuality, an NYPD chief would wear stars on her shoulder plate.
Factual error: As Ray is driving around the country selling his machines, we see town mileage signs that are green with white lettering. In the early 50s they were white with black lettering.
Factual error: When Mike is being questioned, he calls himself a soldier. Marines always refer to themselves as Marines - soldiers are the army. (01:01:20)
Factual error: The EMP burst would have only affected a small number of vehicles. Most vehicles act like a Faraday Cage.
Factual error: When researching Christian Wolf in the IRS database, they state he made $75,000 and ran ZZZ Accounting. They then look up 3 other businesses with over a million dollars in income, said they were all partnerships and stated that Christian Wolf was managing partner. Given that partnerships are flow through entities for income tax purposes, all that income would flow through to individual returns, resulting in much more than $75,000 in income on Christian Wolf's tax return.
Factual error: As Moana ages from a toddler to 16 years old and her grandmother ages and gets grey hair, Pua the pig and Hei Hei the rooster do not age at all. Hei Hei should not even be alive, considering roosters normally live just six to seven years.
Factual error: The character Red Harvest is a Comanche. He is sporting a Mohawk haircut. This hair style was not in use by the Comanche tribe, but used by the Iroquois and Mohawks.
Suggested correction: The Mohawk hairstyle was used amongst many different plains tribes as well as eastern tribes.
Factual error: Virtually all of the CGI animals in this film are rendered at about 150% of their natural size. Additionally, even a small gorilla could tear the strongest human limb-from-limb, so Tarzan wouldn't have lasted two seconds in a hand-to-hand combat with an alpha male gorilla.
Factual error: Himmler incorrectly refers to the Nazi Party as the National Socialist Democratic Workers Party. The proper name is the National Socialist German Workers Party. (01:08:10)

Factual error: The 2 C-class Mercedes Benz' they have in the CIA compound are the newer body styles that came out the year they were filming the movie. The Benghazi attack happened in 2012, the C-class had a different body style then.
Factual error: The film is set in 1987 and Eddie ends up in hospital. However the bed we see him on is a fairly modern one with hand controls to raise and lower the bed. Not available in 1987.

Factual error: The tailplane of the crashed German bomber is a HE177. The film is set in 1943, the HE177 didn't operate over Britain until 1944.
Factual error: Towards the end of the movie when the hotel keys are handed out, they're IHG hotel keys for the Crowne Plaza. When the incident occurred, the cards would have been Priority Club, not IHG. (01:34:10)
Factual error: In the opening shot of the movie while our characters are driving down the street in 1951, there is a post-2000, white Toyota Tercel. It's the 2nd car on the left. The car is removed from the next scene. (00:00:50)
Factual error: At the start we see some neon tetra in the background. Tetra are fresh water fish. Not saltwater. (00:05:00)
Factual error: When Desmond's father is in his WW1 uniform, to the far right he is wearing a French Croix de Guerre (Cross of War) - the medals themselves are identical however, this decoration incorrectly hangs from a WW2 type ribbon.
Factual error: There are a number of errors in the Irish rank insignia. The general wears at various times three bars (worn by a captain in 1961, when the film is set) and a modern major-general's rank badge (introduced in 1971). The junior officers wear British-style pips (not introduced by the Irish Army until 1971). The company sergeant wears the rank badge of the lower rank of company quartermaster sergeant.
