Factual error: When Jonathan Groff picks up the .50ae, with a maximum capacity of 8 rounds, he fires more than 8 times. (00:35:00 - 00:35:45)
Factual error: After Mohamedou's torture scenes, the CO of GITMO holds up a letter from the Dep. Of Defense in Mo's face, stating that his mother had been detained. In the bottom left corner of the letter, it is written as "Department of Defence", which is the UK spelling. (01:41:27)
Factual error: The telephone for the phone bank doesn't have a phone jack cord connected into the back of the telephone. (01:15:14)
Factual error: Lady Gaga is painting her toenails listening to some music on her portable cassette player. It's 1978, and walkman-type players were introduced the year after. (00:11:00)
Factual error: The Black Watch sergeant major wears a crown over three chevrons, which was the correct rank badge for a company sergeant major until 1915. However, this is at least 1916 (as conscription has started and the men are wearing steel helmets, both introduced in 1916). CSMs had been redesignated as warrant officers in 1915 and now wore a crown on the lower sleeves instead.
Factual error: During the briefing, Waller shows the map of the island of Corto Maltese. The map positions the fictional island in the Caribbean (it says "Mar Caribe"), but she says it is "off the coast of South America." The map does have also a set of precise coordinates in one of the middle quadrants; 45°43'36.0"S 56°32'58.2"W, which would place it far west of Argentina, surely nowhere near "Mar Caribe." (00:22:10)
Factual error: There is a calendar in a scene towards the end of the movie which shows the date as Wednesday April 30, 2021 but the calendar does not align to the days of a real calendar. That date will be a Friday. (01:25:54)
Factual error: The scope Jim is using is completely wrong (yes I know he tested the wind using dirt) but as a U.S.M.C. Marksman his scope would have had mil-dots on both the horizontal and vertical bars. (00:04:24)
Factual error: There is a "Covered California" sign in a window. The referenced health insurance exchange did not exist during the 1990 time setting of the movie. (00:20:58)
Factual error: When "H" is shooting at the target, the paper holes are wrong. Bullets make clean precise holes on paper targets. (00:08:20)
Factual error: The Channel 5 WNP Newscaster said, "it is now believed he [District Attorney Berdido] and his family were killed..." and running along the bottom of the screen was "4 confirmed dead in Fort Lauderdale gas explosion." This was a LIVE report showing two streams of water onto the house still burning inside. An investigation would barely, if at all, be started at this time and no-one would be "confirmed dead" this early. It would not even be known if anyone was home when the house exploded. (00:04:34 - 00:04:55)
Factual error: Dr. Boxer is told the experimented upon baboon died. He asks that an autopsy be performed. Autopsies are performed on humans. A post-mortem examination on animals is called a necropsy. (01:01:45)
Factual error: The Sheriff's car had "POLICE" written across the rear end, but with the exception of Allegheny County, deputies in Pennsylvania do not have police powers. They are County employees who carry out court orders (e.g, serving warrants and subpoenas) and work in court houses keeping order. They also transport prisoners and issue gun permits. It would be atypical for a Deputy sheriff to do routine patrol like Deputy Myers was doing. The sheriff's car should have had "municipal" or government plates. (01:16:18)
Factual error: When the maid is shot with the shotgun, she flies back multiple feet. In reality, it would only be 1 or possibly 2 feet. (00:25:20)
Factual error: There was a lot of thunder and lightning before the lightning strike that set the barn on fire, but there was no obvious loud thunder AFTER the strike. Lightning can be seen BEFORE the sound of thunder (because lightning travels faster than sound). (00:03:25)
Factual error: "The Waltons Homecoming" is a remake of the 1971 TV-movie that led to the 1972-81 television series "The Waltons." In one scene, John-Boy has written a story for The Boston Arts Scholarship Competition. He addressed the envelope to "1815 Redwood St, Boston MA 02122." The movie is set in 1933. The Postal Service did not introduce ZIP codes and two-letter state abbreviations until 1963.
Factual error: Dylan (Scott Eastwood) was in a jail cell yet had a bottle of prescription pills in his pocket. The pills would have been confiscated before he was put in the cell and administered to him on schedule by staff/nurse. (00:28:10)
Factual error: The aerial view close-up of the large dome at the Vatican seems to lack features and isn't an exact replica based on on-line photos of the actual building/structure. The two smaller domes on the sides also are not visible due to darkening of the background. Other structures in front should be visible at that angle but are not. (00:15:26)
Factual error: All Arabic texts in the film suffer from wrong directional rendering. Arabic is a right-to-left language. Its letters have different joined and disjoined forms. The film, however, has rendered Arabic texts from left to right in disjoined letters. These texts aren't semantically wrong, though. For example, deciphering the Arabic message at 0:40:45 point gives "أليس "التنين فنان؟ Translation: "Isn't the Dragon an artist?" The film has even adopted a good font for them.
Factual error: Rock Doves - even those used to people walking around in the city and on the sidewalks - would have flown away at the first sign of a predator, including a puppy - but they more or less ignored Clifford running toward them. (00:10:30)
