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)
Revealing mistake: JR is in the weapon container of the crazy dealer, who passes him some of his goods. JR ends up holding in his right arm a MP5K and an M4A1, which combined are about 5 kilos, but then he passes him an M60 Machine Gun, which weighs over 10 kilos and that the relatively diminutive protagonist just handles throughout the scene gripping it with his left hand and making no effort whatsoever. (00:25:20)
Revealing mistake: Crawling through a fire cave you can see propane bottles in the background several times.
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.
Revealing mistake: Late on in the film; Arnie and the female officer kick in the door to one of his teams house. Unfortunately Arnie is in his 70s now and not as agile as he used to be, the door was open and simply pushed hard. Look at the door, it has no damage and neither does the frame. Also, the door barely opens past a hard push. As tactically trained operatives they would not have pushed the door if it was ajar either, they would have opened it slowly to avoid startling anyone inside and warning them.
Continuity mistake: Master Lui at his first appearance in the movie kills the traitor slicing his throat with burning tongs which he points right away at the eyes of the protagonist. Sammo Hung's grip on the tongs changes between shots. (00:11:00)
Continuity mistake: Treat Williams is drinking a brown liquid from a glass (scotch?) while accusing Gina Carano of having something to do with his son's disappearance. Shortly afterwards, the liquid is a different color and the glass is much more full. (00:41:40 - 00:42:40)
Revealing mistake: In the news reel detailing the Kohinoor theft, a few headlines appear, and at least one persists on screen long enough to easily spot the inconsistency between headline and article (filler text presenting a new local magazine from the London district of Lambeth). (00:09:00)
Other mistake: Prince Shing and the King have a conversation that lasts not less than 5 minutes of movie (which compresses the time somewhat; groups of people get in and out of the large hall, which wouldn't be instantaneous and happens at least 3 times). The conversation happens while the other members of the royal family are running away through a secret passage. With such a considerable head start and wasting no time (they keep moving even when they put mantles on), they are reached by heavily-armored guards, through the same secret passage, within seconds. (00:12:10 - 00:17:10)
Continuity mistake: When Nick is instructed to leave hotel room #700 Chord verbally tells him to "go outside and turn right." but the on-screen arrow points left and we see Nick turn left. (00:29:39)
Continuity mistake: When Paul steals the Camaro, he pulls wires out from under the dash to hot wire it. But after he gets his daughter he suddenly has keys.
Continuity mistake: The appearance/structure of the ground-level components of the well changes several times. In the first view, the unit is mostly gray and rusty with one vertical white pipe. When Ernest is pumping, half of the horizontal pipe is also white and clean. In the rear view, the vertical pipe is brown and rusty. Some mud spurts out of the spigot, but the spigot is clean, dry, and white in the front view. (00:05:10)
Continuity mistake: When the kids are looking at the Stonehenge-type structures, the younger boy calls for everybody to come and see the hidden message. From the shot in front of the boy you can tell from his body position he's sitting up, however in the next shot from overhead, the boy is now lying down on the rock.
Continuity mistake: Before Jesse's plate is placed on the table, the salt and pepper shakers are about a width apart. They are almost touching for a while, then back to being spaced apart. (00:10:20 - 00:11:00)
Continuity mistake: Everly puts the phone down next to the necklace she grabs. The phone is facing up, but after she wears the necklace, it's facing down. (00:06:40)
Continuity mistake: Near the end, Thomas is saddling a horse. He throws the stirrup over the saddle so he can cinch the girth. But he is interrupted by the presence of the witch he loves. Somehow, the horse has had its girth cinched and the stirrup is in its proper place, all without Thomas' help.
Continuity mistake: When the mother sees her dead son, she is behind the Sergeant. As the shot changes, she is holding on to the Sergeant and starts running to her son. (00:44:30)
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.
Other mistake: During the driving scene in the woods with the Bronco, at least two shots are reused twice.
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.
