Continuity mistake: At the end when Sarchie is hugging his wife, in one shot the bandage on his arm has unravelled. In the next, it is neatly wrapped.
Continuity mistake: When the crocodile catches the man he bites his right foot off. 5 seconds later as he falls into the water his foot is back. (01:21:05)
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)
Other mistake: In the flashback to Richard's childhood, when he looks from the door at his dad randomly shagging a party guest, the door appears open wider in the POV than it is in the other shots, where the opening barely fits his head. Besides, with the head in that position, he wouldn't see the door handle as shown. (00:02:00)
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.
Continuity mistake: At the Queen of Night's party in her garden, Bristle's outfit and appearance change, and the inkwell disappears. (01:42:05 - 01:43:00)
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)
Continuity mistake: Felix pushes the fire alarm button and exits the building. As his buddy Danny reaches him, it's obvious that multiple takes of the scene have been made, since some extras that were meters ahead of him are just passing him by at the very first cut. (00:04:30)
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.
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)
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.
Continuity mistake: There is a scene where she accidentally stabs someone - she gets blood all over her from the stabbing and then in the very next scene is wearing the same shirt without blood stains.
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)
Continuity mistake: Kevin Shepherd pulls over in front of her fiancee's dad. It's still a wide angle, but you can see distinctly both her and his left arm stretched forward; she is looking at her engagement ring, he has his hand on the steering wheel. Before the camera cuts away though, he lowers his arm; it is not acknowledged in the new shot, where both have still their left arm forward. (00:03:35)
Continuity mistake: When the young girl is on the beach removing her socks, she takes three socks off.
Suggested correction: Jess is wearing yellow socks with polka dots, and yellow wellies. There are three shots in which we see Jess removing or tossing her two yellow polka dot socks, and one of her yellow wellies.
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: 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.
Visible crew/equipment: When the little boy is lying in bed looking up at a hole in the wall you see a creepy hand move, the while time, if you look closely, there appears to be a human hand with human fingers to the right of it in the darkness.
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.
Plot hole: Tom told I.D. Halden, "My grandmother passed a few years ago and we inherited the family house." If there was a mortgage, who was paying it for a couple years? And if the house was inherited, there would not be a landlord, they would not be paying "rent", and owners do not get served with an eviction notice. (There was no mention of a legitimate reason, such as unpaid taxes.) There's a failure to discern home ownership (with a mortgage) from renting a house (which is not "inherited").
Suggested correction: It seems to be that it is about two different houses, the rented one they already live in, and the inherited one which is renovated.
