Deliberate mistake: In the pitch dark mansion dining room, the approaching zombie's screams are instantly interrupted by silence whenever the flame from Chris' lighter goes out, and then the screams instantly resume when the light returns. While this is obvious artistic license, for the record the level of darkness would have no bearing on whether we can hear the zombie screaming.
Continuity mistake: When Tae-ho is looking through the briefcase, he picks up a report file with Hyeonu Kang's name on the front. When he first picks up the report, his hands are placed on both sides of the file. In one shot, his hands are positioned towards the middle of the page, but in the next shot, his hands are positioned near the bottom of the page. (00:27:10)
Continuity mistake: When watching the water retreat after Sisu falls, a view from behind the characters shows Noi sitting on Tuk Tuk. The very next cut shows Tong picking her up from the ground. (01:18:01)
Factual error: When the Duke of Oxford (Ralph Fiennes) meets Rasputin, he notes how he "mastered the Bryozka glide", a dance technique where the practitioner looks like they are gliding a few cm over the floor instead of walking. However, while the scene is set in what must be 1916, the Bryozka glide was only invented in 1948 by Russian ballerina and choreographer Nadezhda Nadezhdina, who founded the Beryozka Dance Ensemble. (00:44:10)
Continuity mistake: When Jackson is shot with shotgun he "flies" across the bathroom, hits the wall, and falls into the tub on his right side with his left leg on top of the tub and leaning to right. Next shot he is on his back. (00:26:25)
Revealing mistake: The jaguar near the start jumps onto the bar and prowls along it. It knocks over one glass with some force, which shatters, but the second glass is barely tapped by its foot and it smashes to bits too, when it should just have been pushed out of the way.
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)
Continuity mistake: An exterior view of the window in the building across the street that the Virtuoso plans on shooting from shows it is comprised of three square panes stacked vertically. When the Virtuoso is inside behind the window, it is one large vertical pane. (00:10:27)
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)
Other mistake: Rebecca electrocuted the giant sand worm within 3' of the spaceship. After Lt Astrid arrives, some views show Rebecca out in the open, but the camera should have been obstructed by the spaceship because following front views still show Rebecca next to the spaceship. Also, at least part of the dead giant sand worm probably should have been visible at times but was not. (00:51:55 - 00:52:20)
Continuity mistake: The way Franck's scarf was wrapped and tied around his neck changed from when he was sitting on the steps (wrapped around a few times with ends folded under) to when he was standing along the guard rail (a loop down the middle of his chest). (00:15:09)
Audio problem: Obviously, the mouth movements won't match the English voice-overs, but when Yang Hao is singing "Happy Birthday" to his daughter Yuan Yuan, his mouth doesn't move at all. (00:05:50)
Continuity mistake: The rear of the steer carcass was on fire and smoldering, but not seconds later in the aerial view. Also in the aerial view, the position of the steer relative to Alexander was different. (00:06:00)
Deliberate mistake: The view looking out the windshield showed the man on the bicycle had stopped when he was in front of the car's passenger side, but the outside view showed the man still coming to a stop and then tilting his bicycle. (00:07:12)
Continuity mistake: When the convenience store is being robbed, the strap of the backpack on the counter changes its shape and position between shots.
Continuity mistake: When two officers go to inform Ronald Whitlock (Bruce Willis) about his sons, Ronald shoots his pistol at the Black officer and hits him near his inner right eyebrow. (A large black spot can be seen between his eyebrows.) When the camera shows the dead officer, the black mark is gone and the bullet hole is on his forehead centered about 2" above his left eye. (00:06:40)
Other mistake: While Snake Eyes is fighting at the beginning of the film, the other guy throws him to a block of concrete. Snake hits on his head and should be dead by then or at least seriously injured.
Character mistake: The interviewer pointed out that Evan [Mark Wahlberg] is a "smart guy" and another man later said, "Homeboy knows everything. He's a freak." When Evan was telling the interviewer the circumstances under which he assaulted a man, Evan committed a basic grammatical error - a misplaced modifier: "I asked him to leave politely." Evan didn't mean he wanted the man to leave in a "polite manner"; he meant he "politely asked" the man to leave. (00:09:20 - 00:14:00)
Continuity mistake: In the initial view of Billy in the tree ("saved for later" by the leopard sleeping on another branch), his head is hanging face up alongside a tree branch as wide as his head. When the camera zooms in showing the middle of Billy's face, the left side of the screen should be all brown, representing the branch. Instead, there is blue sky down to his eye and blurred tan/brown representing the branch. The brown might supposed to be the dried grass, but Billy has not moved his head. (00:51:25)
Other mistake: The issued sidearm for the Spanish National Police is the H&K USP 9mm Compact, which has a capacity of 13+1 bullets, and the Civil Guards' is the Beretta 92fs/M9, which is a 9mm and has a magazine capacity of 15+1 bullets. As of 2020 the Beretta is being phased out for the H&K USP C. The police officer fires a total of 5 bullets from his Beretta then the slide locks back because its dry. He has no magazines for reloads either. I highly doubt the Spanish police issues 5 bullets to their officers. (00:33:00 - 00:35:30)
