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: When Paul comes to the table three chairs are free, when his father comes there is only one chair free - the third chair is suddenly missing. (00:49:30)
Continuity mistake: Helen's slipper is at about a 45° angle toward the right of the screen when Miss Willoughby finds it. When Detective Jimmy shines his flashlight on the slipper, it is facing the opposite direction. The second time Jimmy shines the flashlight, the slipper is at a steeper angle. (01:00:33)
Factual error: After the HEAVY rain and losing his supplies during the storm, Max (Royce's adolescent son) told his sister he needed to find two very dry pieces of wood to be able to make a fire. Everything in the woods would have been soaked, but Max quickly found two "very dry" logs and was able to make a friction fire (in record speed).
Revealing mistake: Based on the size of the dinosaur's back shown behind the 6' high cement enclosure, there is not enough room for the rest of the dinosaur's tail and the enclosure is not high enough to accommodate its neck and head. (00:16:29)
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)
Deliberate mistake: When James started to fall off the ladder, he tried to jump to reach the other side. Thom grabbed his right hand with his and was able to pull him to safety. James' weight and the force with which he jumped and swayed would have most likely resulted in James pulling Thom over the edge with him, and both being seriously injured or killed. (01:22:26)
Continuity mistake: The amount and color intensity (redness) of the blood on General Ford's facial cuts (nose bridge, cheek, forehead), as well as their precise locations, are not consistent and some° of healing appear to be chronologically out of order (e.g, freshly bled cut, scar, freshly bled cut). (00:57:32 - 00:59:34)
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.
Continuity mistake: A back view of the group of four-wheelers starting out driving through the field showed distinct tire tracks in mostly low, dry brown grass. Various other views showed little or no discernible tire tracks, tall lush green grass, and mixed dry brown and green grass. Even though the four-wheelers appeared to travel some distance, the end of the field that was visible from the onset was just reached. (00:21:35)
Continuity mistake: The angle of the laptop on the kitchen table changed (and no-one was close enough to have moved it). The laptop was initially more evenly aligned with the edge of the (round) table. A little later, the laptop was not visible, but probably should have been. (00:04:09 - 00:04:44)
Continuity mistake: There isn't anything immediately in front of the storage shed when Edee opens the door. Inside, looking out, there is some type of diagonal, long thin branches or vines extending to the ground, which are gone in the subsequent view. (00:09:42)
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.
Other mistake: Liam Neeson jumps into ice water to rescue his brother. He then painfully pulls his brother into the cab of the truck. Inside, he revives his brother after which they have a lengthy conversation. Liam's Mike McCann never starts the truck engine or turns the heater up, even though he and his brother are soaked to the skin and the brother is coughing up ice water from his lungs. In the next scene, both appear dry, in the same clothing, with no signs of hypothermia.
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.
Continuity mistake: When Tom knocks down the bike at the car, the position of the fallen clothes changes between shots.
Continuity mistake: While Porky is rapping, Al - G and Dom swap spots between shots.
Factual error: During the escape from the farmers market a red London bus is in the background. Those busses aren't used in Gloucester.
Other mistake: Narrating, Ringo said "Let me be clear. I never steal from people who don't deserve it." He was in a bank's safety deposit room, which was full of hundreds (if not thousands) of safety deposit boxes. Ringo was selecting specific boxes from among those along the wall, but he couldn't know whose boxes they were. (00:02:44)
