Plot hole: The world depicted features magic, an evil overlord who 2,000 years before tried to conquer the world, and several races. Despite these HUGE differences with our world, everything turns out of the same as our world, with nations as they are now, and a casual mention of the Alamo and "Mexicans still getting shit" for it. So our current history has not been altered a single bit by wizards, dragons and super-strong races roaming the Earth. Fine. In this ungodly implausible context, orcs live with humans in cities that mirror ours; humans and elves don't trust them, but still they live in towns with them, they go to schools, run businesses, half of the NFL is formed by orcs. Even the movie Shrek exists! And yet, at the end of the movie Nick Jakoby becomes the first Orkish police officer in the USA! There is just no way a society like this, mirroring closely our own and with orcs that existed as long as humans did, can exist with no orc ever been part of law enforcement.
Continuity mistake: Selene normally wears high heel boots. They briefly turn into flats during her caged fight with Varga, right before he betrays her. (00:26:40)
Continuity mistake: When Noah and Adam are talking and Noah is playing with his fishing pole he is reeling it in. It cuts to a close up as he talks about his mother taking him to Canada and suddenly his left arm is pulled back a bit and he's holding the pole much closer to his body. (00:08:20)
Continuity mistake: Jake and Wendall are talking on the track field as they pull some weights. The strap attached to Wendall's glasses keeps moving in front and behind his shoulder between shots. (00:03:30)
Continuity mistake: Man-seob smears some cream above his upper lip after a few smoke grenades are deployed. The amount of cream shown over his upper lip changes between shots.
Continuity mistake: When Emily is in the US Embassy in Bogotá, the guy tells her he is the only one there. However, when he first started talking to her, there are two men in the background. (01:58:00)
Continuity mistake: In the mid-credits scene in Justice League vs. Teen Titans, Terra's hair was shoulder length and she had no freckles, but in this movie, she now has shorter hair and freckles.
Visible crew/equipment: When the police woman falls off the boat when the shark hits it, on the right side of the screen, you can see a hand outstretched, as if reaching out to grab her. It doesn't belong to the only other person on the boat, since he's behind the wheel and completely out of reach. So, it belonged to a person who wasn't supposed to be there.
Continuity mistake: The candle to the far right in the candelabra is tilted to the right to various degrees or not in between shots. (The other candles aren't exactly straight up.) In one shot, the candles are further apart (not paced the same distance between them). The top half of the candelabra was tilted to the right when the right candle was leaning against the wall. (00:24:27 - 00:25:20)
Factual error: The film informs us the gravity on Neptune's moon Triton is less than 8% of Earth's. But the whole physics of the rocks and his movement on the surface do not reflect that. The actual surface is frozen nitrogen. The difficulty he has in moving around is not well correlated by him only weighing 7kg. Https://www.imdb.com/title/tt5361488/.
Other mistake: When the Polish police officers are shot in the van, there is no blood splatter at all. Two seconds later there is blood on the wall. When the guy in the middle is shot in the chest, blood sprays almost one meter above and behind him on the wall. (00:33:25)
Visible crew/equipment: When they get into the tunnel/water drain, you can see the crew on the left side when switching the scene. (00:39:00)
Factual error: Just after feeling the explosion from the south tower, Eddie's watch shows 17:37 whilst others and himself are stuck in the North tower elevator. The planes hit the towers in the morning. (00:35:00)
Continuity mistake: When Ray starts to levitate in John's house, he looks down and he is hovering right above the table with the couch to his right. In the next shot, the table has suddenly vanished and it's now showing that the wall across from the couch with the TV and chair are on his right. (00:20:25)
Factual error: Will's Range Rover has a rear New York license plate but not the required front plate. (00:08:25)
Continuity mistake: During the initial briefing, the digital clock initially points the time pretty accurately, but then gets stuck on minute 56 for way too long; it's at 12:56:35 when they whip out of the drug lord's folder, 20 seconds of dialogue elapse till the clock is shown again at 12:56:47, another 25 before it gets to 12:56:55, and about 40 seconds before it gets to...12:56:56. And barely 30 seconds pass before Estrada arrives, at exactly 1 o' clock. (00:12:30 - 00:14:30)
Continuity mistake: When the boy wakes up in the middle of the night after first hearing the dinosaur, his alarm clock reads 2:0x (its not clear but the digit segments on show imply it's either 2:05 or 2:06). The next time we see the clock it's 2:02, then two scenes later when the dinosaur decides to and then does jumps off the table the clock now reads 2:22.
Other mistake: Five people are walking in the forest to find a new place to stay. One person is not carrying anything. A child is carrying a camp lantern. One man is carrying a medium size duffel pack. Of the remaining two are one leading an injured man with a bandage on his eyes. No packs. When they make camp the have a large tent, a camp stove, a pot, and a sleeping bag, even fishing poles and gear. No way would all that fit in the one bag.
Deliberate mistake: The front passenger's side mirror [driver's side is on the right] is parallel to the screen/camera yet there is a perfectly clear image of the passenger's face looking into the mirror. (00:00:38)
Continuity mistake: While racing through a parking complex to get to his daughter at the hospital, Lin ramps out of the exit and hits the font of his car on the ground leaving some damage, and even a part of the bumper hanging off. However in subsequent shots, the vehicle is undamaged. (00:02:50)
