Continuity mistake: As Steve and Mike are leaving in the police car, Mike turns and puts his arm back as he looks back to start driving in reverse as Steve waves to his wife. It cuts to an angle from behind his wife as Steve puts his arm down, but then Mike turns and looks back again a second time in this shot to start backing up. (00:20:35)

Deliberate mistake: An LAPD cop discharges his firearm a full size Glock which has a minimum magazine capacity of 13+1 for the Glock 21. The Glock 21 is approved LAPD issue along with other variants. He fires maybe three shots and the slide locks back signalling that it's dry. A second later the same cop is walking with the same empty Glock aimed towards the suspect which was shot at. It's visible that the slide is being held back by the slide stop since the magazine went dry. (01:29:58)

Character mistake: During an intermission following Dmitri's revenge after the attempted hit on him, the Chief of staff discusses the data with Dr. Updale. There's a pie chart in the screen in the background, and the segments are; 5%, 25%, 16%, 14% and 50%, which add to...110%. It's not a pie chart, it's a pie and a slice. (00:50:15)

Other mistake: Daphne's dad drops the Legitimate Tulip badge in front of her so she'll avoid getting hurt, but when we see him do that, he does it before the warning for the ball is heard and seemingly not looking at the danger (especially in the second shot, when he is peeking from the corner). So his action makes no sense. (00:16:55)

Factual error: Max could not have been accidentally shot when Annie drops the revolver. She dropped it when she was startled by firing it into the ceiling so the hammer would still be sitting on the spent/empty shell casing. The trigger or hammer must be pulled back in order for the cylinder of a revolver to rotate to the next live chamber.

Continuity mistake: Some figurines on Lidya's nightstand changed positions near the start. The rabbit was moved closer to the front, then back. The blue object was moved back a couple inches. (00:03:15 - 00:03:58)

Revealing mistake: The anchor rope around Maddy's neck is loose enough for her to remove.

Factual error: When the saturation divers open the outer hatch on Kursk, they drop a glow stick. When they do, it falls to the floor on the submarine, indicating the inner hatch was open. The inner hatch of Kursk was closed, later opened by an ROV.

Character mistake: When recruiting Burt to help repel the Graboid attack in the arctic, one of the team members says he's ideal for the job because of his experience hunting them on two continents, a reference to the first two films (Nevada and Mexico in North America) and Tremors 5 (Africa). However, this repeats the mistake in Tremors 5 in overlooking the Argentina incursion stopped by Burt at the beginning of Tremors 3, which gives him experience fighting Graboids/Shriekers/Ass-Blasters on three continents, not two. Burt, himself having overlooked Argentina in Tremors 5, does not correct her. And it's not as if the film is completely ignoring Tremors 3, since it shows the flashback of Burt being swallowed by a Graboid in that movie, which is how he got infected with the deadly parasite killing him here.

Factual error: Spoiler! The cultists burned Mandy alive by wrapping a sleeping bag around her, putting gas on her and hanging her from a metal swing set and setting her on fire. After Red frees himself later and craws up to her remains, it's shown that she is barely a pile of ash with her skull still somewhat in shape when he picks it up. It then crumbles into just ash showing she had been fully burnt to the very center. This would not have been the case with how they burned her. Their was nowhere near enough heat or kindling to keep her body burning long enough to turn completely to ash with no remains like that. She would have died, yes, but would have mostly stayed intact as a single body burnt very bad. Bones, features, charred organs would still have been left behind. (01:04:00)

Continuity mistake: Waikiki lowers Honololu's gun telling him that the caveau won't open. There's a reaction shot of their hotheaded accomplice holding his gun with both hands and tilted. In the background of the next shot, he's holding the same gun with just one arm. (00:01:50)

Continuity mistake: The main character is exercising in the gym and in the background is a man on the abs machine holding the handles above the grips. In the next shot he is holding the grips, and then next shot back to above the grips. (00:38:00)

Continuity mistake: When Phil heads to the Puppet Pleasure place early in the film, the positions of the shadows change around the vehicle parked out front in the close up, revealing the time laps between filming each shot. (00:06:30)

Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.

Continuity mistake: Green Lantern traps Doomsday into a vice grip and the monster looks up at him glaring as it starts struggling to break free. It jump cuts to a different angle just before Doomsday busts out of the vice and suddenly he's looking straight forward instead of up at Green Lantern. (00:42:55)

Continuity mistake: When Stallone kills the bad guys with skull masks in the corridor of the bar, his motions pointing the pistol don't match the positions of the lemming-like goons he hits. For instance he has the gun all the way to his right for the first one he kills, but the guy is shown with a hole opening in his forehead while he's in the middle of the corridor. (00:29:00)

Continuity mistake: When they reach the plant in Mexico and Richard is introduced to the plant manager and his right hand man, Richard points to him with an empty hand. In the next shot before he points to the other guy, suddenly his cellphone appears in his hand that he's pointing with. (00:17:00)

Continuity mistake: Felix on his skate jumps over a rolled-up rug some movers are carrying in the middle of the street. He jumps and the street is in the shade, he skates away and the street is full of sunshine. (00:01:30)
Revealing mistake: At the beginning of the movie, the protagonists dump the corpse of an agent in the middle of nowhere. The guy is stone cold dead...but you can see the carotid pulse on the right side of his neck, under the fake blood. (00:03:10)

Continuity mistake: When Priest and Georgina throw the molotov cocktails at Juju from the balcony, watch closely - right as Priest throws the second molotov cocktail and the camera cuts from a bird's eye to a ground-level angle, the position of the two men and the carpet they're standing on changes between cuts.
