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.
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)
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: Mr. Shamsher at the beginning of the movie steps out of the helicopter with one door open, but when he brings across the other leg both of the large doors are suddenly open at the cut. (00:03:00)
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)
Factual error: When Connor is describing his 1970 LT-1 Corvette,, he says "Holley and Rochester Quadrajet carb." Those are two different brands of carburetors. (01:05:39)
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: After Willoughby wrapped a necktie around Don's wrist and crossed the ends to hold it together, it fell apart when Don lowered his arm. But the necktie was securely wrapped when the camera shifted to showing Don putting his arm around Willoughby's back. (01:36:40)
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.
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: 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: When the doctor with the satellite phone runs to the car, he is being chased by another member of the team, and of course the graboid. Look ahead of the graboid. The path it will take is visible.
