Continuity mistake: Right at the start after they dock with the escape pod, three people enter and Kanelo calls out for Franklin. The guy behind Kanelo shines his flashlight to the right of the screen, but when it cuts to a close up of him, suddenly he's shining it towards the left of the screen. (00:03:15)
Continuity mistake: The middle curtain on the passenger side of the RV is pulled open to different extents (toward the sides) when Drake is snooping around. Depending on the camera's view, maybe a foot of the curtain can be seen to the right. The other views show much more of the curtain, indicating it is not pulled to the side as far (and might possibly be closed). When a larger amount of the curtain is showing, there is also a small section of a pleat partially on the sill. (00:04:00 - 00:04:27)
Deliberate mistake: The movie is set in "Harburg County", Pennsylvania, but there is no county in Pennsylvania called "Harburg." (00:13:38)
Continuity mistake: In Alice's apartment the clock on the wall has the time as 8:40 when she is standing and kissing David. They have sex and Veronica comes over. Alice and Veronica talk and the clock still shows 8:40. (01:20:00)
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)
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.
Other mistake: During the murder in the stairwell, an old woman opens her apartment door outward, and Varg kicks it shut. Apartment doors always open inward, as did Euronymous' apartment in the same building.
Suggested correction: Euronymous' apartment door opens outward into the hallway, at least in the final scene it does when he's trying to get away from Varg.
Character mistake: Immediately after the crash, when Reeves is carrying his youngest child Sophie, the actress opens up her mouth, even though she has already drowned. (00:14:43)
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: When Kurt sees Elisabeth playing the piano naked in the living room, he is shown walking through the doorway. The camera then cuts to focus on Elisabeth and in the background of the shot, Kurt can be seen walking through the doorway a second time. (00:12:30)
Revealing mistake: Davey at the beginning of the movie is looking at the newspaper he's delivering to Mr. Wayne Mackey. Just from a glance at the page you can tell that something is off, since the article supposedly about a missing boy appears to be written entirely in first person. Upon closer inspection, turns out that it's filler text from chapter IV of Robert Louis Stevenson' s "Treasure Island". (00:01:30)
Factual error: Cat Rivers is flying the R44 helicopter from the left seat. The R44 is a single pilot helicopter fitted with dual controls. Two collective levers may be installed (the left is removable) but the cyclic control is not of a conventional nature. This comprises a central stick terminating in a pivoting T bar, which only allows one of the pilots at any one time to control the cyclic with the hand grip in the 'normal' position. The R44 is normally flown from the right seat; it is possible to fly from the left seat and instructors regularly do so. Students and low experience pilots would normally only fly from the right seat, and are discouraged from flying from the left seat when with friends. This is because of the unusual cyclic control configuration and, to some extent, the different instrument scan and visual references for hovering when flying. (00:14:40)
Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.
Other mistake: It is highly unlikely that police, investigating the dead body (of a man reported missing) with a gun shot in the mouth and cut forehead, would simply back off after asking a mother if they could talk to her sixteen-year-old son (and son of the victim) and she said "no." (01:40:35)
Factual error: Second scene, caption says "1977 southern California" but she's driving a white 90's Oldsmobile Cutlass Ciera Fwd station wagon.
Continuity mistake: The four strips of tape on Lukas' forehead are closer together when he goes into the kitchen than when he exited the bathroom. (00:15:43 - 00:16:31)
Continuity mistake: Ron Perlman and Famke Janssen are having dinner on his supposed birthday. The whole meal has several continuity errors, with her fork being at different heights, sometimes replaced by the wine glass, etc. (00:34:30)
Continuity mistake: The fourth time Jess raised the cigarette to her mouth, it was about half the length that it was 5 seconds earlier; cigarettes don't burn this fast. (00:47:45)
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: In the basement when the girls are talking, one mentions to Chloe that she and Carl would make an adorable couple. Chloe's left arm is stretched up above her head in this shot. But in the next shot when she corrects her on the guy's name, it's suddenly down by her lap. (00:06:10)
