Continuity mistake: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff. After continuing the story for about two minutes, the length of the ashes still have not increased when Amanda is about to take the third puff. (00:37:21 - 00:39:53)
Factual error: The pilot is flying from the left-hand seat. Helos are flown from the right side. (01:23:00 - 01:25:00)
Deliberate mistake: The oval mirror was in a depressed wall yet was able to reflect a window within the adjacent depressed wall. (00:18:23)
Factual error: During one scene, a police siren can be heard in the background. However, this was 1960/1 and police sirens were not introduced into the UK until 1963. Before that, police cars had bells.
Other mistake: After Jim shot the doe and found it lying in the snow, there were no visible deer tracks or dripping blood trail leading to the doe. (00:01:25 - 00:02:05)
Continuity mistake: The grilled cheese sandwich was charred while it was still cooking, but not when Jason's dad served it to him. (00:02:00)
Continuity mistake: Sergeant Hwang is thrown a javelin to stab one of the team members who assisted in getting the money. When he catches the javelin, his hand is placed over some tape that has been wrapped around it. The camera cuts to a different angle where his hand is now placed slightly above the tape. Then two shots after, his hand is positioned much further up the javelin. (00:39:03)
Continuity mistake: The amount/shape/size of the blood/cut on the bridge of Joey's nose varies, as does the obvious presence or absence of blood on the right side of his nose. (00:42:32 - 00:43:50)
Audio problem: When we are first introduced to Hayden lecturing the classroom, the shots from behind do not match the sound with the movement of his jaw.
Other mistake: The scraping sound is not coming from the man "scraping" his windshield. The snow is easily brushed off and there is no icy coating below the "fluffy" snow to realistically produce the sound of scraping ice off a windshield. (00:00:35)
Continuity mistake: Brahms was quite clean for having been buried under dirt and leaves. No dirt fell off Brahms' body when Jude pulled him out of his "grave" and there did not appear to be dirt in his hair. When Sean (Jude's father) held up Brahms, the doll looked relatively clean - or cleaner compared to when Liza (Jude's mother) started to wash him. (00:14:10 - 00:15:45)
Revealing mistake: The candles on the long dinner table are numerous and clustered, but linear in front views of people seated at the table. Based on how the candles are disorderly arranged, it would not be possible to show a couple or few candles spaced apart in front of one person. (00:05:35)
Continuity mistake: When Josh is watching over the tied-up Butcher, he's sitting on the couch, eating snacks and watching TV. If you look, you can see he has a cut on his face to the side of his mouth. When he gets up to get a snack, the cut suddenly vanishes and is missing for the rest of the scene. The actor must have cut their face right before they shot the couch bit, and then the rest of the scene was filmed either after it healed, or before it happened.
Character mistake: Deputy Becky told Sheriff Justin that Vivian's "been murdered." Discovering a dead body with cuts/scratches, a broken ankle, and a head wound (next to a rock with blood on it) does not automatically mean the person was murdered, and the Sheriff/police should have conducted a thorough investigation before making any conclusion about the cause of death. The death could have been accidental, such as by tripping while fleeing a wild animal. (00:11:55 - 00:13:29)
Continuity mistake: Running away from the guard after the burglary, Joey and Matt went down a fairly steep hill in the woods. After passing the hole, they walked up a small embankment to go toward home. The next morning, Joey is riding his bike down a steep hill (the one that was before the hole?) - so steep he has to get off his bike and push it. Halfway down, the camera shifts and Joey is suddenly on TOP of a small embankment, which appears to be the one he and Matt walked up the day before on their way home.
Continuity mistake: Theo lays Susanna's phone down - when it cuts back to her phone is lying in the opposite direction.
Other mistake: After Cami finds photos in Spencer's center console, she is able to see them while sitting in the back seat (perhaps from an interior overhead light). When Spencer approaches from behind and taps on her window, the interior of the car is dark and the photos are barely visible. Cami did not even try to hide the photos from Spencer, even though she suspects he was stalking her. (00:23:54)
Factual error: After Maya Peters is brought into the recompression chamber because of an injury, the timer is shown counting down by hundredths of a second and skips from 1 to 0 without showing 0.99-0.01. (01:24:30)
