Factual error: After sleeping in and being late for practice, Jack is driving to the gym. It is supposed to be morning yet the shadows made by the sun show the sun is setting over the ocean and therefore evening.
Continuity mistake: The kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
Continuity mistake: When Nick leaves to deliver presents he walks out the door and you hear the door close. When his wife goes after him with the flask you see him opening the very same door he's just walked out. (00:24:50)
Factual error: The movie is set in the 80s (you can see tell for instance by the driving license of the old woman, which uses the 80s template and has a 1985 date), but the police plays the suicide tape on a Panasonic PV-4614, which is a late 90s model of VHR. Same goes for the Sony video camera used to tape the murder, definitely from the 90s. (00:19:00)
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)
Continuity mistake: Theodore rides once the tiny rollercoaster; the cart comes to a full stop and his left foot is in the space between the bars, but in the next shot the left foot is on the outside. (00:48:00)
Continuity mistake: Theo lays Susanna's phone down - when it cuts back to her phone is lying in the opposite direction.
Continuity mistake: There are some continuity problems during the cafeteria scene where Fern is being introduced to her co-workers. Fern is holding a banana, peeled almost to the bottom, and has several slices of banana on her peanut butter sandwich. There is another banana peel on her paper lunch bag. Fern is shown taking a bite of her sandwich. A little later, Fern is holding a partially peeled banana but no slices can be seen on her sandwich. If this is her second sandwich, she already peeled two bananas. (00:05:59 - 00:06:32)
Continuity mistake: This is a little difficult to explain, so I'll do my best. When Char makes Millie/Butcher open the jail cell, in the first shot (a side-shot) it's clear that Millie is about to grab the third bar in from the edge of the door. When it cuts to the front shot, she's suddenly grabbing the second bar in. Then when it cuts back to the side-shot, you can tell she just let go of the third bar in.
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)
Continuity mistake: Maggie was holding two bottles (clear containing a green liquid) in her right hand and set them on the table together with one at an angle behind the other. She moved her hand away and when the camera shifted to a wide view, the bottles were side-by-side (horizontal to the screen) with more space between them. Also, both bottles were almost full, but had less in them when Maggie handed one to Grace at the airport. (Maggie may have had a sip out of hers, but not Grace's; both looked unopened). (00:03:33 - 00:04:25)
Visible crew/equipment: Sara is at the front door video intercom. As the man from the Department of Sanitation is leaving, you can see crew/equipment visible in the reflection. (00:27:15)
Continuity mistake: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
Continuity mistake: In the opening scene, the blue car is parked on the far right of the screen or at least one car length from the doctor's front door. Dr. Huggins says goodbye to the couple with the baby, who walk toward their car. After the burglars-to-be (turned robbers) are shown watching from a distance, the camera returns to the doctor's front door. The blue car is now near the center of the screen and it drives away toward the right of the screen - going past the place it had been parked.
Factual error: The manner in which "Hamby" fell into the hole (or well) did not reflect physics or reality. He was running/chasing Joey and Matt. Whenever one walks or runs, one's feet are never straight down together (like standing), so only one foot could have been over the hole or failed to clear it. Hamby should have tripped and fallen over (face forward) with his upper body landing past the hole. This should have kept him from falling straight down into the hole (as if dropped from above the hole).
Continuity mistake: The amount and location of dirt on Christine's face is inconsistent, ranging from being very thick and obvious to barely visible, if at all. Sometimes it extends down her neck on the right side. When her hair covers most of her face, no dirt is visible - until she turns her head and the hair is away from her face. The intensity and location of the redness on her neck also varies. (00:03:31 - 00:04:48)
Continuity mistake: At the "Wave Hair Salon", Ms. Gordon has a curler/roller at the top of her forehead. In some shots, it is straight, but in other shots it is angled. A little later, Christine goes over to Ms. Gordon and starts rolling down the curler to the top of her forehead as if for the first time. (00:08:04 - 00:08:47)
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.
Continuity mistake: The sizes, locations, and smoothness of the pieces of glass remaining in the wall mirror after Aidan smashes it with a bat change. Initially, there were a few large and several smaller jagged-edged pieces around the top and upper-half of the right side. Later, there were four relatively large smooth-edged pieces spaced around the upper half of the mirror - one in each upper corner and one on each side at the middle. (00:15:48 - 00:19:33)
Factual error: Joel is using a ham radio set to contact his old colony. A shot of the radio set shows it is set to "CW", which is Morse Code, but he is using voice. And the strength meter is on zero. It should be showing the signal strength. (01:24:00)
