Other mistake: In the frame you can see the girl is playing on a newer Macbook, she is using a wired headset but the headset is not plugged into the laptop, you can also see she is using a wired gaming mouse, and the USB cable is just sitting there not connected to anything. The Macbook is USB-C only and the mouse is USB-A.

Other mistake: At the beginning, Jack reveals that he has lots of food allergies and asks the bartender to prepare his shake lactose free, implying that he is allergic to dairy. But later he eats a snowman cookie that Mrs. Claus reveals has butter in it.
Suggested correction: Being lactose intolerant does not mean you're allergic to dairy. It means you lack the enzyme (lactase) needed to break down lactose and usually results in gas or an upset stomach. However, butter is high in fat and low in lactose, so a lot of lactose intolerant people can eat butter or food containing butter just fine.

Other mistake: When Lomito was holding the little green ball with the smiley face on it, her flashlight was shining on her fingers/fingernails - all of which were long and manicured. The length of her fake fingernails - even if they did not exceed the department's policy on maximum length, such as one-fourth inch past the fingertip - probably were long enough to interfere with her ability to quickly put her finger on her pistol's trigger and shoot; the length interfered with her ability to perform her duties. (00:31:25)

Other mistake: Mara has white shoe laces in her navy or black Converse high-tops. After the car crash and Mara gets out of the water, her shoe strings are dyed pink. Mara's white top has turned pink or magenta, supposedly from the blood getting diluted when she was trying to wash it off in the water. The shoe laces may give the impression that they, too, turned pink from diluted blood, but the pink or magenta color is not how diluted blood would look. Besides, the white soles and toe tips stay white. (00:31:00 - 00:34:12)

Other mistake: When the white mouse runs to save the brown mouse, he runs at normal speed, but the witches move in slo-mo for reasons unknown. (00:47:23)

Other mistake: Fran is unconscious near a gas stove as Marla comes to save her. As Marla is trying to move her, Fran moves her leg even though she is supposed to be unconscious.

Other mistake: Jack took Illinois licence plate "BL 91021" off a Subaru SUV to put on the group's truck and put "V 986394" on the Subaru. Illinois truck (< 8,000 pounds) plates have the letter "B" on the middle-right side of the plate. The "BL 91021" would have too many numbers to be valid. By putting a license plate starting with "V" on the SUV - without the letter "B" on the middle-right side - the SUV would not have a truck plate like it should (and would also have too many numbers to be valid). (00:22:49)

Other mistake: Rayburn pulled an arrow out of his chest - and without much blood gushing out. The rather small amount of blood on the towel and Rayburn's ability to go about business as though he had not been injured is unrealistic and absurd. (00:27:00)

Other mistake: Alpha was standing at an angle to the senator when he shot him in the forehead, but the bullet hole was not angled as would be expected. Alpha was also holding his gun slightly upward when aiming at the senator's forehead, but the majority of the (odd-shaped) blood splatter behind him was near the back of his neck instead of higher. All blood splatter went behind the senator, but some should have been in front. (00:21:05)

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)

Other mistake: In the opening scene where Joey is breaking into Ms. Dillard's house, he quickly smashed a window with his flashlight and immediately crawled through the window - without checking to see if shattered glass fragments were still in or around the frame. Despite his carelessness, he did not even get a cut on his hands or elsewhere, which would be almost impossible under the circumstances.

Other mistake: The entire movie takes place during the overnight dark hours. Limited lighting from the car and flashlight somehow manage to illuminate faces, photos, signs, etc. Filming in the dark surely has its challenges, and there has to be a proper balance between lighting and ability of viewers to see what is happening. The "convenient" lighting would be a "deliberate mistake" except for one factor: A full moon (highly illuminated) is shown without radiating the light expected from a full moon. (00:26:25)

Other mistake: A crow crashed into a bedroom window, causing a small hole in it with radiating cracks. There was blood splattered around the hole as well as two long downward/ vertical lines of blood. Although it is possible for a bird to crack a window, it is much more likely that a bird breaks its neck without causing damage to the window. In the event that this crow did put a small hole in the glass, at least some fragments of feathers should have been stuck around the hole, but there were not any. (00:06:55)

Other mistake: Near the beginning of the movie, John's neighbor, Ed, is standing behind a wooden fence that is diagonal across the screen. The fence behind Ed is straighter. The angles of the fences indicate they are too close together - perpendicular sides of fences do not form a "V." Also, two BACK sides of fence are shown. Since Ed is within the fenced area, it is his (not John's) fence and the front ("good") side of the fence should be facing John's yard.

Other mistake: Bo walks through the charred corn field, but her shoes do not get sooty. When she finds Eden's flower ring, the flower petals are intact, but should be burned beyond recognition. (01:25:18 - 01:25:39)

Other mistake: If Grace had Billy at age fifteen (without his father in the picture), has worked as a receptionist in a law firm, and undoubtedly had been missing a lot of work due to her failing liver, her house and furnishings would be well beyond her means.

Other mistake: The woman was impaled by two stakes, one through her chest and one through her right shin. The man pulled her out of the hole from the edge at an angle to her left side. From this position, he could not have initially kept her body parallel to the ground or subsequently pulled her up at an angle without causing additional injuries or death. (00:14:33 - 00:14:55)

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)

Other mistake: The opening credits show a bit of Ava's rather extravagant biography. She is involved in a DUI accident that kills two people; the news article says that it happened "early Thursday morning." What follows is a police photo labeled 06/27/95, a Saturday. Then we see the police report; not only the incident time is 10:30 PM, but the date is March 15 1999, which was a Monday. It is not separated incidents, since the police photo is then shown again, next to the "Thursday" article (and the fact described in the article is life-changing). (00:08:10)

Other mistake: Based on where Carol is standing near the top of the stairs of her new apartment, more of the couch behind her should be to the left of the screen (like it is in a later shot). (00:48:10)
