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)
