Continuity mistake: Rachel's hair and the amount/location of loose strands of hair are quite inconsistent throughout the movie. The gas station/ convenience store scene, in particular, shows a lot of variation while inside standing by the cash register. Strands from her hair (not really bangs) go diagonally across (from right to left) her cheek and sometimes down her neck or even to her lip. Strands of hair also hang down from in front of her ear and the back of her neck (while hair is tied up in a bun). Almost every time the camera returns to Rachel, the messiness of her hair (dangling strands over her face and neck) changes. (00:28:28)

Continuity mistake: As Rachel approaches the gas station, the road is divided by an intermittent yellow line, but it is a solid yellow line when Rachel is getting into her car to leave. The road also varies in wetness, sometimes being quite wet but other times dry (er). A quick change from wet to dry occurs when Tom runs down the male customer who tried to help Rachel. (00:28:18 - 00:31:49)

Continuity mistake: Before Tom exits his truck to break into the house (ex-wife's or her new boyfriend's), he has what appears to be a smartphone (or other flat rectangular object) in his shirt's left pocket but it is not in his pocket when he exits the house. (It is not likely that he took time during the bludgeonings to remove the object from his pocket and leave it behind at a double-homicide scene and the victims were not able to fight back and knock it out of his pocket). (00:02:35 - 00:03:52)

Continuity mistake: A front view of the house showed there were no lights on before Tom broke inside. After Tom whacks his wife's new boyfriend and then is heard off-screen killing his wife, there are still no lights on in the downstairs room to the left of the screen. Tom comes back into view by the front door and pours gasoline around the room to the right of the screen and sets it on fire. When Tom comes out of the house, the light is on in the room to the left of the screen. (00:03:27)

Continuity mistake: A few minutes after 4:00 AM, Tom whacks the front door with a hatchet / tomahawk - almost instantly an upstairs light is turned on, and by the time it takes for Tom to take a couple steps into the house, the boyfriend and ex-wife are just feet away from Tom. The two people inside the house somehow managed to instantly wake up from the bang on the door plus travel half-way across the house and go from upstairs to downstairs without using the "vertical" staircase! The distance they covered in such a short amount of time (a few seconds?) was absurd. (00:00:47 - 00:01:36)

Continuity mistake: The amount of rain on The Man's shirt is relatively light when he reaches the doorstep but his shirt was saturated before he even started going up the sidewalk. He was in the house for a couple of minutes to kill the two people and set the house on fire (not enough time for his shirt to dry) yet his shirt was almost dry when he exited the house. The Man's shirt got soaked again on his way to his truck. The shirt looks dark blue when saturated with rain but light blue when it is dry. (00:02:53 - 00:03:51)
