Continuity mistake: The characters are on a tile floor that has one yellow tile visible among the black and white tiles. The next shot they're in a different spot on the floor with two yellow tiles visible. (01:22:10)
Continuity mistake: During the time Yoga Pants is wearing the mouth gag, her hair changes a few times from frizzy to neatly combed back. Also, if the mouth gag were as tight as made to appear, her long hair would not have been able to move away from the back to the sides of her neck and even into the front. (00:07:30 - 00:08:33)
Revealing mistake: After "Yoga Pants" unlocks a man's mouth gag, the man starts to unlock hers. Yoga Pants bends her head down and the metal rods in the mouth gag expand and slide out of her mouth before it's unlocked. She pushes her mouth gag back in place until the man removes it for her.

Factual error: The "real" Croatian license plate on the truck is only vaguely similar to the actual plates. Real plates start with a two letter city code, three or four numbers and then two letters.
Continuity mistake: Although not shown on screen, Crystal apparently put the shotgun shells in the right side pocket of her pants, but they were not in her pocket after she left the store. (00:28:04)
Continuity mistake: The amount and location of blood splatter on Crystal's white top after she shot Ma and Pops at close range in their store changes a few times. When she takes off the unbuttoned orange shirt she was wearing, she has little to no noticeable blood on her. Outside, she has several small dots of blood on her top that change to more blood spots in different locations when she is walking on the railroad tracks with Gary. (00:28:00 - 00:28:35)
Continuity mistake: After the man got shot with an arrow in his right shoulder, the arrow was sticking up almost to the top of his head. After he moved away from the fence and the camera returned to him, the arrow was not visible but should have been. The arrow is visible when there's a front view of him aiming his pistol, but the arrow is at a lower angle. (00:17:10)
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)
Factual error: It would have been impossible for the woman to have fallen into the hole on her own and get impaled by the stakes like she did. In order for the woman to land face-up on her back and get impaled by stakes straight up (perpendicular to the ground), she would need to be dropped from above the hole. Even then, the chances of getting impaled like she did would be around zero because her upper body, weighing more than her lower body, would fall faster and hit first at an angle. (00:14:33)
