Continuity mistake: Whilst running through the hallway, Jen slips on some blood and falls over. The shotgun lands on the floor right next to the wall. Two quick cuts after, the shotgun has changed position, moving to a different part of the floor. (01:41:40)
Revealing mistake: When Jen and Richard are chasing after each other through the house, some of the shots of them running appear to have been repeated to give the impression that they are running in circles. Specifically, the shots of Jen running through the living room, the shots of Richard running through the hallway and the shots from behind Jen running out of the door in the hallway. (01:41:15)
Continuity mistake: When Richard has Jen pinned against a wall, the POV shots of Jen facing Richard show blood running down her field of vision, but in the other shots, there appears to be nothing covering her eyes at all. (01:42:25)
Continuity mistake: When Dimitri is attempting to drown Jen in the river, she takes his knife and stabs him in the eyes twice. The first time, she stabs him in the left eye. The second time, she stabs him the exact same eye and lets go of the knife. It then shows Dimitri with a stab wound in his left eye and the knife in his right eye, even though it should be in his left. (00:46:05)
Continuity mistake: When Dimitri pushes over Jen after she tries to shoot him, she lands on the ground. In the long shots, her arm is in the water, but in the other shots, she is on the land. (00:44:45)
Continuity mistake: In the cave, Jen cracks open a can of beer with her left hand. The camera changes angles to a close-up shot and she is using her right. (00:50:35)
Continuity mistake: When Jen is in the cave, she opens a can of beer and foam begins to spill down the side of it. The shot cuts and the foam has suddenly disappeared. (00:50:40)
Continuity mistake: When Jen has finished having a drink of beer in the cave, she puts the can down and has her left hand on the wound from where she was impaled by the tree branch. In the next shot, her left hand is suddenly on the ground. (00:50:50)
Continuity mistake: When Jen attempts to remove the tree branch from her body and fails, she lies down on the ground. When the shot cuts, she suddenly has her head lying on her hand, even though it was not there in the previous shot. The position of the locket also changes between shots. (00:51:40)
Continuity mistake: When Stan runs back to the SUV after he discovers Dimitri's body in the lake, there is a blood stain on the windshield from where Richard had dumped an animal carcass. The appearance of the blood changes between shots. (01:00:10)
Continuity mistake: When Richard tells Stan to turn off the air con and help him, the windshield of the SUV is mostly clear due to Stan wiping off some blood from the windshield using the wipers. As Richard walks back to Dimitri's body, the windshield is mostly clear, but when it cuts to a close-up shot of the car mirror, a blood stain has suddenly reappeared. (01:02:35)
Continuity mistake: When Stan gets out of the SUV to help Richard with Dimitri's body, the windshield wipers are switched off. When the two walk back to the SUV a minute later, the wipers are suddenly moving again. (01:02:35 - 01:03:35)
Revealing mistake: When Richard punches Stan, a blood splatter comes from his nose. He falls back and blood is over his face and his hands. Just after he is first punched, his hands are already covered in blood as he is falling back, before he touches his face. The blood was most likely applied to his hands separately before filming the scene as it was never visible on his hands at any point earlier on. (01:03:35)
Revealing mistake: When Richard and Stan are driving across the desert, there is a shot of Stan driving the SUV. The number plate and Range Rover logo appear to be reversed and the driver seat is shown on the right hand side instead of the left hand side, revealing that the shot has been flipped. (01:04:40)
Continuity mistake: When Jen climbs out of the cave, she is holding a shotgun in her left hand. The camera then cuts to a closer angle where her hand is suddenly further up the shotgun. (01:08:20)
Continuity mistake: When Richard and Stan split up, Richard walks over to his motorbike and Stan continues to keep looking at him. In the next shot, Stan is suddenly looking straight forward in the opposite direction. (01:11:40)
Visible crew/equipment: When Richard tells Stan to get the map out, Stan walks over to the SUV. As the camera pans across the SUV whilst Stan walks over to the door, the reflection of the camera can be seen on the window. (01:10:15)
Continuity mistake: When Richard leaves Stan to split up, Stan is shown with nothing in his right hand as Richard walks over to his motorbike. Once Richard starts the motorbike, a walkie talkie has suddenly appeared in Stan's hand. (01:11:40)
Continuity mistake: When Richard starts explaining what the peyote is, Dimitri is smoking a cigarette and then begins to take it out of his mouth. When the shot cuts, the cigarette is far away from his mouth and is suddenly putting it out in an ash tray. (00:10:45)
Continuity mistake: When Jen regains consciousness after being impaled on the tree branch, blood is dripping out of her mouth, onto her nose and off her face. Part way into the scene, the blood has has stopped and her teeth are completely clean. Then a few seconds after that, blood is dripping out of her mouth again. (00:32:05)
