Continuity mistake: When Richard is explaining the plan to Stan and Dimitri after pushing Jen off the cliff, whilst he says "Understood?" to Stan, a light breeze can be seen blowing Stan's shirt collar. When the shot cuts, the breeze is a lot heavier and Stan's shirt collar is moving a lot more. (00:28:23)
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)
Continuity mistake: When Jen is impaled on the branch and is trying to light the tree on fire, a tear can be seen in her shirt, right next to her shoulder. There is one shot where the tear disappears before reappearing again in the following shot. (00:33:35)
Visible crew/equipment: Just after Jen has broken free of the tree branch and hears vehicles approaching, it cuts to a shot of a driving SUV shown from the side. In the shot, a camera and a vehicle used to position the camera can be seen reflected on the SUV. (00:34:40)
Visible crew/equipment: When Richard, Stan and Dimitri drive up to the cliff to find Jen, in the shot of the camera panning alongside the SUV, a car can be seen reflected on it. The only other vehicles that are present in the scene are the four wheeler and the motorcycle, so the car shown in the reflection most likely belongs to a member of the crew. (00:34:50)
Continuity mistake: When Richard, Stan and Dimitri return to the cliffside to retrieve Jen's body, there is a shot of the three shown from below the cliff looking up at them where Richard and Stan are standing side by side and Dimitri is standing a couple feet from them. When the shot cuts to a different angle, all three are standing side by side. (00:36:10)
Visible crew/equipment: When Richard, Stan and Dimitri leave the cliffside to search for Jen, there is a shot of the camera panning across the side of the SUV and the camera crew can be seen reflected on it. The reflection of the camera crew can also be seen when the SUV begins to start driving. (00:37:10)
Continuity mistake: When Richard finds the blood trail at the bottom of the cliffside wall, he points his flashlight at it and begins to point it upwards. In the first shot, he is shown holding the flash light with his left hand near the top, but when the shot cuts, he is suddenly holding it in his right hand near the middle. (00:38:15)
Continuity mistake: When Richard realises Jen was standing against the cliffside wall, Dimitri begins to notice a trail of blood. When he begins to approach it, he is holding a flash light in his right hand, but in the next shot, he is suddenly holding it in his left hand. (00:38:25)
Revealing mistake: When Richard, Stan, and Dimitri are driving through the desert to follow Jen through the blood trail she left behind, tyre marks can be seen on the sand, presumably from previous takes. (00:38:50)
Revealing mistake: When Jen gets out of the lake after Dimitri drives past in the four-wheeler, in the shot of her crawling onto the sand, there are markings on the ground that imply someone had already crawled there, presumably from previous takes. (00:43:05)
Continuity mistake: When Jen is pointing the shotgun at Dimitri, there is a light from the four-wheeler cast on her face. In the shot of her pulling the trigger, the lighting is relatively dim. The shot then cuts to Dimitri, back when it cuts back to Jen, the lighting is a lot brighter. (00:44:30)
Revealing mistake: When Dimitri pushes Jen to the ground after she tries to shoot him, in the shot after she lands on the ground, a pair of trousers can be seen on her legs. Jen is not supposed to be wearing trousers in this scene, so these are presumably protective trousers used for the stunt. (00:44:35)
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: 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: 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 Jen opens the locket to get the peyote, in the close-up shot of the locket opening, the peyote falls out while still holding onto the locket. In the next shot, she isn't holding onto the locket. (00:52:05)
