Continuity mistake: When Chris talks to the cop and then the cop gets shot with an arrow, Chris runs into the truck and the man shoots another arrow. So altogether he shoots two times. The first one is in the cop's eye, so how come when he shoots the second through the truck window, there are now two arrows there, not one. He only fired two arrows and we see three. (01:04:20)
Plot hole: The fearless trio is in the watch tower when the hillbillies set fire to it. Realizing their fate if they stay, the three then jump out the window and onto nearby tree branches in order to escape the blaze. After escaping the towering inferno, it seems that the fire dies immediately. These three don't go far after jumping and are in the trees for some time. Shouldn't there be a great glow and lots of noise and smoke from the fire as the watch tower burns down? (00:53:45 - 00:56:00)
Continuity mistake: In the scene where Carly, Scott, Chris and Jessie are approaching the house in the woods, the shot from the back shows Jessie crossing her arms and leaving them there, and Scott behind Carly, but a shot from the front shows Jessie's arms down by her side, and Scott holding Carly. (00:23:00)
Continuity mistake: Towards the beginning of the film, as Jeremy Sisto walks down the road, he's wearing a flower necklace in the scene before his girlfriend has picked the flower for him. In the subsequent scene when she picks it, he's not wearing it.
Suggested correction: It's not the same flower, actually. She picked that one when he already had one on his necklace—it's just hidden in this scene.
Continuity mistake: When Chris is hiding under the bed with Eliza Dushku, after the mountain-men drops the corpse, we see blood flowing towards the left hand, that is under the Chris's chin. In the next shot, the hand is the right one and after that it is the left one again. (00:31:49)
Continuity mistake: When Rich and Hailey are rock climbing, Rich reaches the top and is then killed and blood drops onto Hailey's face. It is in droplets, then Hailey wipes it, so it smears across her face, then it changes to a droplets again, then to smears, and the location, shape and size of the drop/smears differs too. (00:02:10)
Continuity mistake: When they find the watch tower, Chris tosses aside the branch he was using as a crutch, so that he can climb up the ladder. After they've been spotted, when one of the mountain men is trying to come through the trap door, watch closely. After they block it off, Chris grabs the branch to use as a weapon.
Continuity mistake: At the beginning of the film when Chris is on the phone in his car, he loses the signal; watch his hand on the phone, it changes between shots. (00:07:55)
Continuity mistake: Chris and Jesse, and Carly and Scott are walking along and Chris is trying to get a signal on his phone. Then when the shots changes, Jesse and Chris have swapped sides. (00:18:40)
Continuity mistake: In the opening scene of the film when we see the male climber almost reaching the top of the cliff. If you look on the side of the cliff, there is some kind of metal device/climbing equipment. This object moves between shots from being about two feet away to the right from the male climbers hand, to a few inches when the climber reaches for his last grip on the rockface. (00:01:05)
Continuity mistake: When Carly and her boyfriend are walking on the road, they stop to talk, and the other characters continue on. Seconds later Carly and her boyfriend spot a fire at the side of the road, and now they are ahead of the other two characters.
Continuity mistake: After the watch tower scene when Eliza is walking on the branches there are a few close ups of her feet trying to keep her balance and her boots are completely spotless. Later when she is tied up on the bed her tank top is also very white and clean.
Visible crew/equipment: When Scott falls after getting hit by the three arrows, you can clearly see a long tube leading all the way up his leg which pumps the fake blood up to his shirt. (00:41:25)
Continuity mistake: Chris walks up to one of the drivers of the truck to ask what's going on, and when the driver speaks to Chris, the distance between the driver's head and his arm, changes between shots. (00:06:50)
Continuity mistake: When Francine gets out of Chris's car, and starts shouting "Evan", between shots she brings her arm down to her side twice. (00:18:20)
Continuity mistake: When Chris is driving towards the shortcut, in one shot Chris is driving towards an opening in the bushes and trees, yet in the following shot, if you look out the windows it's back to bushes and trees, with no openings. (00:10:25)
Continuity mistake: Close to the beginning when the guy and girl stay behind at the 4x4, in one shot you can see that the girl has both legs up, in the following shot one is up. (00:15:05)
Continuity mistake: At the beginning when we see Chris at the gas station, in one of the shots the man sitting in the chair puts his drink to his mouth, yet in the following shot we see him getting to his feet. (00:09:30)
Continuity mistake: Just after Carly, Scott, Jessie and Chris have left the house in the woods after waking up the Hannibals, the four of them proceed to run up a steep hill. When Carly and Scott begin to climb the hill there is no large tree stump on the ground, yet in all following shots one has appeared to help them climb up. (00:35:45)
Continuity mistake: When Chris and the others are talking outside the house in the woods, Scott starts talking about West Virginia or something, and in one shot he raises his right hand to his head, and in the following shot he has his left hand to his head. (00:23:50)
