Continuity mistake: When Chris and the others are inside the house, Chris goes to turn the music off. He turns the music off with his right hand before the gold amplifier, but in the following shot his hand/arm is over the gold tube coming from the music box to switch it off. (00:24:50)
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 the cannibals drag Francine to the chopping block, she has her shirt on. Next shot her shirt is suddenly off. (00:32:15)
Continuity mistake: When Chris, Jessie, Carly and Scott come out from hiding in the house, Scott comes out the door and Carly puts her hand on his hand, but in the following shot Carly's hand is on Scott's wrist. (00:34:00)
Continuity mistake: Close to the beginning when Chris and the others are creeping slowly out of the house in the woods, Chris puts his hand on the door well above the doorknob, yet in the following shot, his hand is below the doorknob. (00:34:55)
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)
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: When Chris, Jessie and Carly get the truck stuck in the mud and have to continue on foot, Jessie and Carly sit in front of the truck and talk. In this shot Jessie puts her left hand on Carly's neck, but in the following shot it is no longer there, then the shot after it is back on her neck again. (00:44:05)
Continuity mistake: In the middle of the film when we see Chris, Jessie and Carly in the watchtower, the cannibals who are trying to get them pull down on the radio lead, and Jessie and Carly react and step back, when it cuts to Chris, there is a reflection in the glass of the two females with the same reaction. (00:51:55)
Continuity mistake: When Chris, Carly and Jessie are being burned out of the watchtower by the cannibals, Carly breaks a window by throwing a suitcase out of it. When she throws it through, most of the window and window frame smash. Yet in the shot from inside we see the left side of the window intact and the right smashed, a shot from the outside shows most of the window and wooden frames holding the glass in are still there even though we saw most of the glass and frame gone in the shot from inside. (00:52:40)
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: 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)
Continuity mistake: Near the end of the film when Chris is hiding underneath the cops' 4x4, we see one of the cannibals lean down to pick up the 4x4's keys off of the floor. He reaches with his left hand, but a shot from underneath the 4x4 shows the cannibal's right hand instead. (01:05:00)
Plot hole: In the end, the old timer sees the truck approaching and gets up and closes the door and acts as if he's scared. As we learned in part 2, these hillbillies are related to each other. Considering he knows the yellow truck, why does he act afraid? (01:16:15)
Suggested correction: The sequels do not affect the original. Not a valid mistake.
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 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: 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.
Continuity mistake: After the crash the four start walking. While Scott is talking to Carly about eloping, she puts her hands on his shoulders, then puts them down, but in the shots from behind Scott her hands are still on his shoulders. When it cuts back to facing Scott, Carly's hands are down again.
Continuity mistake: When Carly, Jesse, and Chris are walking through the woods, Carly's make-up and hair are all messed up, while Jesse's hair and make-up are neat, and is not sweaty at all.
