Continuity mistake: Between shots from when Vilmer leaves the kitchen (and throws the big broken part of door at the wall) and then when W.E leaves the kitchen seconds later, the trash over the hallway floor and the kitchen floor (cardboard, wood, paper) drastically differs position and location, and additional trash appears too. (00:50:50)
Continuity mistake: The cut above Jenny's left eye differs in various scenes. For instance, in the kitchen scene it is at least a centimetre above her eyebrow, but then in the scene where Vilmer holds the knife up to her throat it is right above her eyebrow. (00:51:20 - 00:54:30)
Visible crew/equipment: When Jenny crawls across her car, you can clearly see the black kneepads she is wearing. (00:58:50)
Audio problem: When Vilmer says "Welcome to mmmyyy world." his mouth says "Welcome to mmmyyy home." (01:02:20)
Continuity mistake: After Jenny yells "It's fucking pathetic" to Vilmer, Vilmer gets mad and throws a book across the room, and then grabs Darla and throws her to the floor. The chair next to Darla has three bones on the top of it as 'decoration.' As Vilmer grabs her and throws her down, the tall white bone on top of the chair falls to the floor. But in the next shot as Vilmer whacks W.E with a hammer, the bone is back on the chair. (01:05:35)
Continuity mistake: When Vilmer lights the girl's back on fire as she's passed out at the table, she gets up and starts stumbling towards a wall covered in keys. As she stands up, there is no visible fire on her back. In the next shot as she is up against the wall, her back is on fire again. (01:06:25)
Visible crew/equipment: When Leatherface is chasing Jenny, she gets into a couple's caravan. After Leatherface tries to get in, it cuts to an exterior shot and as Leatherface is running along with the caravan, in the window behind him you can see a crewmember with a cap on, running behind him off-screen. (01:15:20)
Revealing mistake: In the end when Jenny is sitting in a chair at the hospital with a doctor, in the glass screen behind the doctor you can see the reflection of the gurney which will be pushed on-screen in a few seconds. The doctor is obviously waiting with the gurney for his cue to come past. (01:19:10)
Factual error: In the closing credits Matthew McConaughey's name is misspelt "Matthew McConnaughey." (01:20:00)
Continuity mistake: In the scene when Vilmer is standing on Darla's throat, we see her laying across the floor horizontally away from him, but in the next shot, we see that she is laying vertically to him.
