When Jenny is in the car with Vilmer, there is a radio speaker hanging on a wire next to her. When she says, "What's gonna happen to me," between shots the radio speaker disappears from the end of the wire.
When Darla is at Bud's Pizza Drive-Thru, she gets out the car to go round to the boot and tell Jenny off. As she walks round to the boot, in the backseat window you can see the reflection of arms holding a boom mic.
When Leatherface grabs Heather on the porch, he pulls her towards the door and then rams into the door with Heather in his arms going into the door first. However when it changes to an interior shot of the house, and they come bursting through the door, Leatherface comes in first with his back to the door.
When Leatherface chases Jenny, she locks the front door and then Leatherface uses his chainsaw to break pieces of the door out. However in a reverse shot, some of the door that Leatherface previously broke off is now back intact.
When Barry and Heather are walking along in the woods, as Barry says, "That bitch, she started this whole thing," his collar changes from tucked under his black suit to suddenly being out, between shots.
Darla's window gets smashed by some local boys, and when she flashes them you can see there is some kind of netting in the window which is ripped. In the next shot the netting has vanished from the window.
As Jenny is climbing up a big aerial on the roof, Leatherface swings his chainsaw at the aerial. In shots of him swinging the chainsaw, Jenny has disappeared from the aerial. You can almost see the whole aerial, and she isn't there.
When the motorbike rides by, Jenny runs after it yelling "No, wait." In this shot Jenny has the flashlight in her right hand and the big red rose as part of her prom outfit is on her left breast. But the next shot is obviously flipped, as the torch is now in her left hand and the rose is on her right breast.
When Leatherface gets Heather in the house, he grabs her and drags her down the hallway, as he enters a room, Heather grabs the sides of the doorway, to pull herself away from him. In the shot, you can see the wall to the right of the doorway has a mirror on the wall, nothing else, and on the counter below is a few lone light-bulbs and a coke can. However in the next shot, so many objects appear. There's now meat-hooks, chains and belts hanging on the wall either side of the mirror, and the counter is now covered in canisters, metal barrels and boxes.
Jenny wears a white silk scarf loosely around her neck, as part of her prom outfit. As Leatherface chases her through the muddy river, the scarf falls down her body to her waist. In the next shot though, it's back round her neck. After this, she removes the scarf from her neck and throws it in the river three times between shots.
When Jenny is standing at the open door of Vilmer's truck, asking him where Sean is, she has her left hand resting on the truck door. In the next shot it's her right hand resting on the door, and then her left again in the next shot.
The cut above Jenny's left eye differs in various scenes. For instance, in the kitchen scene it is at least a centimeter above her eyebrow, but then in the scene where Vilmer holds the knife up to her throat it is right above her eyebrow.
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.
W.E. brings a big part of a door into the kitchen and says, "Look at what your brother did to this door," and then he places it down so it leans up against the other door. Then moments later the big section of the door is now lying on the floor. It is leaning back up again a few seconds later.
When Leatherface is chasing Heather, he breaks through the door, and a large portion of the door breaks out and falls to the floor. But in the next shot, the same part of the door that fell out is still broke off, but is now half hanging from the door and then falls off again.
When Jenny jumps through the window, as she lands on the roof she rolls to the side and her legs fly upward. You can clearly see she has protective padded socks on to protect her ankles. She is barefoot in all previous and following shots.
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 crew-member with a cap on, running behind him off-screen.
When Jenny runs to Darla's trailer after being chased by Leatherface, she runs inside and trips, and her dress pulls upward, beautifully revealing the flesh-colored kneepads she's wearing for the stunt.
As Leatherface breaks parts of the front door out with his chainsaw, there are three very large cracks in the door, presumably to help him break the parts of the door out. In all previous shots/scenes, there were no cracks in the same part of the door.
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.
