Revealing: After the crazy man cuts his own hand, he laughs and waves the knife. Watch carefully and you can see the hose behind the blade the blood came through.

Other: In the opening narration, the word "chainsaw" is spelt incorrectly, as two words instead of just one.

Continuity: After the hitch-hiker smears blood from his hand all over the side of the teenagers van, in the very next shot as we see the van riding away down the road, the blood has disappeared from the side.

Continuity: As the teenagers pull up into the gas station, look at the position of the gas pumps hose and its shadow. In the next shot the gas pumps shadow has vanished and the gas pumps hose is positioned differently.

Continuity: When the group of teenagers pull up at the gas station, watch the door of the gas station closely; a red 'open' sign appears on the door after they pull up, and then vanishes and appears once again.

Continuity: When the group of teenagers pick up the hitch-hiker, he goes crazy and cuts Franklin's arm, so they throw him out. As they throw him out the van-door windows are shut. In the following inside shots they're open.

Continuity: When Leatherface grabs Pam you can see him carry her in the door twice during the shots.

Revealing: The position of the hitch-hiker, in relation to the lorry, as it hits him, changes between shots. Also, the hitch-hiker is an obvious dummy as he is hit; you can see the fake limb attachment on his arm.

Continuity: When the man at the gas station washes the teenagers van, the floor around the front of the van is totally wet after he finishes. But as the teenagers pull away the area around the front of the van is now dry.

Continuity: After Sally has run back to the service station for refuge from Leatherface, there is a broom by the door, which changes position a couple of times during the scene.

Continuity: At the end of the film Leatherface takes a socket wrench to the face and falls down into a roadside ditch getting his clothes rather dirty in the process. Moments later, when he's doing his macabre chainsaw dance, his clothes are all nice and clean again.

Continuity: In the scene where the dad comes home, Leatherface is wearing a man's face. Then, only a few seconds later when he walks out of the kitchen he is wearing a woman's face, with makeup on it. This occured due to a scene cut out of the movie. It shows Leatherface taking off the man's face and putting on a woman's face and applying makeup to it.

Revealing: When Leatherface is cutting up Kirk while Pam is on a meathook behind him, he cuts Kirk with the chainsaw twice, but when he lifts it up there is no blood on it.

Continuity: When Sally escapes from the Leatherface family in the dining room, she runs and jumps through a window, and as she lands shards of glass land all about her. In the next shot as she gets up they're gone.

Continuity: When Franklin is rolling down the hill he falls off the wheelchair and it begins to roll. When it cuts the chair is coming down nice and easily on its wheels.

Revealing: Toward the end of the movie, when Sally escapes from the Leatherface family in the dining room, she runs and jumps through a window. As she does, it is blatantly a stunt double; note the curly blonde wig.
