Goofs

In the meat house Chrissie hides in the blood pool, but when she is driving away she is clean.

When Leatherface goes up the stairs to help Sheriff Hoyt, he grabs his chainsaw. When the film cuts to the next shot of him opening and coming through the door, the chainsaw is gone.

At the very end of the movie when the car hits the Texas trooper and the guy he pulled over, as the car comes to a stop the bodies are nowhere near the centerline of the highway. As the killer begins to walk away the bodies are closer to the centerline. Then on the last shot of the accident as the killer walks away one of the bodies is completely over the centerline and directly in the middle of the highway.

During Eric's plastic-wrap suffocation, his hands go from being tied at the ends of the crossbar to together and back again, as evidenced by his arms spread wide or close to his ears.

When Bailey is tied under the kitchen table "mother" starts to wipe the blood off her face. The camera the focuses on "mother" as she sing and cuts back to Bailey, and her face is bloody again.

When Dean tries to escape he gets his foot trapped in a bear trap, which would have broken his ankle, but when he goes to help Chrissie in the meat factory he is running on it.

The Texas license plates on the kids' 4x4 have, what appears to be, a month and year validation sticker on either side of the state name. Texas didn't start using such stickers until 1975. The plates should read 19 Texas 69, all indented.

When the 4WD they were driving near the start flips over, just before it gets towed away, you can see the floor automatic transmission lever is in 'park'. when the camera looks out the front window at the old man and tow truck, you can see the shift lever on the steering column in "park" as well.

The slim design of the chainsaw Leatherface is using would not have been around in 1969. The models of that time period had considerably more bulky engines. The one he had started appearing in the mid '80s.

The song "Vehicle" by Ides of March, was not released until 1970, although the film is set in 1969.

Though the film is set in 1969, the soundtrack features songs that were not released until after 1969. Free's hit song "All Right Now" plays on the radio while introducing Chrissy, Dean, Bailey and Eric. The song was not actually released until the summer of 1970.

The flip-flops Chrissie is using by the pool, are made in Brazil, and bear a Brazilian flag. Although the brand is quite old, the model with the flag is recent (mid 90's).

The pistol Holden (the biker) uses is a Smith and Wesson model 586 , 357 mag. That wasn't introduced until the early 1980s. The film is set in 1969.

When Eric and Bailey push the Tea Lady up against the door, it is clearly seen that the door is attached to the chair the Tea Lady is sitting on.

Draft dodgers and military deserters did not go to Mexico, which has an extradition treaty with the United States.

Canada provided asylum for draft dodgers, and Sweden provided asylum for military deserters.

Both the real Sheriff Hoyt and Charlie both refer to Thomas Hewitt/Leatherface as Charlie's nephew. But Luda Mae found and adopted Thomas at birth, making him her son. Charlie repeatedly calls Luda Mae "Mama" which would make Thomas his younger brother.

Dean would not have used the expression of "Hoo-Hah!" in 1969, for American military forces didn't begin saying that word until about half a century later.
