Continuity mistake: 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. (00:16:30)

The Texas Chainsaw Massacre (1974)
Ending / spoiler
Directed by: Tobe Hooper
Starring: Edwin Neal, Allen Danziger, Marilyn Burns, Paul A. Partain, William Vail
All of the teenagers are killed and Sally is tied up and terrorized by the cannibal family. The grandpa tries to kill her with a sledgehammer but only wounds her because he is too weak. Sally barely escapes the house and the brothers chase her onto the road. The Hitchhiker brother is run over by a truck and Leatherface accidentally cuts into his own leg with the saw. Sally escapes for good in the back of a passing pick-up. (We don't know if the truck driver who stopped to help Sally survives.)

Drayton: Look what your brother did to the door! Ain't he got no pride in his home?
Trivia: Many praise the movie for being well acted with such a low budget. Two performers that are singled out are Marilyn Burns and Paul Partain, who play Sally and Franklyn. In the scenes where they squabble, the acting is quite impressive. But was it really acting? The two performers, in reality, could not stand each other.
Question: In the trivia it says that the name Leatherface is only said once or twice. Well, I can't recall the name being used at all. What scenes were the name used?
Answer: At the dinner table scene when the hitchhiker is arguing with the old man, he says "me and Leatherface do all the work." There's a lot of shouting going on so it's easy to miss.





Answer: The name "Leatherface" is used in the scene set in the hotel, and the waterfall scene. The grandmother says "leatherface" right after she says "Maryana, crank up the chain saw" in the waterfall scene. She actually says it in a whispering tone, so you have to turn the volume up to the max.
I think you're referring to either a remake or sequel. In this film (the original made in 1974), there is no living grandmother that speaks, scene set at a hotel, character named Maryana, or a waterfall scene.
