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.
Trivia: Leatherface is based on the killer Edward Gein, who in reality wore his victims faces as masks. He also did some really freaky things with the rest of their bodies, including: a belt made of nipples, chairs with human bones for its legs, a skull top for a soup bowl, etc. The police also found a half eaten heart on a plate, and a nude, decapitated, and gutted body hanging upside down on a meathook in his barn.
Trivia: During the making of the film, the chainsaw they used started up on the first pull every time Gunnar Hanson used it.
