The Texas Chainsaw Massacre is a series of horror films which depict people meeting their ends at the hands of an Ax Crazy family in Texas, with the chainsaw-toting man known as Leatherface being the prominent deathdealer.The films produced to date:
Cool Mask: More "fear inspiring mask of madness" than cool.
Corrupt Hick: Leatherface and his family. They are a Big Screwed-Up Family who are inbred, murdering, cannibals. At least one source implies that other people in the community know about the family's business, and will cover for them if an outsider tries to turn to them for help. Even though Texas is outside of Appalachia and the Ozarks, the community is supposed to be made up of hillbillies.
Although it's probably less a matter of the locals wanting to cover up the depredations of the Hewitts because "they're one of us" or anything like that, and more a matter of grim survival. The locals turn a blind eye to the Hewitts slaughtering travelers and outsiders who won't be missed, and in return, they don't need to worry about their own loved ones (or themselves) being hacked up, brained, chainsawed or ground into chili.
Doomed by Canon: Any characters from the remake's prequel, and any from the comics set before the remake.
Subverted in the comic The Grind. The main character escapes and survives, but is framed for the murders of her friends by the Hewitts, and is stuck in an insane asylum, where she spends her days freaking out and ranting about the inbred hicks who killed everyone.
Dramatic Unmask: Averted in TCM III, and the remake (where the unmasking isn't dramatic, Leatherface just takes it off while making a new one).
The End... Or Is It?: Every film (except TCM 2, probably) ends with Leatherface and a few relatives still alive. TCM III is the straightest example.
Impersonating an Officer: Sheriff Winston Hoyt was originally Charlie Hewitt, Jr. He killed the real sheriff and stole his identity and car.
It Works Better with Bullets: There's a scene in the remake where the sadistic Sheriff Hoyt forces Morgan into sticking a gun in his mouth, under the pretense of reenacting a suicide committed earlier in the film; continually goading the obviously terrified Morgan (who doesn't know if the gun is loaded or not) into pulling the trigger Hoyt arrests him under the charge of attempted murder when Morgan tries to shoot him with the gun. Its implicated this was Hoyt's plan all along.
Meaningful Name: Leatherface's Cannibal Clan are known as the Sawyers in the original series and the Hewitts in the remake series. The former name basically means "those who saw things apart", while the latter means "cut it apart".
Mummies at the Dinner Table: The family have habit of treating dead relatives as if they're still alive, going as far as turning Nubbins's corpse into a crude puppet in TCM 2.
My Car Hates Me: Most of the time its due to them being trashed by the villains, not some malfunction.
Punch Clock Villain: Leatherface shows no sadism and kills only for food. Justified in that he is shown as mentally handicapped. His family though takes sadistic pleasure in tormenting and killing the victims. Especially Sheriff Hoyt in the remake series.
Recycled Premise: Aside from 2, all the films in the franchise recycle the plot of the first film.
Red Right Hand: Nubbins's facial birthmark, Chop Top's similar birthmark and exposed metal plate, Tinker's Hook Hand, Mama's electronic voice box, Alfredo's speech impediment and heterochromia, and Vilmer's bionic leg.
The Quisling: In the remake series the family abduct young children and raise them as their own.
The Savage South: Because the only locals who really get any characterization are all part of Leatherface's family, it gives an impression that everyone but the "outsider" is OK with the events in these films.
In Texas Chainsaw 3D, though, it's established that the townsfolk murdered the Sawyer clan after their killing spree in the first film.
Attempted Rape: The Avatar Press comics apparently liked this trope. In Special a serial rapist tries to have his way with the main character, but is killed mid-attempt when Leatherface impales him through the back with his chainsaw. In The Grind, the main character is tied to a bed so Monty can have his way with her, but she gets an arm loose, punches him unconscious, and escapes.
Town with a Dark Secret: The Wildstorm comics which act as a sequel to the remake reveal that the townspeople are fully aware of Leatherface and his family's murderous and cannibalistic tendencies, but don't do anything for fear of retribution.
