** The film was banned in Finland for over twenty years.
** It was also banned in the UK for having [[Main/InsaneTrollLogic "Chain Saw" in the title]]. It was never on the official VideoNasties list, though it has at times been reported as such.
** Banned in Germany for 25 years, save for a heavily censored version that lacked 12 minutes of film. The ban was lifted in 2012 after a three-year lawsuit carried on by the new rights holder.
** Italian, ''Non aprite quella porta'' (''Don't Open That Door'').
** Japanese, 悪魔のいけにえ (''Akuma no Ikenie''), ''Devil's Sacrifice''.
* DuelingMovies: With ''Deranged: Confessions of a Necrophile'', another 1974 movie that was inspired by the [[https://en.wikipedia.org/wiki/Ed_Gein Ed Gein case]] from the 1950s.
** For the scene where Pam was hung up on a meathook, Teri [=McMinn=] was held there by nylon rope tied between her legs. The position ending up being ''extremely'' painful for her, and the screaming Pam does in the scene is genuine pain on the part of Teri.
** When Leatherface cuts Sally's finger so Grandpa can drink her blood, the device attached to the knife that was ''supposed'' to squirt stage blood broke. Gunnar Hansen, already breaking down from having to film the scene (see SanitySlippage), proceeded to cut Marilyn Burns' finger open for real in order to get the scene done.
** Most of the actors didn't actually meet Gunnar Hansen, let alone see him in costume, before their first (which is also usually their last) scene with him. Additionally, there was only one Leatherface outfit and they didn't dare wash it, so Hansen was in the same outfit for weeks in hot Texas weather, making the other actors physically repulsed by his, um, aroma.
*** His smell reportedly got so bad that no one wanted to eat lunch with him, further isolating him from the rest of the cast, even his own "family."
** In real life, Gunnar Hansen was regarded by many as an [[GentleGiant incredibly nice guy]]. While preparing for the role and trying to develop mannerisms for Leatherface, he became a volunteer for a school for special needs kids.
** Gunnar Hansen strongly disliked Paul A. Partain when they worked together on set, because Partain tried to stay in character as the whiny, complaining Franklin during shooting. When he got to know Partain after filming had wrapped, they became close friends.
* NoBudget: As mentioned on the main page, the film only had a budget of $140,000.
* TheRedStapler: [[InvertedTrope Inverted]]. According to Edwin Neal (Nubbins/Hitchhiker), Texas State Troopers actually shook his hand and thanked him for causing crime to drop 18%; apparently the message audiences took away from the movie was "Don't pick up hitchhikers".
* SanitySlippage / TroubledProduction: Happened ''for real'' while filming the infamous dinner scene. The food rotted under the filming lights and created a horrific smell, combined with that scene filming for 27 straight hours in 110 degree Texas weather, actually drove the actors a bit nuts. The DVD commentary has Gunnar Hansen eerily recounting how he genuinely wanted to kill Marilyn Burns for a few seconds after being ordered to by his "brother." Vietnam veteran Edwin Neal (Hitchhiker) even describes it as worse than anything he went through during the war.
* TroubledProduction: Filming went reasonably smoothly for the most part, but its third act seemed to be trying to make up for that.
** First, lead actress Marilyn Burns proved completely unable to convincingly keep ahead of Gunnar Hansen as Leatherface while he was chasing her through the woods, forcing Hansen to run much slower than he actually could, and even resorting in one shot to pointlessly cutting up tree branches to let Burns widen the gap between them. There was also an incident where Hansen slipped on the wet grass and lost his grip on the still-running chainsaw, which flew up in the air and then came down point-first just inches from his head.
** For the scene where Sally's finger is cut for the Grandfather to suck on, the device to spurt fake blood wouldn't work. Thus, what you're watching in that scene is Marilyn Burns ''actually'' getting her finger sliced open. Though they thankfully didn't go as far as to make the guy playing Grandfather suck on her real bleeding finger, and there's a quite noticeable edit before he starts sucking.
** And then came the worst part of all with the climactic dinner scene. All the food on the table quickly rotted under the filming lights, and the room's poor ventilation made the stink even worse, raising it to genuinely health-threatening levels. Several of the actors suffered genuine SanitySlippage and took Tobe Hooper's direction as meaning they really were their characters, not exactly the result you want when most of them were playing cannibalistic murderers. Edwin Neal, who played the Hitchhiker, had just come home from the Vietnam War and described filming this scene as worse than anything the Viet Cong put him through. After it was all over, the rest of the crew were all furious at Hooper and he's said it took years for any of them to cool off.
* UrbanLegends: A persistent urban legend is that the movie's popularity was due to including [[SubliminalSeduction subliminal messages]] telling viewers they loved the film.
* WorkingTitle: ''Stalking Leatherface'' and ''Head Cheese''.
