- Banned In China: This film was predictably banned on about half of Europe for about 20 years following its release. Now it has been unbanned pretty much everywhere.
- Dueling Works: With Fellini's Casanova, which was also released in Italy in 1976. Both are Italian films that explore debauchery as Central Theme, and both are based on the writings of a famous libertine figure of the 18th century — The 120 Days of Sodom by the Marquis de Sade on one hand, and Giacomo Casanova's autobiography on the other. Salò goes full throttle and Up to Eleven with the debauchery/depravity, while Fellini's Casanova is made of Lewd Lust, Chaste Sex and Sexy Discretion Shots. Also, both films were produced by Alberto Grimaldi.
- Hostility on the Set: Suprisingly enough, this was completely averted. French actress Hélène Surgère described the atmosphere on set as fun-loving, jovial, and immature despite the nasty content of the film. Everyone got along very well and there were no arguments or fights at any point during filming; with the majority of the cast using it as an excuse to goof off and play childish pranks on each other. Several of the actors later stated how shocked they were by the finished product, as they had so much fun on set they failed to realise just how dark and horrifying the film actually was.
- Posthumous Credit: Pier Paolo Pasolini was murdered before the film was released.
