The original director's cut featured scenes of graphic violence and simulated sex, though producer Bob Guccioni inserted hardcore sex sequences against the wishes of the director and the distinguished cast (which included Malcolm McDowell and John Gielgud). Brass, director of exploitation classics such as Salon Kitty, later disowned the film, and it has been heavily censored around the world.
Explicit imagery is rarely permitted by Thailand's film ratings board: Insects In The Backyard and This Area Is Under Quarantine were banned for this reason. (However, film-festival screenings, such as Anatomy Of Hell, Serbis, Otto, Antichrist, and Dogtooth, are generally given more leniency.) There have been covert screenings of Taxidermia, Reincarnate, and The Terrorists, all of which are extremely graphic; presumably the forthcoming Caligula Night screening is similarly unauthorised.
