Flicking through the electronic programme guide list of movies to see if there's anything worth recording (you'd be surprised how many "Everyone's seen that" films I never got to - or maybe not), I found this warning in one movie's information note: "Scenes of violence/torture/sex/live octopus ingestion."
Ah well, it certainly helped me decide whether or not to bother. Unlike the occasional warning that a film "contains mild language". Are they imagining people saying "That's no good, I want non-stop swearing tonight"?
