This film was screened on Australian TV when I was about 15. It's extremelly violent and psychological, a study in deprivation and pain. I mainly remember Nick Cave's performance (he co-wrote it). He plays a lunatic that get's moved to an already tense prison. His ranting and self-mutilation escalate the other prisoners sense of panic and chaos. Incredible acting and a very realistically frightening film. It's not fun, exciting or most things people look for as a distraction in modern day cinema, but if you're looking for something challenging and thought provoking it's well worth trying to find.
