A strong contender for the sickest movie of all time, Ichi The Killer exhibits Miike Takashi's freewheeling visual imagination nonetheless. It's an ultraviolent revenge movie based on a Manga cartoon in which a sinister hypnotist manipulates the timid but unstable Ichi to dispatch various mobsters in horrifically violent fashion by invoking false memories of witnessing an assault. His ultimate target is a mutilated Yakuza played by the excellent Asano Tadanobu, sadistic and masochistic in equal measures, inciting boss and girlfriend to beat him savagely and exacting horribly inventive torture techniques on his enemies. At one stage, when he overdoes it and angers his bosses, he volunteers a "sincere apology" and cuts out his own tongue. He claims everyone is part sadist, part masochist and the director explores this theme with disturbing enthusiasm. This could do the job very nicely as the "therapy" film in A Clockwork Orange.
