25 Horror Films You Must Watch Before Halloween

15. I Saw The Devil

Kim Ji-woon's savage thriller-horror flick is further proof that nobody does horror quite like the South Koreans. A brutal revenge film in the darkly comical vein of Oldboy, I Saw the Devil follows a secret service agent (Lee Byung-hun) as he tracks down the psychopathic serial killer (Choi Min-sik) who murdered his pregnant fiancee. The results, unsurprisingly, are almost unbearably grim, but Ji-woon imbues his film with just enough gallows humour to balance the tone. Best Moment: It wouldn't be fair to spoil it as so few people have seen the film, but it involves a guillotine, and it's both hilarious and gory.
