Charismatic Korean star Choi Min-sik found international fame as a man bent on revenge in Park Chan-wook's Oldboy. In director Kim Jee-woon's wildly violent, genre-pushing vengeance pic (I Saw the Devil), Choi goes to town as the embodiment of murdering, torturing evil; Lee Byung-hun plays the equally mono-minded special agent seeking maniacal revenge for the death of his pregnant fiancée. Somewhere in all the blood (sickening realism is a selling point), a question is posed: When does the one fighting a monster become a monster himself?
