(FILM) The Austrian director Michael Haneke, best known for the shock-masochism of his 2001 film, The Piano Teacher, now gives audiences the far subtler and more politically engaged Caché (which won him the Best Director prize at Cannes). Unnerving surveillance videotapes keep showing up at the home of a Paris couple and the road leading back to the culprit is cluttered with bloody chicken heads, imperialist xenophobia, and red herrings—if you've heard that the final scene solves the mystery, you've been misinformed.
