Common threads of rage and revenge run through Australian director Rolf de Heer’s previous featureThe Tracker, an avant-garde aboriginal westernand this thriller in which a man comes home to an empty house and watches a video prepared for him by his wife. While extremely unpleasant, Alexandra’s Project (2003) is compulsively watchable, and actors Gary Sweet and Helen Buday both turn in tour de force performances. What begins as a story about a smug and insensitive husband getting his just deserts crosses a line that will have some blanching at the wife’s behavior as well. Like the work of Neil LaBute and David Mamet’s Oleanna, de Heer’s film puts us all on the spot. 103 min. (JR)
