Filmed in Glasgow and Edinburgh, this dark Scottish comedy follows the misadventures of two men and a woman who advertise for a roommate and wind up with a guy who dies of a drug overdose, leaving behind a suitcase of money. What ensues after they decide to keep the money and get rid of the body determines the rest of the plot, in which the sexual and psychological ambiguity of this heartless trio gets run through a good many changes. Directed by TV veteran Danny Boyle from a script by one Dr. John Hodge, this is a fairly accomplished first featureperky, visually inventive, and unusually nasty, though I suppose a humanist message of some sort lies vaguely at its core. With Christopher Eccleston, Ewan McGregor, Kerry Fox, and Keith Allen. (JR)
