"I'm not an axe murderer!" mutters drifter Peter to the divorced waitress (Ashley Judd) who's rashly invited him back to her dingy motel room. So begins Bug, an unsettling psychological drama that gradually reveals Michael Shannon's character to be something far worse: a psychopathic ex-soldier convinced he's got military super-nits crawling all over him. Revealing its stage roots at every turn, William Friedkin's virtual two-hander succeeds as a visceral acting showcase before disintegrating into an overwrought orgy of repellent body horror.
"I haven't been to bed with a woman in a long time," says Shannon to Judd's Agnes. "But I think I could go to bed with you!" Stalked by a bullying ex-husband (Harry Connick Jr) and haunted by the child she mislaid years earlier, this stumbling admission is all the encouragement she needs to let this screwball into her bed, life and home. Affection turns to unease, though, as the extent of his derangement becomes clear and her humble abode is turned into an apocalyptic cell, wallpapered with tin foil and festooned with ultraviolet bug zappers.
"MURDER, ARSON AND SUICIDE"
Insects aside, Friedkin skilfully captures the claustrophobic interplay between his two leads and serves up some nasty surprises en route (if the scene where Judd digs an imaginary aphid out of her arm doesn't turn your stomach, Shannon's DIY dentistry undoubtedly will). Eventually, though, Tracy Letts' script - adapted from his own off-Broadway play - scuttles away from him, a climactic onslaught of murder, arson and suicide proving too inflammable for even this director to handle.
Bug is out in the UK on 9th November 2007.
