What could have been a reasonably interesting thriller literally goes to pieces in last third, until the brain seems the most salient part missing. Pic was inspired by a novel [Choice Cuts, adapted by Patricia Herskovic and Joyce Taylor] by French authors Thomas Narcejac and Pierre Boileau, who wrote the novel that provided the basis for Vertigo. Hitchcock and others reportedly grappled with adapting this book.
Jeff Fahey plays a criminal psychologist who loses his arm in a car accident, only to have it replaced by a doctor (Lindsay Duncan) perfecting a new limb-grafting procedure. The psychologist is told that the new limb belonged to a serial killer, prompting him to wonder if the murderer’s arm might be invading his own soul.
He even seeks out other donor recipients (Brad Dourif and Peter Murnik), who are initially unconcerned or unaware of any ill effects. Then, suddenly, the narrative hurriedly kicks into a slasher mode, replete with car chases, dismemberment and unintentional, if rather vulgar, hilarity.
