Dark thriller starring Diane Lane. Within the FBI is a division dedicated to investigating and prosecuting criminals who commit crimes on the Internet. Two members of this division are Agents Jennifer Marsh (Lane) and Griffin Dowd (Colin Hanks). When an Internet predator begins displaying his brutal murders on his website, it's up to Marsh and her team to track him down before he kills again. Unfortunately, the fate of each of his victims is left in the hands of the public - the more hits his website gets, the quicker his victims die. Untraceable fuses Saw with The Net in a perverse yet moralistic story about a psychopath who broadcasts acts of torture over the internet--all to better reveal the twisted underbelly of the American public, who hasten the victims' deaths simply by looking at the website. FBI agent Jennifer Marsh (, her mature-sexy mojo tamped down but still simmering in the corners of her eyes and the nape of her neck) launches a cyberhunt for the killer, only to find herself and her team caught up in his murderous scheme. It's hard to make tapping on a keyboard and staring at a computer screen exciting, but Untraceable does its best by making Marsh and her cybercrimebusting partner (, King Kong) rattle off cascades of jaunty techno-jargon and do impressive bits of long-distance surveillance. The movie aims for the audience that flocked to see Ashley Judd in thrillers like Kiss the Girls and Double Jeopardy, but it's hard to say if fans of Lane's romantic fare like Under the Tuscan Sun or Must Like Dogs will enjoy the queasy violence. Nonetheless, the cast--including Mary Beth Hurt ( The World According to Garp) as Marsh's mother--does a solid job and the movie clips along at an aggressive pace, maintaining tension throughout. -- Bret Fetzer Synopsis Directed by Gregory Hoblit ( Fracture, Primal Fear), Untraceable follows F.B.I. cybercrimes specialist Jennifer Marsh (Diane Lane) as she attempts to track down a serial killer who brazenly displays his murderous deeds on the internet. Aided by fellow agent Griffin Dowd (Colin Hanks) and local detective Eric Box (Billy Burke), Marsh tenaciously hunts for the elusive criminal but as she closes in on her target, he deviously finds ways to get closer to her, all the while killing his victims in increasingly faster fashion. Untraceable clearly references a number of renowned thrillers, most notably the SAW films, Seven, and Silence of the Lambs. Lane's steely, smart, and beautiful heroine ably anchors the film, which also benefits from its appropriately gloomy Portland, Oregon, backdrop. As with any effective suspense movie, the thrill is in the chase, with the cold-blooded killer proving to be quite adept at disguising his real location, even as his disturbingly popular site remains prominently on the web.
