Diane Lane plays FBI agent Jennifer Marsh in this cyber-thriller set in moody Portland. She pursues a psycho killer who created a Web site called www.KillWithMe.com that live-streams video of his victims. The first is a cat with its paws stuck in a glue trap for mice. His next victims are those the killer wishes to punish for their voyeurism by recruiting voyeurs as accomplices. He constructs lethal torture contraptions using sulfuric acid, heat lamps and a roto-tiller. In each case, the victim’s death is caused as more people log on to watch. The killer—who uses “backdoor Trojans” and thinks Fox News and the NSA are in bed together—says the deaths on his site are really caused by the people who know they’re players in the snuff show on their computer screens. Director Gregory Hoblit (“Fracture,” “Frequency,” “Primal Fear”) and writers Robert Fyvolent, Mark Brinker and Allison Burnett package a functional genre exercise with the usual cross-platform moralizing: an exploitive film scolds the exploitive Internet. “Untraceable” puts us in the same spot as the site visitors. We watch on the big screen and feel superior to the watchers on small computer screens. Is there a first-person shooter game that rewards players for killing off the makers of first-person shooter games? With Billy Burke, Colin Hanks and Mary Beth Hurt. 89m. (Bill Stamets)
