Working in the finest tradition of brain-dead blockbusters, director D.J. Caruso (Disturbia) and executive producer Steven Spielberg take a script riddled with absurdities and throw millions and millions of dollars at it. Two Chicagoans who don't know each other (Shia LaBeouf and Michelle Monaghan) are coerced into carrying out a terrorism plot by a mysterious and omnipotent organization that communicates with them by cell phones, manipulates their movements with split-second timing, and controls almost every electrical device in their path, from security cameras to traffic lights to the scrolling LED screen in a travel office window. Caruso and Spielberg probably thought they were reviving the paranoid style of 70s political thrillers, but their story is so implausible it barely provokes a tremor. With Billy Bob Thornton, Michael Chiklis, Rosario Dawson, and Anthony Mackie. PG-13.
