The "cell phone thriller" is becoming a genre unto itself, and Eagle Eye should be considered a key example of the form. Frankly preposterous but compulsively watchable, this movie puts Shia LaBeouf in a mess of trouble instigated by a mysterious telephone voice. If he doesn't follow orders, dire things will happen--although when he does follow orders, the consequences are pretty dire, anyway. Also being blackmailed is a single mom (Michelle Monaghan) receiving similar phone calls. Why are they being jerked around by the purring female voice, and why is the road leading to Washington, D.C.? Actually, you won't have time to contemplate these questions, because director D.J. Caruso (who guided LaBeouf in Disturbia) keeps the action going at the customary breakneck pace.
