As paranoid cop Del Spooner, Will Smith displays both his trademark quips and some impressive pectoral muscles in I, Robot. Only Spooner suspects that the robots that provide the near future with menial labor are going to turn on mankind--he's just not sure how. When a leading roboticist dies suspiciously, Spooner pursues a trail that may prove his suspicions. Don't expect much of a connection to Isaac Asimov's classic science fiction stories; I, Robot, the action movie, isn't prepared for any ruminations on the significance of artificial intelligence. This likable, efficient movie won't break any new ground, but it does have an idea or two to accompany its jolts and thrills, which puts it ahead of most recent action flicks. Also featuring Bridget Moynahan, Bruce Greenwood, and James Cromwell. --Bret Fetzer
