Stories by sci-fi writer Isaac Asimov provide the inspiration for this futuristic action thriller set in Chicago in the year 2035 when robots have been fully integrated into society, occupying the positions of trusted servant and menial worker. Asimov's laws of robotics state that a robot may not allow a human to come to harm. When a top scientist from the US Robotics corporation turns up dead, Detective Del Spooner (Will Smith) suspects the involvement of a prototype that may not be bound by the laws that govern its brethren. Smith gives a charismatic performance in a blockbuster that succeeds chiefly because of the use of CGI - the robots are seamlessly blended into the human environment. As a meditation on whether robots are capable of human emotions, this may not delve as deeply as AI: Artificial Intelligence or Blade Runner, but director Alex Proyas keeps the action racing along with enough invention and thrills to make this well worth the ride.

In 2035, where robots are commonplace and abide by the three laws of robotics, a technophobic cop investigates an apparent suicide. Suspecting that a robot may be responsible for the death, his investigation leads him to believe that humanity may be in danger.
