I, Robot (stylized as i, ROBOT) is a 2004 American science fiction action film directed by Alex Proyas, from a screenplay by Jeff Vintar and Akiva Goldsman. It stars Will Smith, Bridget Moynahan, Bruce Greenwood, James Cromwell, and Alan Tudyk. The film is named after Isaac Asimov's 1950 short-story collection and incorporates Asimov's three laws of robotics and several characters, though it is not a direct adaptation.

Plot

In the year 2035, humanoid robots serve humanity, which is protected by the Three Laws of Robotics. Del Spooner is a homicide detective in the Chicago Police Department who hates and distrusts robots after one rescued him from a car crash while allowing a 12-year-old girl to drown—based purely on cold logic and odds of survival. When Dr. Alfred Lanning, co-founder of U.S. Robotics (USR), falls to his death from his lab office window, a message he left behind requests Spooner be assigned to the case, despite police declaring the death a suicide. Spooner is skeptical, and CEO Lawrence Robertson, Lanning's business partner, reluctantly allows him to investigate.
