Bound by 3 robotics laws built into each robot, they are allowed to serve but not harm mankind. Will Smith plays detective Del Spooner, a Chicago police detective who distrusts robots because of something that happened in the past. Del is called in on a murder case, where he suspects the culprit may be a robot. As the investigation proceeds he gets involved with the head of U.S. Robotics (Bruce Greenwood) and Psychiatrist Susan Calvin (Bridget Moynahan), who works with the robots to make them more human.

U.S. Robotics just introduced a new line of robots (NS5) so improved they outdate the previous version (NS4). One of these new models is Sonny, who seems more human than the other robots. After an investigation, he runs when questioned about the murder. You will find plenty of funny one-liners here, a lot of great special effects, and a satisfying movie.

The story is loosely based on Isaac Asimov's 50-year-old short story about Robots helping the human race. Sonny is the star robot who takes on a range of human emotions and becomes an intricate part of the story. Alex Proyas who directed "Dark City," and "The Crow"), directs this blockbuster.
