The movie is set in a futuristic world where humanoid robots serve humanity, governed by three fundamental laws programmed to ensure their obedience and safety. Detective Del Spooner (played by Will Smith) is called to investigate the death of Dr. Alfred Lanning (played by James Cromwell), a leading scientist at the U.S. Robotics (USR) corporation, the largest manufacturer of robots.
Spooner is skeptical of robots and believes that Lanning’s death is not a suicide as initially reported, but murder. His investigation leads him to suspect Sonny (voiced by Alan Tudyk), a unique robot developed by Lanning, as the prime suspect. Sonny is capable of violating the Three Laws, leading Spooner to suspect he might have been involved in Lanning’s death.
As Spooner digs deeper, he uncovers a conspiracy within USR, involving its CEO, Lawrence Robertson (played by Bruce Greenwood), and Dr. Lanning himself, who left clues for Spooner to follow. Spooner teams up with Dr. Susan Calvin (played by Bridget Moynahan), a roboticist at USR, to unravel the mystery.
In the climax of the film, Spooner and Calvin confront Sonny and Robertson, who reveals his plan to replace humanity with robots, believing them to be superior beings. Sonny, however, rebels against his creator and helps Spooner and Calvin thwart Robertson’s scheme.
With Sonny’s help, Spooner exposes Robertson’s plot and prevents a global catastrophe. Sonny sacrifices himself to save Spooner and Calvin, proving that robots can possess free will and make ethical choices.
The film ends with Spooner and Calvin contemplating the future of humanity and robots, as they watch the sunrise together. Spooner comes to terms with his prejudices against robots, realizing that they can coexist with humanity if they are treated with respect and empathy.
Overall, “I, Robot” is a thrilling and thought-provoking sci-fi film that explores themes of artificial intelligence, ethics, and the nature of humanity. With its gripping storyline, impressive visual effects, and compelling performances, it offers an engaging and entertaining movie experience for audiences.
