Law 1: A robot can never harm a human.
Law 2: A robot must obey all human orders unless it conflicts with the first law.
Law 3: A robot must protect itself unless it conflicts with the first two laws.
When I, Robot came out, I heard a lot of criticism, mainly because it wasn’t close to Asimov’s original book. But I was actually really impressed by how good this movie was. (It helps when you have low expectations, I know.) This may be my favorite Will Smith movie, next to “Independence Day.†Not only was it suspenseful and action-packed, but had a great plot with surprising twists as well. My only complaint was that they didn’t delve more into Sonny’s persona, the robot who was self-aware. This was a great character, part of the main theme of the movie. But Detective Spooner (Will Smith) was explored very well, and he brought a great comedic element to the movie.ÂÂ
It’s the year 2035, Spooner, who hates/doesn’t trust robots, is assigned to a case where a robot is implicated in the murder/suicide of the scientist who created these robots. Robots are not supposed to be able to break any of the Three Laws of Robotics, mentioned above. But Spooner’s worst fears come true as the rollout of a new upgrade of robots number a ratio of 1 robot to every 3 humans.  And as it becomes apparent early on, these robots may not always follow the 3 “Laws.”
