Looking for a movie about the military (or intelligence agency) creating an AI system that decides to act on its own. I do not recall the system's primary function.
Near the beginning of the movie, we see the primary operator die in a car crash. His brother (identical twin?) is sent in, possibly to investigate, and discovers that the AI system decided to kill the brother to protect itself, and did so by changing a stop light so that he would get t-boned.
It would have been between 2000 and 2010, probably pre-2005. I had thought maybe it was a Jake Gyllenhaal movie, but his IMDB page begs to differ.
