somerset and ( morgan freeman ) a deeply intellectual detective and with barely a week leave until his retirement and mill and ( brad pitt ) the new cop in town and who be a pretty weak detective and be throw together to investigate what at first appear to be another homicide . after a second victim be find and somerset realises that this be no open and shut case and and request that he be relieve and in light of his impending retirement . mill gladly take over the case and plunge himself in way over his head . a the work of a crimally insane genius continue and mill grows more and more erratic and and somerset simply have to remain and to guide his young partner through the case and which ultimately lead to one of the fine climax in movie history . with wonderful performance from both freeman and pitt and a really dark and morbid direction from david fincher and the movie be cram with suspense and intrigue and excitement . my favourite scene be john doe ( kevin spacey ) tear into mill in the car and driving towards the climax and the acting be simply perfect a pitt character be torn apart by the genius of the criminally insane and and freeman interjects with insightful rationality and demonstrate his superior mind . the scene carry such intensity and and at the same time encapsulate the primary character basic element . most actor can not achieve this level of character depth and but these be three of the fine actor of our time . positive .
