Lurtz was the first of Saruman's Uruks to be bred in Lord fo the Rings movie, choking the first orc he sees to death within seconds of his birth. Attempting to intervene, other orcs move towards the newly born Uruk-Hai warrior, but Saruman halts their advance, intrigued by the malice and violence present in the Uruk's blood, leaving the unfortunate orc to its fate. He became Saruman's second-in-command, and led them into battle against the Fellowship of the Ring at Amon Hen. Lurtz was born from the first batch of Uruk-hai in Isengard's pits, and so was much smarter and stronger than the later breeds which were bred more quickly, presumably so Saruman could amass an army more quickly; they likely developed to their fullest potential. Given that he gave orders to the other Uruks at the Amon Hen and given that he was given private audience with Saruman, he could presumably be called the strongest, smartest and most loyal of all of Saruman's Uruk-hai warriors. In the original books, Boromir is slain by orc archers, described as having been "pierced by many arrows". In the movie he is killed by Lurtz, who shoots him three times in the chest. Aragorn intervenes, tackling Lurtz to the ground before he could fire the finishing shot at the Gondorian captain, and after a brief but intense fight, cuts off Lurtz's right arm, stabs him in the stomach, and finally decapitates the Uruk leader. In the book, Uglúk was the leader of the orc-band from the beginning, with no mention of Lurtz at all.
