|“||The perfect knight. Is that what you think you are? Is it?!||„|
|~ Guy to Balian of Ibelin|
Guy is the husband of Princess Sibylla and step-father of Prince Baldwin. He has a strong influence in the court of Jerusalem due to being the brother-in-law of the king, Baldwin IV, though the two hate each other. During one of his ventures, Guy meets Godfrey of Ibelin and his illegitimate son, Balian (the film's protagonist). He mocks them, but they are not impressed, with Godfrey coldly stating that he is glad that Guy is too old to be one of his illegitimate children.
Later, Guy meets Balian in Jerusalem and mocks him for his low birth, while Sibylla (whom he is unfaithful to) becomes attracted to Balian and begins a love affair with him, something Guy is all too aware of. During this time, he teams up with Raynald of Châtillon and attacks several Saracen caravans, getting away with it since there are no credible witnesses. Eventually, this attracts the wrath of Saladin, but Guy is confident that the Crusaders will triumph.
After Baldwin dies, Guy's son becomes king, but he is eventually poisoned by his mother as a mercy killing since he suffers from leprosy, and Guy bullies her into making him the next king of Jerusalem. He orders Raynald to provoke a war with Saladin, which he does by raiding another Saracen caravan and raping and killing Saladin's sister. When a Saracen messenger comes to Jerusalem demanding the return of her body and the severed heads of those responsible for her death, Guy kills him and musters an army of Crusaders to attack Saladin. He also sends assassins to kill Balian at Raynald's insistence, but Balian survives and (possibly unaware of Guy's involvement in the attempt on his life) warns Guy not to leave Jerusalem with the bulk of his army. Guy ignores Balian's advice and marches out of Jerusalem with his army, confident that he will win.
Unfortunately, Guy foolishly leads his army through the desert for several days with rapidly dwindling supplies and no nearby water source, and they all quickly begin to suffer from thirst and the blistering heat. When they finally meet the Saracens at the Horns of Hattin, the exhausted Crusaders are annihilated. Guy and Raynald are captured. Saladin gives Guy, who has notably lost his previously arrogant demeanor, a goblet of iced water to quench his thirst, but Guy gives it to Raynald. Saladin brutally kills Raynald while Guy looks away in silent horror, but spares Guy because "a king does not kill a king." When Saladin's army arrives at Jerusalem, it is revealed that Guy has been stripped naked and is paraded in front of the Saracen army on a donkey.
After Balian negotiates the city's surrender to Saladin, Guy is released. His pride badly damaged, Guy approaches Balian and, in a surprising display of honor, gives him a sword and challenges him to a duel. Despite wielding two swords and showing great swordsmanship skill, Guy is ultimately defeated. He tries to goad Balian into killing him, but Balian spares the disgraced former king, telling him to "rise a knight." He then leaves a frustrated Guy to ponder his words, taking Sibylla with him.
- The film's depiction of Guy is extremely inaccurate:
- The real Guy was not overly arrogant or evil; he was moderate, but ultimately weak-willed and easily manipulated by his ministers, especially Raynald, whom he detested but whose support he desperately needed.
- The real Guy apparently had a good relationship with Sybilla, as she willingly chose him to be the king of Jerusalem after their son died.
- In fact, the real Sybilla was even more fanatical than he was.
