Most of the characters in "Kingdom of Heaven" are adapted from historical figures. Professor Hamid Dabashi of Columbia University is the chief academic consultant of the film. In France in the 12th century, the young blacksmith Balian (Orlando Bloom) accidentally knew that he was the long-lost illegitimate son of the Crusader General Godfrey (Liam Neeson). In order to find redemption, Balian followed his father to Jerusalem. Brave and good at fighting, coupled with noble character, Balian has become a famous warrior after several battles. Not only is he deeply appreciated by the king, but the beautiful Princess Sibella (Eva Green) also has a secret love for him. And he was also deeply attracted by the strange and peculiar culture of the local area. However, as the battles increased, bringing endless killing and plunder, Balian finally understood the true meaning of peace and the true love of life in his father's teachings. The king of Jerusalem died and the new king succeeded. The warlike new king provoked a war, and Saladin led the Sasaracen Knights to recapture their holy land-Jerusalem. In a critical moment, Balian stepped forward and vowed to defend the "Kingdom of Heaven"...
