Kingdom of Heaven Review

I am writing a review over what was not historically accurate in the 2005 movie, Kingdom of Heaven.  The King of Jerusalem was confirmed to have leprosy but did not necessarily wear a mask like he did in the movie.  Also, when Saladin was attacking Jerusalem he did not show mercy in the movie but in reality he would have, in order to preserve innocent people's lives and he wanted to live in the city itself.  He would also have not used fireballs to attack Jerusalem.  It was also said in the movie that Balian was from France but in reality his life would have been centered in Jerusalem.
