Kingdom of Heaven is a 2005 epic historical fiction drama film directed and produced by Ridley Scott and written by William Monahan. It stars Orlando Bloom, Eva Green, Ghassan Massoud, Jeremy Irons, David Thewlis, Brendan Gleeson, Edward Norton, Marton Csokas, Liam Neeson, Michael Sheen, Velibor Topić and Alexander Siddig.
The story is set during the Crusades of the 12th century. A French village blacksmith goes to the aid of the Kingdom of Jerusalem in its defence against the Ayyubid Muslim Sultan, Saladin, who is fighting to claim back the city from the Christians; this leads to the Battle of Hattin. The screenplay is a heavily fictionalised portrayal of the life of Balian of Ibelin (c. 1143–93).
