"King Richard and the Crusaders." This classic (that you may be able to see on Turner Classic Movies from time to time) is from 1954, and it deserves the third spot on this list of the best films about the Crusades because of its all-star cast. It features Rex Harrison as the Muslim Saladin and George Sanders as the glorious upholder of Christianity and all its goodness, who must clash against Saladin to prove he's the good guy in this whole melee.
"The Crusades." This film about the Crusades is even older than the preceding one, but its director, Cecil B. DeMille, makes this film one for the record books. Mostly about the Third Crusade, this sweeping epic of Middle Eastern romanticism tells the tale of the great, Christian hero, Richard the Lionhearted, and how he has to rescue his one, true beloved (played by the okay-looking Loretta Young) from the clutches of the evil Muslim Saladin, who steals his love and tries to force her to choose him, instead!
"Saladin." From 1963 comes this decent attempt at a Crusades film, at number five on this list mainly because it is a film from Egypt, which means that the subtitles and cultural differences may make it harder to digest for Western audiences. Still, you must be wary when watching this film, because Richard the Lionhearted is portrayed as an infidel who is only "honorable" after he basically decides to retreat back to Europe.
