al-Risala is a biopic about the Prophet Muhammad and the early history of Islam, produced by Syrian American director Mustafa al-Akkad. Akkad's Hollywood fame stemmed from the Halloween series of horror films; later in his career he decided to make this contribution to global understanding of Islam at epic scale, filming English and Arabic versions with different casts. The script of al-Risala was carefully vetted by al-Azhar University in Cairo, but the film itself was ultimately banned in much of the Muslim world. (Akkad was killed in 2005 in a terrorist attack in Amman.) See this recent NPR story.
