In USA Today, Michael Medved reviews September Dawn, and writes that when it comes to terrorists, Hollywood much prefers them to be "Mormon, not Muslim":

[September Dawn's] deliberately drawn analogy between Mountain Meadows and 9/11 raises the most puzzling question about this peculiar project: Why frame an indictment of violent religiosity by focusing on long-ago Mormon leaders rather than contemporary Muslims who perpetrate unspeakable brutalities every day?

In fact, Hollywood's reluctance to portray Islamo-Nazi killers remains difficult, if not impossible, to explain. Since 2001's devastating attacks, big studios have released numerous movies with terrorists as part of the plot, including Sum of All Fears, Red Eye, Live Free or Die Hard, The Bourne Ultimatum and many more, but virtually all of them show terrorists as Europeans or Americans with no Islamic connections. Even historically based thrillers downplay Muslim terrorism: Steven Spielberg's Munich spends more than 80% of its running time showing Israelis as killers and Palestinians as victims, while Oliver Stone's World Trade Center highlights the aftermath of the attacks with no depiction of those who perpetrated them. United 93 stands out among recent releases in showing Islamic killers in acts of terror — and it would be hard to tell that story without portraying the suicidal hijackers.
