Mormon filmmakers have continued to produce movies centered around LDS missionaries, but often from new perspectives; "The Saratov Approach" (2013) was a thriller set in Russia, "The Errand of Angels" (2008) focused on female missionaries, and "Freetown" (2015) told the story of African missionaries escaping the First Liberian Civil War. On the subject of film, author Heather Bigley writes: "As American members [of the LDS Church] begin to think of themselves as part of a world-wide organization, efforts at self-definition abound." There have also been recent releases in the vein of LDS Church history, such as "The Fighting Preacher" (2019) and "Out of Liberty" (2019). The Mormon films released since 2005 have mainly been small, independent features. They are, however, arguably of a higher artistic quality than their predecessors, and tend to have a "moral of the story." There has arguably been more variety in Mormon cinema in more recent years. In March 2021, LDS filmmaker Barrett Burgin argued that films made by and about Latter-day Saints still have the potential to be marketable to a larger audience, but stressed the need to prioritize storytelling over a missionary message. He also identified some elements of LDS doctrine, culture, history, and lore—such as polygamy, violence, buried treasure, folk magic, and miracles—as marketable film elements. These, he said, range from "radically weird" to "clean-cut and conservative," and the intrigue surrounding that dichotomy could attract the interest of viewers.
