Caveat: In the Confessions Augustine writes of his hedonistic, amoral young adulthood, and those elements are present in this trailer. Watch it yourself first before allowing preteen viewing.
Ever since the semester I spent translating and studying St. Augustine's Confessions in college, I haven't been able to get enough of his writings. Now Ignatius Press is coming out with a cinematic adaptation of the Confessions! There hasn't been much information released yet, apart from the names of the lead actors and the fact that it should be coming out this fall. Keep an eye on their website and facebook page for future news.
UPDATE: A press release has come out with information about how you can get involved to bring Restless Heart to a theater near you.
