The documentary film, “Koran by Heart” follows the progress of three scholars, a girl and two boys, all 10 years old, as they compete in Cairo against students who, in some instances, are nearly twice their age in the annual International Holy Koran Competition. Directed by Greg Barker (HBO) the film captures touching moments of the three children at home with their families, where they open up about life and religion, academic dreams and career aspirations.
