How can the Church deal with claims of apparitions in an increasingly secular, disbelieving world? That is one of the questions at the heart of L’Apparition, a new film from French director Xavier Giannoli. Set in the present day, the action begins with the death of a war photographer in Syria. His journalistic partner, Jacques, played by the magnificently hangdog Vincent Lindon, returns to France, signed off work due to the physical and psychological damage wrought on him by the explosion that killed his friend.
