This summer, The Odyssey, a film directed by British filmmaker Christopher Nolan, became a global box office phenomenon. At a time when superhero films and established sci-fi franchises dominate the mainstream, a story based on Homer's epic, which was written nearly 3,000 years ago, once again captured audiences around the world. The discussion it sparked has gone far beyond the film itself. From war and peace to civilization and barbarism, people are using an ancient Greek story to revisit the problems confronting society today.
