Disney and Robert Zemeckis in talks for rights to “Stoneheart” books “The Stoneheart Trilogy,” a young-adult fantasy book series by Charlie Fletcher, is moving towards a big-screen adaptation with Robert Zemeckis and Disney in negotiations to pick up film rights to the material. The books revolve around a 12-year-old London boy who enters a hidden alternate world where statues, imbued with the soul-like essence of their makers, come to life. The boy’s presence upsets a balance between good and evil, and while dealing with such creatures as sphinxes and gargoyles, he teams with an orphan girl and the statue of a World War I gunner to try to set things right. The intent is to adapt “Stoneheart” using performance-capture technology. The third “Stoneheart” book, “Silvertongue,” is due in stores next month.
