There is not a cynical molecule in the makeup of George Miller's "Three Thousand Years of Longing," a patient and occasionally dazzling fantasy about love, myth, hope, companionship and perhaps, most of all, about storytelling. Idris Elba and Tilda Swinton, wrapped in plush white bathrobes, will reiterate the storytelling point over and over again during a vulnerable, sprawling conversation in a stately Istanbul hotel suite that's nice enough to make one consider a career in academia.
