RIYADH: Christopher Nolan’s “The Odyssey” is proving to be more than a box-office hit, particularly in the Gulf, where it has drawn a sizable audience. The film’s global success has spotlighted Greece’s mythology-rich culture and breathtaking landscapes as never before. News outlets across the world are dubbing this the “Odyssey effect,” referring to the way the feature film is influencing traveler behavior, with visitor numbers reportedly on the rise.
