Faced with the threat of big-budget Hollywood productions, ethnic Chinese filmmakers are fighting back by closing ranks and pooling talent, money and ideas with their Asian counterparts. The strategy: casting big-name Japanese and Korean stars with regional appeal alongside Chinese actors to target more markets across the region and forming creative alliances that can create better movies and appeal to a broader range of investors. As a result, budgets and quality are going up and, in turn, raising the prospect of opening up foreign markets and of even challenging Hollywood in the world entertainment industry. The rise of Korean film and pop culture is a big part of the equation. AP reports.
