HONG KONG — Hong Kong-made movies may soon be imported into China’s Guangdong Province without restriction under a new ruling.Local reports claim the Cultural Dept. of Guangdong has secured permission from the central government’s State Administration for Radio, Film and Television to lift import quotas for their films, but no start date was given. This will chiefly benefit smaller movies, which find it hardest to qualify for release in the wealthy and populous province that borders Hong Kong and shares the Cantonese language. One Hong Kong producer-distributor estimated lifting the restriction could double the B.O. of some titles. Larger-budget pics, which are co-produced with mainland firms, can access China through the Closer Economic Partnership Arrangement.
