Bona Film Group Ltd, the Chinese film distributor and producer, has reported annual net revenues of $142.3 million for 2012, a 12.8 percent year-on-year increase, driven by its film investment, production and movie theater businesses.

Its film investment and production arms generated $73.7 million in net revenue, from $50.5 million in 2011, largely from the success of its first TV drama production, The King's Battles - an 80-episode series that premiered on multiple satellite networks in China.

Net revenues from its theater business rose to $41.7 million from $26 million in 2011, a 60.4 percent rise year-on-year, which the company attributed to an expansion of its theater activities across the country.
