China's largest private media group, Huayi Brothers, has joined forces with Fox International Productions (FIP) and Star Television Asia Limited (STAR) to release the romantic comedy "Hot Summer Days" (Quancheng Relian), which will premiere on Friday.

Set in Beijing, Shenzhen and Hong Kong, the film consists of six intertwined love stories starring A-listers such as Daniel Wu and Vivian Hsu.

Veteran film maker Paul Cheng and fashion photographer Wing Shya co-direct the film. Huayi Brothers will distribute the film in the Chinese mainland and FIP outside it. STAR holds pay-TV rights throughout Asia, except for China.

China's film market is growing fast, with an annual 20 percent box office revenue increase over the past five years, which is making Hollywood conglomerates such as FOX and Disney speed up their cooperation with local companies. Huayi announced it would cooperate with Disney and Shanghai Media Group (SMG) to make a Chinese version of High School Musical last month.
