At a press conference held today in Beijing, Tsui said the film will start shooting at the end of January.
Set in contemporary Beijing, the $5m comedy will portray a range of modern-day Beijing women.
Zhou Xun will play 12 different women in various professions; Gui Lunmei will portray a rebellious young woman with fighting skills, and Zhang Yuqi will play an intelligent and wealthy woman. Korean filmmaker Kwak Jae-yong (My Sassy Girl) has scripted the film.
Besides She Ain't Mean, J.A. Media's two 2007 co-production projects - Jump, directed by Stephen Fung, and Miao Miao, from Taiwanese filmmaker Cheng Hsiao-zer - have completed shooting.
The former, starring Zhang Yuqi and Edison Chan, is co-produced by Stephen Chow's Star Overseas. Miao Miao, starring Fan Chih-wei and Ke Chia-yan, is co-produced with Wong Kar-wai's Jet Tone Films. J.A. Media will take charge of mainland Chinese distribution of both films.
The company is also preparing a Bruce Lee biopic, to be directed by Stanley Kwan, and Ann Hui's Concubine's Children. Both aim to start shooting this year.
