Netizens are having a growing influence on what makes it to the big screen. Xu Fan reports.

When filmmaker Li Shaohong watched the premiere of the animated movie The Legend of Qin, she was startled to see "numerous reviews suddenly flying onto the screen".

In the course of the China Film Director Guild chairwoman's 30-year career, it was the first time she had seen a film premiered in that way. Moviegoers were able to post real-time comments on the giant screen using mobile devices connected to the local wireless network.
