The Chinese government is planning to tighten its already strict film censorship rules. A proposal from the State Council, released on their website earlier today, is part of a draft law which proposes to ban anti-government sentiments and messages of religious fanaticism from the cinema screen. If passed, the bill, which comes during a box-office boom in China, will increase the number of banned subjects in Chinese cinema to 13. Another proposed ban could also prevent any film from “promoting” illegal drugs or terrorist activity.
