"Inside the Red Brick Wall" is a documentary that captures a major social event at Hong Kong Polytechnic University in November 2019.

[3][4] From January 10 to 22, 2020, the 13th Hong Kong Independent Film Festival featured the premieres of "Inside the Red Brick Wall" and "Taking Back the Legislature".

The Office for Film, Newspaper, and Article Administration (OFNAA) required warnings to be displayed before the screening, including statements such as “may constitute a criminal offense under existing laws” and “some content or commentary may be unverified or misleading.” On September 21, 2020, just two hours before its scheduled screening at the Hong Kong Arts Centre, the distributor received OFNAA’s approval, which reclassified the documentary as a Category III film, restricting viewers under 18 years old.

However, the pro-Beijing newspaper Wen Wei Po published an editorial accusing the documentary of spreading "anti-national sentiments" and violating the Film Censorship Ordinance and the National Security Law, urging OFNAA to ban it.

The jury praised the film, stating it "transforms into a universal story about a small group courageously facing a powerful authority through its writing and editing excellence.
