The filmmaker taking Hong Kong's protests to Cannes

Just before the closing ceremony of this year's Cannes Film Festival, organisers had a surprise announcement - they were screening a film by Hong Kong director Kiwi Chow.

The documentary about the 2019 protests has a controversial title, named after a popular protest slogan that has since effectively been banned in Hong Kong after China passed a strict national security law.

But Kiwi says he does not want to be intimidated nor to self-censor.
