 The Keynes Film Festival will show a new documentary on Friday, cronling the 2019 Hong Kong Pro-Democracy protest and shining a light on the protestor's stories in a surprise addition to the lineup for the cinema showcase. Revolution of Our Times by native Hong Kong filmmaker Kiwi Chow follows several protesters and documents clashes with police in what the director previously described to networks as his attempts to help the movement live on. China introduced a sweeping national security law a year ago to crack down for whatever seems like a subversion, a secessionism, terrorism and collusions with foreign forces and cinemas, universities and ad galleries have cancelled screenings or exhibitions of protest-related works. The Hong Kong government recently enacted new guidelines that allows authorities to censor films on the basis of safeguarding and national security.
