The protest, titled #LoveRefugees, will be marked by a series of screenings staged on Saturday at 7pm, with the UK, France Japan, Kenya and Tunisia confirmed as the first host countries.
Secret Cinema has revealed its upcoming secret screening at a central London location will coincide with the launch of a new initiative to install mobile cinemas across refugee camps in Europe.
Organisers said: "We are building a makeshift cinema in the Calais refugee camp for this event and with your support, we want to build further cinemas in camps worldwide, screening a wide cultural programme for both adults and children.
"We will send a powerful message to those that need to listen and ask you to join us in large numbers."
The ever-expanding community, generally better known for its large-scale productions, such as 'Back to the Future' and 'Star Wars: The Empire Strikes Back', which is still running, has asked everyone sympathetic to the plight of the refugees to donate what they can to join the Secret Cultural Protest.
Interested parties and other organisations are able to join the protest or host a screening in their city, wherever they are, by registering their interest with email@example.com.
