Filmed across all seven continents over a period of 9 years, We Are Many reveals the true story of the people power movements now sweeping the world, from opposition to the Iraq War, to the Arab Spring and Syria.
Vietnam veteran Ron Kovic
says in the film:
"Something happened on that day that cannot be reversed."
In a series of interviews with prominent figures from the anti-war community, as well as frank inside accounts from those who launched the war, the film captures the shockwaves of public opinion - dubbed The Second Superpower by the New York Times.
We Are Many executive producer and comedian, Omid Djalili, commented:
"To be the world's no.1 Thunderclap for a micro-budget documentary like We Are Many is huge. We basically beat Hollywood. That's really something.
"The sheer number of people who joined up shows there's a clear appetite for this kind of content.
"We have widespread, mainstream support... it's not just hippies, activists or emotionally unstable men like me."
On Thursday May 21 at 8pm, selected cinemas across the UK will show a special screening of We Are Many, followed by a Q&A session broadcast live via satellite from the Curzon Mayfair.
Journalist and broadcaster Jon Snow will host the discussion with guests including the film's director Amir Amirani, executive producer and comedian Omid Djalili, Blur frontman Damon Albarn, convenor of the Stop The War Coalition Lindsey German, professor of international law at UCL Philippe Sands and Sense and Sensibility star Greg Wise.
Signing up to a Thunderclap enables a single message to be mass-shared, flash mob-style.
In what was the biggest Thunderclap ever for a film, the message "Join the march to cinemas and see the story of the biggest protest in history #WeAreMany", reached a massive 37,400,689 people.
