We Are Many: the legacy of the global anti-war protests in 2003 – video trailer world exclusive

We Are Many, directed by Amir Amirani, explores the legacy of the global anti-war demonstrations of 15 February 2003, an event that saw an estimated million people march against the Iraq war in London alone. Filmed over nine years, the film talks to key campaigners, including Damon Albarn, Ken Loach and the late Tony Benn, as well as those who made the decision to go to war. A special satellite screening of the film with a Q+A with Jon Snow takes place in London on 21 May, transmitted to select cinemas across the country, while the film is released on 22 May.
