Unfolding over seven and a half hours, The Long Walk follows local women as they journey to collect water in Sudan’s Nuba Mountains. I fully immersed myself in the walk, filming continuously for seven and a half hours to capture both the monotony and the intensity of this ritual, while revealing the extraordinary endurance required to survive amid civil war, landmines, and the threat of personal violence.

The final film retained its full seven-and-a-half-hour duration and was first presented publicly on a 30-foot LED screen in Trafalgar Square on 31 October 2006, accompanied by public addresses from the Secretary of State for International Development, the Right Honourable Hilary Benn MP, London Mayor Ken Livingstone, and WaterAid CEO Dame Barbara Frost.

It subsequently went on to be exhibited on large screens around the world, including Trafalgar Square in London; the UN building in Brussels; Grand Central Station in New York; Union Station in Washington, DC; Victoria City Centre in Australia; the Eden Project in Cornwall; and Glastonbury Festival, where it was shown for five consecutive years.

The final screening took place in 2012 at the Cathedral of St John the Divine in New York, as part of An Evening of Witness, accompanied by a live orchestra and organised by the Magnum Foundation.
