Using 5 video cameras and 4 film sets including a moving subway train, Mitchell’s The Forbidden Zone is a reflection of WW1 and the deployment of Chlorine gas in the true story of the Haber family.

The 'Chemists War' of 1914–18 witnessed the deployment of the first weapon of mass destruction – poison gas. At the heart of the race to weaponise gas is the tragic story of the Haber family. Clara Immerwahr gave up her career in chemistry when she married the Nobel Prize-winning Fritz Haber. When Haber's research turned to the development of Chlorine gas and its implementation in Ypres, Clara's protests at this 'perversion of science' were unheard. Her fate was to be echoed in 1949 in Chicago when their grandchild, Clarie Haber, saw her poison gas antidote research terminated as military funding turned to atomic warfare.

Renowned for her innovative staging and immersive theatrical worlds, Katie Mitchell is among the most inventive directors in Britain. This unique theatre production uses five video cameras and four film sets – including a moving subway train – to create a dynamic live cinema event.

The Forbidden Zone is live streamed from the Salzburg Festival.
