Mainstage Chichester Festival premiere of a beautifully written historical play about the real people and events behind the Gunpowder Plot - to mark the 400th anniversary. It's 1605, and England is riven between Catholic and Protestant. An aristocratic group of young religious fanatics has recruited a mercenary, Guy Fawkes, to strike at the heart of the English Government. But under the ambivalent rule of the new King James I, fresh from Scotland, no one can be trusted and their plot is going to be turned against the very people it was meant to save. This incendiary thriller weaves together the lives of kings and terrorists, priests and spies in a play of epic proportions, which has the sweep and scope of the very best historical drama. "5/11" premieres in the 1200-seater Chichester Festival Theatre in a production by Steve Pimlott with Alistair McGowan as King James heading a terrific cast of 25 including John Ramm, Hugh Ross and Richard O'Callaghan.
