Michael Winterbottom, prolific director of films such as "Nine Songs," "In This World," "The Claim," "24 Hour Party People" and "Welcome to Sarajevo" is directing a documentary (with dramatic recreations) about the "Tipton Three", three Muslims who were held by the US government at Guantánamo Bay's Camp X-Ray Prison for two years without being charged. They were captured in Afghanistan while on their way to a wedding in Pakistan. Jason Deans and Owen Gibson report for The Guardian.
