After spending the better part of a decade developing The Mauritanian, an adaptation of Mohamedou Ould Slahi’s memoirs detailing his 14 years of being tortured at Guantanamo Bay despite never being charged, Benedict Cumberbatch has become a fierce advocate for shutting down the prison camp that became a controversial holding facility for alleged terrorists in the aftermath of 9/11. Far too often, it’s been reported that detainees are actually innocent and were never given a chance to defend themselves outside of a military proceeding that is often stacked against them, and Cumberbatch is now planning to take his concerns straight to the top.
