Traven, Rory Haines, and Sohrab Noshirvani, adapted from Slahi's 2015 memoir Guantánamo Diary.

It starred Tahar Rahim as Slahi, and also featured Jodie Foster, Shailene Woodley, Benedict Cumberbatch, and Zachary Levi in supporting roles.

[1] It received mixed to positive reviews, with critics praising Macdonald's direction, its cinematography and the performances of the cast (particularly of Rahim and Foster) but criticising its screenplay.

They haven’t seen Mohamedou since he was arrested three years ago and only just found out in a newspaper that he is being held by the United States at the Guantanamo Bay detention camp and is accused of being one of the organizers of 9/11.

Nancy finds out something through Mohamedou’s letter which she received from him while Stu looks at the MFR (Memorandum for the Record), showing exactly what happened.

The letter and reports talk about enhanced interrogation methods (i.e., torture) and other maltreatment including sexual assault upon Mohamedou by the Guantanamo guards as ordered by General Mandel.

Nancy and Teri are still lawyers working against injustice, and we see footage of Mohamedou giving them necklaces with their names in Arabic.

Kevin Macdonald signed on as director, with Benedict Cumberbatch, Jodie Foster, Tahar Rahim and Shailene Woodley cast to star.

The film was originally known as Guantánamo Diary in its early development stages,[7] and as Prisoner 760 during production,[8] before being described as untitled in post-production.

The film was released alongside Judas and the Black Messiah, Land and limited expansion of Willy's Wonderland on 12 February 2021.

The website's critics consensus reads: "The Mauritanian takes a frustratingly generic approach to a real-life story that might have been inspirational in other hands, but Tahar Rahim's performance elevates the uneven material.
