It’s not uncommon for a director to release two films in one year, but Academy-Award winning—for his 1999 documentary One Day in September—director Kevin Macdonald is guilty of this achievement multiple times. Ten years ago, he released his first crowd-sourced documentary Life in a Day and the period epic The Eagle within months of each other. A decade on, he’s done it again.

The Scottish director (and grandson of legendary filmmaker Emeric Pressburger) released both his Life in a Day follow-up and the legal drama The Mauritanian this month. The latter tells the story of Guantanamo Bay detainee Mohamedou Ould Slahi (sometimes written as Salahi), who was held and tortured in the notorious US detention center for fourteen years without a charge. The film, adapted from Slahi’s 2015 memoir Guantánamo Diary, features Jodie Foster and Shailene Woodley as his defense attorneys Nancy Hollander and Teri Duncan, with Benedict Cumberbatch, who also signed on as the film’s producer, playing prosecutor Lt. Stuart Couch.

The Mauritanian also introduces French star Tahar Rahim to a global audience, in the role of Slahi. “The ensemble is excellent across the board,” writes Zach Gilbert, “while Tahar Rahim is best in show overall, bringing honorable heart and humanity to his role [of] the titular mistreated prisoner.”

Much of the story is filmed as an office-based legal thriller involving thick files, intense conversations, and Jodie Foster’s very bright lipstick. Macdonald expertly employs aspect ratio to signify narrative shifts into scenes recreating Slahi’s vivid recollections of torture and his achingly brief conversations with unseen fellow detainees.

Qualifying for this year’s awards season due to extended deadlines, The Mauritanian has already earned Golden Globe nominations for Best Actor and Best Supporting Actress for Rahim and Foster respectively. Slahi remains unable to travel due to no-fly lists, but he was a valuable resource to the production, providing an accurate and rare depiction of a sympathetic Muslim character in an American film.

How did you approach creating an honest representation of the graphic torture scenes, without putting the audience through it as well?
Whenever films about this period are [made] they’re always from the point of view of the Americans and this time we’re with Mohamedou. You can’t underestimate the fact that there have really been no mainstream American cinematic portrayals of Muslims at all, so in portraying a sympathetic Muslim character who’s also accused of terrorism, you’re pushing some hot buttons with people. It was important that those people who are uncomfortable with him understand why he confessed to what he confessed.

Everything you see in the film is what happened; the only difference is that they weren’t wearing masks of cats and Shrek-like creatures, they wore Star Wars masks of Yoda and Luke Skywalker in this very perverse fucked-up version of American pop culture. Obviously, we couldn’t get the rights to those. Actually, I don’t feel that it is graphic. There is more violence in your average Marvel movie. It’s psychologically disturbing because you’re experiencing this disorientating lighting, the [heavy-metal] music, and he’s being told his mother’s going to be raped and he’s flashing back to his childhood. To be empathizing with this character and then to see them to be so cruelly treated is so deeply disturbing.

How did you prepare Tahar Rahim for his convincing portrayal of such intense pain and suffering?
Tahar went through a great deal of discomfort in order to achieve it. He felt that to give a performance that had any chance of being truthful, he needed to experience a little bit of what Mohamedou had suffered, so throughout the movie he would insist on wearing real shackles which made his leg bleed and give him blisters. I would plead with him to put on rubber ones and he would say “no, I have to do this so I’m not just play-acting”.

He starved himself for about three weeks leading up to a torture sequence—he had lost an awful amount of weight and he was really unsteady on his legs. I was very worried about it and I got him nutritionists and doctors but he was determined to stick with that. You’ve got to understand that for a Muslim man like Tahar, this role has a much greater significance than it does for you or me. He felt a great weight of responsibility to do this correctly, not just for Mohamedou, but he was speaking for the whole Muslim world in a way.

Did anything surprise you in how your subjects for Life in a Day 2020 addressed the pandemic?
One of the most affecting characters in the film is an American who lost his home and business because of the pandemic, so he’s living in his car. He seems very depressed when you meet him for the first time, then later he’s telling us there’s something that’s giving him joy in his life. He brings out all these drones with these cameras on them and puts on this VR headset and loses himself by flying through the trees. I thought that was such a great metaphor for the way that human ingenuity has enabled us to survive and thrive during the pandemic.

I get the feeling of resilience from [the film]. This is a more thoughtful film than the original one. I see this as a movie of [us] being beware of our susceptibility to disease and ultimately to death and mortality, [and] how we’ve found these consolations as human beings. To me, it’s a really profound thing. It also speaks to the main theme of the film which is how we’re all so similar, same as The Mauritanian. It’s confronting you with all these people and saying we fundamentally all share the basic things that underpin our lives and the differences between us are much less important than the things we have in common.

Let’s go from Life in a Day to your life in film. What’s a Scottish film that you love but you feel is very overlooked or underrated?
That’s really hard because there aren’t many Scottish films and there aren’t many good ones. Gregory’s Girl is the greatest Scottish film ever made—it’s the bible for life for me. That’s very well-known, so I would have to say Bill Forsyth’s previous film That Sinking Feeling, which was self-funded and made on 16mm black-and-white. It has some of the same actors and characters as Gregory’s Girl in it. Or my grandfather Emeric Pressberger’s film I Know Where I’m Going! which is a rare romantic comedy set in Scotland.
