Mudbound

ALEX Gibney is a hero of the documentary scene.

Previous works such as The Armstrong Lie and We Sell Secrets are rightly feted, and you just know when he chooses a subject, you are in for an educating, absorbing piece of cinema.

His latest film, No Stone Unturned, is running at the Curzon Bloomsbury and tells the story of how six men were shot dead in a pub in the village of Loughinisland, Northern Ireland, while they watched a World Cup match in 1994.

He considers the failings of a poor police investigation, revisits the evidence and considers why no one was ever brought to justice for this awful mass murder.

And next week, DocHouse has a Q&A with the directors of Karl Marx City, a story from Cold War East Germany. It is called a “powerfully personal voyage as filmmaker Petra Epperlein investigates her father’s suicide and the possibility that he may have worked as a spy for the Stasi security service”. The screening will be followed by a Q&A with co-directors Petra Epperlein andMichael Tucker. See dochouse.org/cinema/screenings

• Mudbound is a drama set in Mississippi during the 1940s, and tells the story of two families on either sides of a racial divide.

Out on general release this week, it is adapted from the novel by Hillary Jordan and focuses on the story of a white farming family, the McAllans, and the sharecropping Jacksons who work on the land.

This film is about poverty and its effects – racism, violence and a nation uncomfortable with itself.
