Where does the truth lie and how are we, the people, supposed to decide? The film features Britain's pre-eminent sceptic Lord Christopher Monckton as he tours the world broadcasting his message to the public and politicians alike. Can he convince them and Murray that there is nothing to worry about?

To mark the centenary of the birth of one of the most iconic figures in recent American politics, a documentary which examines the enigmatic career of screen star and two-term US president Ronald Reagan. He has been heralded as one of the architects of the modern world and since his death many Americans have been working to cement his legacy, but some critics argue that the aftershocks of Reaganomics continue to crumble economies the world over and that the hubris of Reagan's foreign policy continues to propel America into a cycle of overseas ventures. To such critics Reagan is an ominous figure who did more harm than good. But who was Ronald Reagan, and how did he come to shape world politics in the way he did? Featuring in-depth interviews with those who worked with him and knew him best, this film provides a definitive and penetrating look at Reaganism, whose grip on the public mind has been rekindled by recent events in Republican politics.

That same night, hundreds of miles away on a different island, 19-year-old Paco Larranaga is at a party in Manila, surrounded by dozens of reliable witnesses. The missing women, Marijoy, 23, and Jacqueline Chiong, 21, are pretty and innocent Chinese-Filipinos from a working class community.

Ragnar Axelsson, known as Rax, is a photograher for Iceland's largest newspaper. This documentary follows him on his life's mission, to capture the human faces of climate change by photographing the vanishing lifestyles of the people of the north. Rax is among the most celebrated photographers in the world and his series of photographs, Faces of the North, is a living document of the dying cultures of the far northern reaches of the planet, mainly Icelandic farmers, fishermen and the great hunters of Greenland. 'It was really only one photograph that started me off,' he says. 'An old man in a rowing boat and his dog on a skerry. I thought to myself, these men are vanishing. If I don't photograph them now, no one will remember them and no one will know that they ever existed.' Rax spent his childhood summers on an isolated farm on the southern coast of Iceland, where the farmers lived off of the land as countless generations had before them. As a child he was enraptured by the landscape and the interactions between man and nature. Twenty-five years ago, his fascination with people who try to survive in extreme circumstances took him from Iceland to Greenland - a place which has continually inspired him to return. His photo essays of the hunters of Greenland are legendary. Rax could well have been a hunter himself - and we watch him as he stalks his images and strikes at the opportune moment. Fascinated by stories of half-forgotten people who have adapted to unspeakably harsh conditions, Rax is now documenting them as they cope with extreme changes to those conditions as the result of climate change. Last Days of the Arctic is a celebration of the photographer and his subjects, an elegy for a disappearing landscape and the people who inhabit it.

On 28 February 2009 Kaing Guek Eav, alias Duch, appeared in the ECCC courtroom and made a two-hour speech where he asked for forgiveness for the appalling torture and execution of at least 13,000 prisoners at Tuol Sleng and probably more in the security camps of M-13 and M-99. Until this date, with the exception of a handful of judges, lawyers and a priest, he had not been seen or heard of for the last thirty years. How did a man, known to be kind and generous to fellow students, possibly transform himself into Comrade Duch, the Khmer Rouge's infamous executioner? This documentary revisits and searches for clues.

Errol Morris broke cinematic ground with The Thin Blue Line, establishing a new genre in the non-fiction feature by creating a fascinating reconstruction and investigation of a brutal and senseless murder. The case in question is centred on the 1976 murder of a Dallas policeman. The murder remained unsolved for over a month until the Dallas police department received word that 16-year-old David Harris had been arrested in Vidor, Texas, after having bragged to friends that he killed a Dallas cop. Although the murder weapon was found in a nearby swamp, Harris later insisted that his boasting was meant only to impress his friends and insisted the real murderer was a hitchhiker he had picked up earlier that day named Randall Adams. Morris assembles diverse interviews, photo montages, film clips and reenactments of the crime to make a strong case for Adams's innocence, leading to a shocking finale.
