To outsiders, Turkmenistan is one of the world's least known countries. For the first time in ten years, a film crew has been free to visit spectacular excavation sites and follow international researchers into areas that have long been off-limits. Once considered the poorest part of the Soviet Union, oil and natural gas have brought new wealth to Turkmenistan today. A little known fact in the West is that 4,000 years ago, the country was home to one of the ancient world's centers of power. Although it flourished around the same time as the advanced civilizations of Mesopotamia and Egypt, the Margiana empire was later largely forgotten. Since the fall of the Soviet Union, the country has been slowly opening up to international researchers, and its astounding cultural heritage is coming to light.

"No discovery of our time has so moved the whole world," proclaims an intertitle introducing this special extended newsreel edition. For once, Topical Budget's characteristic hyperbole is on the money. The discovery and excavation (some would say grave-robbing) of the tomb of the 14th Century BC Egyptian pharaoh was already an international sensation by the time this newsreel screened in February 1923. The sense of breathless excitement surrounding the discovery extends to Topical's intertitles, which expend a good portion of the film's running time explaining the relatively fleeting, poor quality images of the excavation itself. But we do get to see the removal of an ebony, ivory and gold chair, and two glimpses of expedition leader Howard Carter - in long-shot from behind as announced in an intertitle, but also a much clearer, unheralded shot at the 'halfway rest house', where he cuts a dash in white shirt and trousers.

What exactly happened to all the objects found by Howard Carter after he finished exploring Tutankhamun's tomb in 1930 after they had been lying there for the past 3200 years? The most precious of them are exhibited in the Egyptian Museum in Cairo but most were kept out of sight from the very beginning. Ninety years later, for the first time, most of these objects will finally be brought together in the precinct of the great Museum of Giza. Some of them will make their way to the U.S.A. and Paris, where they will be exposed at the Cité des Sciences et de l'Industries in the autumn of 2018 - and then in London, Berlin, Tokyo and…

In 1587, more than 100 English colonists settle on Roanoke Island and soon vanish, baffling historians for centuries; now, experts use the latest forensic archaeology to investigate the true story behind America's oldest and most controversial mystery.

Up to one million gladiators are thought to have died in arenas across the Roman Empire. And, although fascination with gladiators has been high, the details of their lives and deaths remain fragmentary. Now, with the discovery of an ancient Roman burial site containing 80 skeletons thought to be gladiator warriors, National Geographic recreates the world of the Roman arena and how six gladiators lived, fought and died.

In this hour-long documentary, Oxford academic Janina Ramirez tours the country in search of Anglo-Saxon art treasures. Her basic thesis - and it is a plausible one - is that we should not look upon their era as a "dark age" as compared, for example, to Roman times, but rather celebrate it as an age in which creativity flowered, especially in terms of artistic design as well as symbolism. She shows plenty of good examples, ranging from the Franks Casket to the Staffordshire Hoard, and the Lindisfarne Gospels. - l_rawjalaurence
