Documentary about progressive music and the generation of bands that were involved, from the international success stories of Yes, Genesis, ELP, King Crimson and Jethro Tull to the trials and tribulations of lesser-known bands such as Caravan and Egg. The film is structured in three parts, charting the birth, rise and decline of a movement famed for complex musical structures, weird time signatures, technical virtuosity and strange, and quintessentially English, literary influences.
It looks at the psychedelic pop scene that gave birth to progressive rock in the late 1960s, the golden age of progressive music in the early 1970s, complete with drum solos and gatefold record sleeves, and the over-ambition, commercialisation and eventual fall from grace of this rarefied musical experiment at the hands of punk in 1977. Contributors include Robert Wyatt, Mike Oldfield, Pete Sinfield, Rick Wakeman, Phil Collins, Arthur Brown, Carl Palmer and Ian Anderson.

Lucy Worsley travels to Russia to tell the extraordinary story of the dynasty that ruled the country for more than three centuries. It's an epic tale that includes giant figures such as Peter the Great and Catherine the Great, the devastating struggle against Napoleon in 1812, and the political murders of Nicholas II and his family in 1918 which brought the dynasty to a brutal end.
In this first episode, Lucy investigates the beginning of the Romanovs' 300-year reign in Russia. In 1613, when Russia was leaderless, 16-year-old Mikhail Romanov was plucked from obscurity and offered the crown of Russia. Lucy also charts the story of Peter the Great, the ruthless and ambitious tsar who was determined to modernise Russia at the end of the 17th century.

Comet ISON can well be the brightest and most spectacular comet for a generation. It appeared above the eastern horizon from December 2013 as a glorious streak across the sky. ISON has been travelling towards the sun for ten thousand years and will make only one orbit through its corona before disappearing off into the outer solar system.
But as well as providing a great spectacle, ISON's tail of vaporised gas and water, hundreds of millions of kilometres long, will give insights into some of the greatest mysteries of science; it will help explain the origins of the solar system, whether earth's water was delivered on comets and even whether we are alone in the universe.

The film intends to illustrate the birth and death of an undiscovered universe, with powerful images, from the Big Bang to the Mesozoic era and through the present and beyond. Based on a project conceived decades ago, the documentary is highly experimental and perhaps Terrence Malick's most ambitious film, described by the director himself as 'one of my greatest dreams.'

From dinosaurs to mammoths, when our ancient ancestors encountered the fossil bones of extinct prehistoric creatures, what did they think they were? Just like us, ancient peoples were fascinated by the giant bones they found in the ground. Historian Tom Holland goes on a journey of discovery to explore the fascinating ways in which our ancestors sought to explain the remains of dinosaurs and other giant prehistoric creatures, and how bones and fossils have shaped and affected human culture.
In Classical Greece, petrified bones were exhibited in temples as the remains of a long-lost race of colossal heroes. Chinese tales of dragons may well have had their origins in the great fossil beds of the Gobi desert. In the Middle Ages, Christians believed that mysterious bones found in rock were the remains of giants drowned in Noah's Flood.
Tom encounters a medieval sculpture that is the first known reconstruction of a monster from a fossil, and learns about the Native Americans stories, told for generations, which contained clues that led bone hunters to some of the greatest dinosaur finds of the nineteenth century.

On the coast, two worlds collide. Coasts are the most dynamic and challenging habitats in the ocean - that brings great rewards but also great danger. The extraordinary animals that live here must find ingenious ways to cope with two very different worlds. This episode is a rollercoaster ride of heart-stopping action and epic drama, peopled with characters from the beautiful to the bizarre. We meet fish that live on dry land and puffins that must travel 60 miles or more for a single meal, and witness a life-and-death struggle in a technicolour rock pool. In a secluded cove in the Galapagos, sea lions feast on 60kg tuna. It should be impossible - tuna are usually far too fast for sea lions to catch. But here the sea lions club together to herd their prey inshore. Once trapped in the shallows, these huge fish are easy pickings. As the tide recedes in Brazil, lightfoot crabs leap from rock to rock, desperately avoiding the water - their lives depend on it. Moray eels launch themselves from rock pools, jaw gaping. Then octopuses, too. Both crawl across dry rock to set their ambush. Elsewhere, the ever-changing tides create rock pools. But these temporary worlds are a battleground. Predatory starfish turn a magical garden into the stuff of nightmares.
