Directed, produced, and narrated by Oliver Stone. In this episode we will see how the equation changes: specific month-by-month causes of the Cold War emerge and it is not entirely clear who started it. Highlights include Churchill's Iron Curtain speech, the civil war in Greece and the Red Scare that prompts the rise of Joseph McCarthy, the House Un-American Activities Committee and the FBI.

This episode of the documentary series focuses on the new giants, the heavyweights of the dinosaur world. It is only in recent years that experts have unearthed the biggest dinosaurs that ever lived. One monster eclipsed all others; more than seven times as heavy as diplodocus was the immense argentinosaurus - a single backbone was bigger than a human. For years, these giants were considered immune to attack from any predator - until the discovery of mapusaurus, a new giant killer whose fate appeared to be inextricably linked to argentinosaurus

Horizon explores the strange and wonderful world of illusions – and reveals the tricks they play on our senses and why they fool us. We show how easy it is to trick your sense of taste by changing the colours of food and drink, explain how what you see can change what you hear, and see just how unreliable our sense of colour can be. But all this trickery has a serious purpose. It’s helping scientists to create a new understanding of how our senses work – not as individual senses, but connected together. It holds the intriguing possibility that one sense could be mapped into another.

This is the story of three maps, three 'visions' of London over three centuries. The Morgan Map of 1682 was the first to show the whole of the City of London after the Great Fire of London. In 1746 John Rocque produced at the time the most detailed map ever made of London. Like Morgan's, Rocque's map is all neo-Classical beauty and clinical precision, but the London it represented had become the opposite. In engravings of the time, such as Night, the artist William Hogarth shows a city boiling with vice and corruption. Stephen Walter's contemporary image, The Island, plays with notions of cartographic order and respectability. His extraordinary London map looks at first glance to be just as precise and ordered as his hero Rocque's but, looking closer, it includes 21st century markings such as 'favourite kebab vans' and sites of 'personal heartbreak'.

brilliant mathematicians whose genius has profoundly affected us, but which tragically drove them insane and eventually led to them all committing suicide. Kurt Gödel, the introverted confidant of Einstein, proved that there would always be problems which were outside human logic. His life ended in a sanatorium where he starved himself to death. Finally, Alan Turing, the great Bletchley Park code breaker, father of computer science and homosexual, died trying to prove that some things are fundamentally unprovable.

Annalisa Piras and former editor of The Economist Bill Emmott, which explores the crisis facing Europe. Through case studies of citizens in different countries, the film explores a range of factors that have led to the present crisis, economic and identity challenges across Europe. High-level experts analyse how and why things are going so wrong. The film includes fictional scenes, set in a post-EU future, which feature archaeologist Charles Granda (played by Angus Deayton) travelling on a flight through a menacing storm, explaining to a child passenger what the EU was. Sombre, thought-provoking and witty, the film frames Europe through the eyes of those who have most at stake - the Europeans themselves.
