The deep is perhaps the most hostile environment on earth, at least to us - a world of crushing pressure, brutal cold and utter darkness. We have barely begun to explore it, and yet it is the largest living space on the planet. Scientists already think that there is more life in the deep than anywhere else on earth. This episode takes us on an epic journey into the unknown, a realm that feels almost like science fiction. We discover alien worlds, bizarre creatures and extraordinary new behaviours never seen before. We encounter savage hordes of Humboldt squid hunting lanternfish in the depths and coral gardens flourishing in absolute darkness, with more species of coral to be found in the deep than on shallow tropical reefs. Narrated by David Attenborough.

Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour. Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.

‘Who Is in Control?’ explores the great deception that greets us each morning when we awake: it feels as though we are in conscious control of our lives but the truth is that we are not. Instead almost every action, every decision, every belief that we hold is driven by parts of the brain that we have no access to.

The film explores how artificial intelligence (AI) is catching up to us in ways once thought to be uniquely human: empathy, emotional intelligence and creativity. AI has the potential to reshape every aspect of our world – but most of us are unaware of what looms on the horizon. This documentary shows viewers what they need to know about a field that is advancing at a dizzying pace, often away from the public eye. Have AI the power to disconnect us from fellow humans? What does it mean when AI makes art? Can really AI interpret and understand human emotions? How is it possible that AI creates sophisticated neural networks that mimic the human brain?
The documentary includes interviews with global leaders, commentators and innovators from the AI field, including Geoff Hinton, Yoshua Bengio, Ray Kurzweil and Douglas Coupland, who highlight some of the innovative and cutting-edge AI technologies that are changing our world.

Mark Oliver Everett, singer of the band EELS, on his quest to get to know his later father, quantum physicist Hugh Everett III, who invented the Many Worlds theory. The film follows Mark on his journey across America, where he meets old friends and colleagues of his father. Hugh died of a heart attack in his home in 1982, where his body was found by 19-year-old Mark. Even though they had lived in the same house, the two of them were alienated. Only by entering the paradoxical world of quantum mechanics can Mark hope to understand why he was such a stranger to his own father.

In 1901, a group of divers excavating an ancient Roman shipwreck near the island of Antikythera, off the southern coast of Greece, found a mysterious object - a lump of calcified stone that contained within it several gearwheels welded together after years under the sea. The 2,000-year-old object, no bigger than a modern laptop, is now regarded as the world's oldest computer, devised to predict solar eclipses and, according to recent findings, calculate the timing of the ancient Olympics. Following the efforts of an international team of scientists, the mysteries of the Antikythera Mechanism are uncovered, revealing surprising and awe-inspiring details of the object that continues to mystify
