As artificial intelligence accelerates at a breathtaking pace, filmmaker Daniel Roher sets out to understand whether humanity is approaching an extraordinary new era or a catastrophe of its own making. What begins as a personal investigation becomes far more urgent when he and his wife learn they are expecting a child. Faced with predictions ranging from revolutionary medical breakthroughs and powerful new tools for creativity to mass unemployment, deepfakes, autonomous systems and even existential risk, he asks some of the world’s leading AI thinkers a deceptively simple question: should we be excited about the future, or terrified of it? The film explores how generative AI works, why its capabilities are advancing so quickly and what could happen if increasingly powerful systems become difficult to control. Experts debate AI safety and alignment, the race between competing companies, the possibility of machines seeking greater power, and the social consequences of automation and concentrated wealth. At the same time, the documentary confronts the technology’s remarkable promise, from personalized education to scientific discovery and potential cancer treatments. Moving between anxiety and hope, Roher ultimately searches for a way to face an uncertain future not as a pessimist or a blind optimist, but as something in between: an “Apocaloptimist.”
A mass grave at Zultepec, Mexico, containing more than 400 mutilated skeletons forces archaeologists to reconsider one of the most familiar stories of the Spanish conquest. Led by Aztec specialist Elizabeth Baquedano, the investigation follows forensic clues hidden in skulls, bones and artifacts to identify the victims and reconstruct what happened. Some remains prove to be European, including women, while Spanish-made iron objects and evidence of horses link the dead directly to the conquistadors who entered Mexico in the early sixteenth century. The evidence reveals a far more violent confrontation than the traditional image of an easy Spanish victory. Captured Spaniards and members of their entourage appear to have been imprisoned, ritually sacrificed, dismembered and, in some cases, consumed as part of ceremonial practices. By combining archaeology, forensic anthropology and Aztec codices, the documentary shows that indigenous resistance to the conquistadors could be organized, successful and terrifyingly effective, transforming Zultepec into crucial physical evidence of a conflict that history had long oversimplified.
Professor Brian Cox joins Chris Lintott and the team to investigate one of the most intriguing new mysteries in modern astronomy. Observations from the James Webb Space Telescope have revealed hundreds of compact, extraordinarily bright objects known as “little red dots”, appearing less than a billion years after the Big Bang. Many may hide rapidly growing supermassive black holes, raising a profound question: how could such enormous objects have formed so early in cosmic history? The journey begins with the strange physics of black holes themselves, from event horizons and singularities to the supermassive black hole at the centre of the Milky Way and the gigantic black hole in the galaxy M87. With cosmologist Emma Chapman and Professor Sadegh Khochfar, the programme explores radical explanations for these ancient monsters, including primordial black holes born soon after the Big Bang and massive black holes formed directly from collapsing clouds of gas, bypassing stars altogether. Cutting-edge computer simulations recreate the first billion years of the universe and reveal how the earliest galaxies and black holes may have emerged within the cosmic web. These discoveries are forcing astronomers to reconsider not only how supermassive black holes grow, but how galaxies and the early universe itself evolved.
From ordinary mounted warriors to the legendary figures who came to embody courage, honour and chivalry, medieval knights dominated European life for centuries. Through dramatic reconstructions, historical experiments and surviving evidence, this series reveals the harsh reality behind the romantic image: brutal battles and personal feuds, swordsmanship and tournaments, the construction and defense of castles, courtly love and the strict codes of honour that could turn an insult into a fight to the death. It also follows knights to the Holy Land, where crusaders risked everything in pursuit of glory, wealth and salvation, while figures such as John of Bohemia and Joan of Arc show how courage and legend became inseparable from the medieval warrior. Presented here as all three episodes consecutively in a single video, the complete story also reveals how the world that created the knight eventually destroyed him. The rise of robber knights such as Götz von Berlichingen, the spread of mercenary warfare and increasingly spectacular tournaments mark the final years of an old order, while longbows, cannon, artillery and massed infantry transform the battlefield forever. Emperor Maximilian, celebrated as the “Last of the Knights,” embraces these new weapons even as he glorifies the traditions of chivalry. By the end, the armoured horseman who had ruled castles, battlefields and entire communities for centuries has become obsolete in war—but immortal in legend.
Captured during her Manchester shows on a sold-out world tour, this concert film brings Billie Eilish closer than ever, turning the stage into a dark, emotional and visually hypnotic space where every whisper, scream, silence and movement feels intensely personal. Co-directed with James Cameron, the film transforms a live performance into a cinematic experience, surrounding the audience with the atmosphere, scale and intimacy of one of the most distinctive artists of her generation. More than a concert recording, it becomes a journey through the sound and emotion of Hit Me Hard and Soft, where fragile ballads, explosive moments, dreamlike lighting and the roar of thousands of fans collide in one powerful experience. Billie moves between vulnerability and confidence, loneliness and connection, softness and strength, creating a show that feels both massive and intimate. The film invites viewers not just to watch the performance, but to feel as though they are part of it.
An ambitious scientific quest is underway to recreate the power of the Sun here on Earth. This fascinating documentary takes viewers inside one of the most complex engineering projects ever attempted: the construction of the world's largest nuclear fusion reactor. Bringing together thousands of scientists, engineers, and technicians from dozens of countries, the project seeks to harness the same process that powers the stars and transform it into a virtually limitless source of clean energy for future generations. With unprecedented access to the massive ITER facility in southern France, the documentary reveals the extraordinary challenges of building a machine capable of containing plasma hotter than the Sun itself. Through stunning visuals, cutting-edge technology, and firsthand accounts from the people making it possible, the film explores the race to unlock fusion energy, the scientific breakthroughs required to achieve it, and the potential to revolutionize humanity's energy future if this historic experiment succeeds.
