the final episode deals with plants that live in hostile environments. Attenborough visits Ellesmere Island, north of the Arctic Circle, to demonstrate that even in a place that is unconducive to life, it can be found. Algae and lichens grow in or on rock, and during summer, when the ice melts, flowers are much more apparent. However, they must remain close to the ground to stay out of the chilling wind. In the Tasmanian mountains, plants conserve heat by growing into 'cushions' that act as solar panels, with as many as a million individual shoots grouped together as one. Others, such as the lobelia in Mount Kenya, have a 'fur coat' of dense hairs on their leaves. The saguaro cactus in the Sonoran Desert flourishes because of its ability to retain vast amounts of water, which can't be lost through leaves because it has none. Many desert dwellers benefit from an accelerated life cycle, blooming rapidly within weeks after rainfall. Conversely, Mount Roraima is one of the wettest places on Earth. It is a huge sandstone plateau with high waterfalls and nutrients are continuously washed away, so plants have to adapt their diet if they are to survive. A bladderwort is shown invading a bromeliad. Inhabitants of lakes have other problems to contend with: those that dominate the surface will proliferate, and the Amazon water lily provides an apt illustration. Attenborough ends the series with an entreaty for the conservation of plant species.

Since Caesar's days, Germanic warriors and Roman legionaries had often met in battle. Rome's power seemed invincible. But then, in the year 9 AD, the Germans mounted a rebellion.

The documentary tells the story of the extremely rare discovery of evidence of Roman crucifixion, unearthed in a routine archaeological dig in the Cambridgeshire Fens. When human remains were found alongside a variety of Roman artifacts, none of the team at Albion Archaeology saw anything out of the ordinary. But once the bones were washed back at HQ, something highly unusual was uncovered: a nail through the heel bone of one of the individuals. Could this be evidence of a Roman crucifixion? When they did some research, they found that only one confirmed example had ever been unearthed before, discovered in the 1960s in Jerusalem. To find out more, they called in renowned osteoarchaeologist Dr Corinne Duhig to investigate. With exclusive access to Corinne’s investigation and the remains themselves, The Cambridgeshire Crucifixion sets out to find out who this person was, how they lived and why they were put to death in this notoriously gruesome way. We perform a CT scan, DNA and isotope analysis of the remains, and use them to create a cutting-edge virtual autopsy of the skeleton, conducted by Corinne and one of her former students, biologist Prof Ben Garrod.
A supporting cast of expert contributors help to analyse the artefacts found at the Fenstanton site and reveal a compelling picture of life in Roman Britain in the 1st century CE. The film culminates in a world first: a full forensic facial reconstruction of a victim of Roman crucifixion, conducted by world-leading expert Joe Mullins.

Years after he changed the landscape of filmmaking with The Exorcist, filmaker and writer William Friedkin moves from fiction to fact with this documentary. What began as a brief conversation between Friedkin and Father Gabrielle Amorth - the head Exorcist for the Diocese of Rome for over 30 years - as two professionals who knew of each other's work, soon transformed into an once-in-a-lifetime opportunity, as Amorth agreed Friedkin could film an exorcism ceremony. It would be the ninth exorcism for a painfully afflicted woman, and it would be filmed by Friedkin alone, with no other crew allowed, no light other than the natural light in the room and a small digital camera-and-mic unit that could capture the ritual and its revelations.
Combining the startling and singular footage from Cristina's exorcism with interviews from priests and psychologists, neurosurgeons and non-believers, Friedkin guides us on a journey into the twilight world between the boundaries of what we know and what we don't.

Professor Diarmaid MacCulloch - one of the world's leading historians - reveals the origins of Christianity and explores what it means to be a Christian. In the first episode, he overturns the familiar story that it all began when the apostle Paul took Christianity from Jerusalem to Rome. Instead, he shows that the true origins of Christianity lie further east, and that at one point it was poised to triumph in Asia, maybe even in China. The headquarters of Christianity might well have been Baghdad not Rome, and if that had happened then Western Christianity would have been very different.

This acclaimed multi-million dollar 4 part series shows the rise of the tribes of a primitive culture on the fringe of northern Europe to become the heirs of the Roman Empire. Since the age of Caesar this Roman-Germanic conflict was characterized not only by fierce battles but also by phases of co-existence & cooperation. the Germans dug the grave of the Roman Empire, but were also the preserves of the Roman legacy.
