This film investigates the variety of stories surrounding the New Testament account of the crucifixion, death, resurrection and ascension of Jesus, by interviewing historians, theologians and historical researchers. This exploration of the latest theories about what really happened to Jesus 2000 years ago uncovers some surprising possibilities. At the heart of the mystery is the suspicion that Jesus might not actually have died on the cross. The film concludes that it was perfectly possible to survive crucifixion in the 1st Century - there are records of people who did. But if Jesus survived, what happened to him afterwards? One of the most remarkable stories concerns the charismatic preacher Jus Asaf (Leader of the Healed) who arrived in Kashmir in around 30 AD. Just before he died at the age of 80, Jus Asaf claimed that he was in fact Jesus Christ and the programme shows his tomb, next to which are his carved footprints which bear the scars of crucifixion.

Following last year's enchanting film using special effects to re-create the gestation of mammals such as elephants and dolphins, we're now shown what goes on in a woman's uterus when she's conceived twins, triplets or even quads. The footage is accompanied by specially commissioned poetry by Roger McGough and Brian Patten, which, while delightful, sounds a bit too cosy for a quasi-scientific documentary. But the real-life endoscopic footage and the "4-D" ultrasound scans are fabulous and there are intriguing biological snippets, including the suggestion that one in eight of us may have started life in the womb with a sibling.

This film by the documentary-maker Martin Durkin presents the arguments of scientists and commentators who don't believe that CO2 produced by human activity is the main cause of climate change.

The film was shortlisted for the Best Documentary award at the 2008 Broadcast Awards.

A dramatized, very accurate version of the bitterness of the partition of British India. Although this story had been brought to the screen many times in Gandhi, Sardar, Jinnah, Lord Mountbatten-The Last Viceroy, but unless history is backed up by facts, testimonies and eye-witness accounts, it cannot be considered authentic. Similar to this production was a 3-part BBC documentary titled END OF EMPIRE - India in which was shown the closing 2 years of the Raj. But here we see the story from the day Mountbatten and his delegation arrive in India.

Have you ever wondered what it would look like if all the clothes, washing machines and toilet paper you ever used were piled up outside your front door? Or if you were to lay out all the bread you will ever eat or cups of tea you will drink? This beautiful, landmark film uses art and science to explore the impact each and every human has on the planet in an average lifetime, demonstrating the massive scale of everything consumed and produced in one lifetime. Human Footprint also features several experts, who explain the science behind the installations and explore the profound effect our individual footprints will have on the planet. From our babyhood, when we get through a massive 3,796 nappies and produce 254 litres of urine, through to our old age and death - by which time we will have had sex 4,239 times, eaten 10,866 carrots, taken 7,163 baths and done an average of 15 farts a day - this extraordinary film tells the story of an average life, the story of our human footprint.

It says a lot that whereas the US President resides in a massive mansion and the Russian premier has a medieval fortress, our own Prime Minister has to make do with running the country from a modest terraced house. In this one-off documentary, affable English Heritage chief Simon Thurley looks at buildings as manifestations of power and charts the history and symbolism of Downing Street, the Kremlin and the White House and what they tell us about their respective nations. It's full of diverting details, including one neat architectural gag: when he redesigned the state rooms at Downing Street in the 1980s, architect Quinlan Terry included above a doorway, as a cheeky reference to Mrs T, a tiny goldleaf figure of a thatcher. Simon Thurley, head of English Heritage, takes you inside the buildings whose tenants rule the world.Love, hate, treachery, barbarity, and base politics have all left their mark, as the presidents and prime ministers come and go. But the buildings remain silent witness to their deeds, and misdeeds. Each of them is expressive of national character: the pokiness of Number 10, a reminder to prime ministers that they are our servants; the pristine set of the White House, a stage from which the planet is run; and the overpowering brutality of the Kremlin, testament to so many dark deeds, and the line of unchallenged power that links the Czars to Russia's present day leader. The programme enjoys unique access to these places: the Russians even cleared Red Square for Simon, so impressed were they by the Queen's adviser on architecture. And it poses a key question. In the age of international terror, as these buildings defences are shorn up, are their inhabitants increaingly divorced from the very people they're supposed to serve, by the places they work in? The decision to go to war, the decision to assassinate, is now so much more easily taken from within their walls. So are we, just as much as they, prisoners of the Powerhouses?

The country's crudest comic opens the door to his shocking world. This one-hour observational documentary follows Roy as he tours the country. Royston Vasey, a.k.a. Roy 'Chubby' Brown, is Britain's rudest comedian, infamous for his outrageously racist, sexist and homophobic gags. It's an accolade that's meant he's never been allowed to perform on TV. But this has turned out to be more of a blessing than a curse as he's done very well for himself off the back of his army of fans buying his videos, DVDs, audio cassettes and show tickets. But how different is Roy Vasey from his stage persona 'Chubby' Brown? Film maker Will Yapp follows him around for a few months in 2005 and attempts to find out, following Roy as he goes on tour, re-visits his home town of Middlesborough, shares his family life and prepares for his first appearance on TV in 18 years on The Frank Skinner Show. Are the bigoted, offensive jokes he tells on stage just his act or personal views with a nastier edge to them?

A look at the tasteless jokes comedians tell and the controversy they cause.

Ruhal Ahmed and Shafiq Rasul became known as the Tipton Taliban after they were picked up by US forces in Afghanistan and spent two years in Guantanamo Bay. They were accused, along with a friend, of having had weapons training with the Taliban, meeting senior Al-Qaeda figures and taking part in the Islamist terror war against the United States. They protested their innocence and, after they were released without charge in 2004, claimed that they had been tortured during their incarceration. But the pair are plagued by suspicious looks and whisperings of 'no smoke without fire'. They have volunteered to have Professor Sean Spence test them to prove their innocence. What were they doing in Afghanistan? Why did they visit a Taliban stronghold? And why were they with Taliban fighters when they were captured? When they answer these questions in the scanner, the technology doesn't quite give them the response they had hoped for. The Tipton Taliban were the subject of 'The Road to Guantanamo'; a Michael Winterbottom docudrama which was broadcast by Channel 4 in 2006.

In 1967, four unknown actors in a kids TV show become the biggest pop band in the world. In America they outsold Elvis and The Beatles combined. They were...The Monkees. But The Monkees were not a real band, they were a man-made money-making machine, driven by ego and ambition, a machine that would ultimately crash and burn. This is the inside story of pop music's first manufactured band. Labelled the pre-fab four, The Monkees were the first manufactured pop group. And with the radical TV show and contagious pop songs, they attracted a cult following that survives to this day. But behind the sugary smiles and bubblegum pop of The Monkees lay a cut-throat business enterprise, one fuelled by money, ego and the ambition of some of the biggest names in Hollywood. And one that, ultimately, was to end in tears. With access to Davy Jones, Peter Tork and Micky Dolenz as well as The Monkees archive, Making The Monkees is the inside story of the rise and fall of this unlikely group. It is the story of four young men who were hand picked to become overnight superstars melting the hearts of teeny-boppers worldwide and lining the pockets of their creators. But it's also the story of how The Monkees - and the men who pulled their strings - created the blueprint for the boy-band phenomenon that is so prevalent today - from the prototype casting and marketing, to the inevitable tantrums over artistic control and the ensuing commercial failure.

To help her grow and develop she had been fitted with a feeding tube and Susan managed her feeding regime. However, the child was admitted to hospital with massive blood sodium levels, and suspicion fell upon Susan. Had she added salt to the little girl's feeding tube?

Her brothers and sisters refute her claims completely, going as far as to suggest that Kathy's book be sold as fiction, instead of autobiography. Who is telling the truth? Professor Sean Spence, who has pioneered the use of functional magnetic resonance imaging to detect when someone is lying, scans Kathy and her brother while they respond to each other's allegations. Can Kathy back up the claims she made in her autobiography? Will her brother's testimony reveal that she is lying?

The Definitive Assessment Of The Blair Decade In a landmark series, the policies and personality of the man who has ruled Britain for the last decade are examined by Andrew Rawnsley, the award-winning broadcaster, author and commentator who is widely regarded as one of the most authoritative chroniclers of New Labour's time in power. This major two-part series both provides the definitive assessment of the Blair decade and tells the inside story of New Labour over the past ten years. The series features exclusive interviews with senior Cabinet members, civil servants, generals, and allies, opponents and intimates of Tony Blair, who speak to Rawnsley with extraordinary candour about the Prime Minister's greatest successes and his gravest misjudgements. The series includes interviews with close friends of Tony Blair who have never before spoken on the record and to camera. The programmes deliver a comprehensive, revelatory and incisive examination of the events at home and abroad that shaped the Blair premiership. Rawnsley analyses the political relationships forged by Blair, the opportunities, threats and challenges he has faced from 1997 until his final days at Number 10, and the successes and disasters of his period in power. Rawnsley shows that Blair was hugely daunted by power and arrived at Number 10 with deep inner anxieties about whether he was up to being Prime Minister. He soon found that his promises were not matched by detailed strategies to fulfil them. Senior members of Blair's Cabinet admit to Rawnsley that the Government suffered from a lack of worked-out policies. Blair's closest aides and allies express regret that they too often concentrated on the spin at the expense of the substance.

The film looks back at the development of the gang and charts its rise to vicious power and the investigation that sought to bring down as many of the leaders as possible.

Hitler's Favourite Royal is the extraordinary but little known royal story of the British prince who became a convicted Nazi. Prince Charles Edward was Queen Victoria's youngest grandchild. Brought up at Claremont House and educated at Eton until he was 14, Charles Edward was forced by Queen Victoria to take up the Dukedom of Coburg in Germany after a series of unexpected deaths of uncles and cousins.

The Hindu god, Krishna, was conceived by a virgin and his birth was attended by angels, wise men and shepherds. Buddha was also the result of a miraculous birth, and was visited by wise men bearing gifts. He too began his ministry at about 30 years old and performed such miracles as walking on water and feeding 500. Some people in India believe that Jesus did not die on the cross but escaped from Roman Palestine and ended up in Kashmir. There, they say, he continued to preach, had a wife and child, and later died and was buried. Jesus was, of course, born a Jew, and Christians believe he is the Messiah prophesied in the Torah – the Old Testament, which is the holy scripture of the Jews. Meanwhile Muslims revere Jesus as a prophet but do not believe he died on the cross; instead, according to Islam, God saved him and took him up to heaven, and he will return and be buried next to Muhammed. In this Channel 4 Christmas Day programme, Robert Beckford attempts to unravel the mystery of why there are so many versions of the Christ story across the world and asks which is the real one, and where this leaves the Christian story and his own belief in Jesus.
