This new feature-length biographical film tells the extraordinary and dramatic story of the planet's most famous living scientist, told for the first time in his own words and by those closest to him. Made with unique access to his private life, this is an intimate and moving journey into Stephen Hawking's past and present. Interviewees include Stephen Hawking's sister Mary, his ex-wife Jane, carers and students, as well as colleagues such as Roger Penrose, plus Apollo astronaut Buzz Aldrin, actors Benedict Cumberbatch and Jim Carrey, and Sir Richard Branson This inspirational portrait of an iconic figure relates Hawking's incredible personal journey from boyhood underachiever to scientific genius and multi-million-selling author. And it charts how he overcame being diagnosed with motor neurone disease - and being given just two years to live - to make amazing scientific discoveries and become a symbol of triumph over adversity. Born exactly 300 years after the death of Galileo, Hawking grew up in a family some regarded as eccentric. Always asking questions, he was nicknamed 'Einstein' at school. Hawking blossomed at Oxford, although he only spent an hour a day studying. He noticed that he was becoming clumsy and fell over for no apparent reason. He was diagnosed with motor neurone disease, but nevertheless started a family and embarked on his academic career, finding himself at the heart of a searing scientific debate about the origins of the universe. And as he lost the use of his body, Hawking had to find new ways to think. He went on to write the huge bestseller A Brief History of Time, and the film reveals the high and lows of his resulting fame and fortune.

Yet it was at the hands of Cortes and the Spanish conquistadors that Montezuma met his downfall. But what was his relationship with Cortes, and why did such a ruthless leader submit to his captors with such relative ease? As Dan Snow visits the ruins and picks through current excavations, he pieces together the evidence of a gripping story: a divine tragedy of errors, the clash of civilisations, the end of a world - and a very human God.

Dawkins reveals how he came to write The Selfish Gene in 1976, an explosive book which divided the scientific community and made him the most influential evolutionary biologist of his generation, and how this made him an outspoken spokesman for atheism.

In 1995, during the making of his TV series Triumph of the Nerds about the birth of the PC, Bob Cringely did a memorable hour-long interview with Steve Jobs. It was 10 years since Jobs had left Apple following a bruising struggle with John Sculley, the CEO he had brought into the company. At the time of the interview Jobs was running NeXT, the niche computer company he had founded after leaving Apple. During the interview, Jobs was at his charismatic best - witty, outspoken, visionary. In the end, only a part of the interview was used in the series and the rest was thought lost. But recently a VHS copy was found in the series director's garage. Now, cleaned up with modern technology, and put into context by Cringely.
