The filmmakers challenge former Indonesian death-squad leaders to reenact their mass-killings in whichever cinematic genres they wish, including classic Hollywood crime scenarios and lavish musical numbers. Anwar Congo and his friends have been dancing their way through musical numbers, twisting arms in film noir gangster scenes, and galloping across prairies as yodeling cowboys. Their foray into filmmaking is being celebrated in the media and debated on television, even though Anwar Congo and his friends are mass murderers.
Medan, Indonesia. When the government of Indonesia was overthrown by the military in 1965, Anwar and his friends were promoted from small-time gangsters who sold movie theatre tickets on the black market to death squad leaders. They helped the army kill more than one million alleged communists, ethnic Chinese, and intellectuals in less than a year. As the executioner for the most notorious death squad in his city, Anwar himself killed hundreds of people with his own hands.
The Act of Killing is about killers who have won, and the sort of society they have built. Unlike ageing Nazis or Rwandan génocidaires, Anwar and his friends have not been forced by history to admit they participated in crimes against humanity. Instead, they have written their own triumphant history, becoming role models for millions of young paramilitaries. The Act of Killing is a journey into the memories and imaginations of the perpetrators, offering insight into the minds of mass killers. And The Act of Killing is a nightmarish vision of a frighteningly banal culture of impunity in which killers can joke about crimes against humanity on television chat shows, and celebrate moral disaster with the ease and grace of a soft shoe dance number.

Can we find the Garden of Eden? Bible scholar Dr Francesca Stavrakopoulou thinks so. In the final episode of her series re-examining conventional readings of the Bible, she argues that the Garden of Eden has nothing to do with the origins of humanity, but is rather a story concealing dramatic events about a particular figure in a particular place, two and half thousand years ago. Marshalling compelling evidence from archaeology, Islam and the Bible text itself, she identifies and visits the exact site of Eden. It's a revolutionary theory which challenges some of the most cherished preconceptions about Eden in both Christianity and western culture.

It's a voyage of exploration like no other - to Titan, Saturn's largest moon and thought to resemble our own early Earth. For a small team of British scientists this would be the culmination of a lifetime's endeavour - the flight alone, some 2 billion miles, would take a full seven years. This is the story of the space probe they built, the sacrifices they made and their hopes for the landing. Would their ambitions survive the descent into the unknown on Titan's surface?

Morgan Freeman produces hosts and narrates this exploration of the greatest mysteries of the universe. The four forces governing our universe are phenomenally finely tuned, so finely that it had led many to the conclusion that someone, or something, must have calibrated them: an alien gameseter who's created our world as the ultimate SIM game for his own amusement.

Time is woven into the fabric of the universe as one of the dimensions in which we live our daily lives. But maybe it is only a brain state that we use to piece together events. Could it exist only in our minds? Your sense of time can be totally different than the person next to you. This and other theories illustrate that time is an illusion and does not really exist. The world's top physicists tackle this fundamental question, does time exist, and offer new ways to perceive the physical world.

An epic true story set against the backdrop of one of the wildest places on Earth, African Cats captures the real-life love, humour and determination of the majestic kings of the savannah.
