Comet ISON can well be the brightest and most spectacular comet for a generation. It appeared above the eastern horizon from December 2013 as a glorious streak across the sky. ISON has been travelling towards the sun for ten thousand years and will make only one orbit through its corona before disappearing off into the outer solar system.
But as well as providing a great spectacle, ISON's tail of vaporised gas and water, hundreds of millions of kilometres long, will give insights into some of the greatest mysteries of science; it will help explain the origins of the solar system, whether earth's water was delivered on comets and even whether we are alone in the universe.

Award winning wildlife photographers Jonathan and Angela Scott have travelled the world, always returning home to Kenya. There they introduced the world to the big cats of the Maasai Mara and now they are part of its fight for survival.

Half of the population in Western society suffers from being overweight. Cardio-vascular diseases, diabetes and cancer are epidemic. Our meat consumption has quintupled over the past 50 years. 65 billion land animals are being slaughtered every year for food consumption. One third of the global grain production is fed to animals for fattening while 1.8 billion people worldwide suffer from hunger and starvation. Can there really be a solution to all these problems?
H.O.P.E. is a life-changing documentary uncovering and revealing the effects of our typical Western diet high in animal-based foods. It contrasts the limited interests of the pharmaceutical and agricultural industry with the all-encompassing interests of living beings on this planet and with the power of responsible consumer action. H.O.P.E. is an urgent call to action to all of us to commit to a change towards sustainability and safeguarding our living environment.

A decade after An Inconvenient Truth brought climate change into the heart of popular culture comes the riveting and rousing follow-up that shows just how close we are to a real energy revolution. Vice President Al Gore continues his tireless fight, traveling around the world training an army of climate champions and influencing international climate policy. Cameras follow him behind the scenes-in moments private and public, funny and poignant-as he pursues the empowering notion that while the stakes have never been higher, the perils of climate change can be overcome with human ingenuity and passion.
Renowned filmmakers Bonni Cohen and Jon Shenk have taken the baton from 2006 Academy Award-winner Davis Guggenheim. What started then as a profound slide show lecture has become a gorgeously cinematic excursion. Our extraordinary former vice president invites us along on an inspirational journey across the globe that delivers the tools to heal our planet. The question is: Will we choose to take the baton?

The five directors, John Ford, William Wyler, John Huston, Frank Capra, and George Stevens, return to Hollywood after the war but are forever haunted by what they saw. Ford goes on a drinking bender after filming the carnage at D-Day. Stevens is wholly unprepared for the horrors of Dachau and realizes he is not there to film propaganda but to capture evidence of crimes against humanity. Wyler, who lost his hearing during the war, fears his career is over. Huston chronicles soldiers suffering from postraumatic stress disorder in the film Let There Be Light, only to have it suppressed by the U.S. government.

In the second episode, the directors learn their vision for the films is not always permissible by the U.S. government. Wyler is shocked by the racism he encounters against African American soldiers and refused to make a film recruiting black soldiers. Meanwhile, the films' racist depiction of the Japanese versus human depiction of the Germans causes worry for the War Department, which at that time planned to redistribute the Japanese-American population from internment camps into towns across the United States.
