Year after year hundreds of thousands of fans line the route of the Tour de France, cheering on their heroes and willing them to victory, while millions of viewers worldwide tune in on their televisions. Academy Award-winning director Pepe Danquart, fascinated by the spectacle of the three week race, chose to focus on the courage, the pain and the fear of the riders of the Tour. Training his lens on German superstar sprinter Eric Zabel and his loyal domestique Rolf Aldag, Danquart captures the thrill of the race and the teamwork behind the stars of the peleton. He also shines light on the Tour's supporting cast - the director sportifs, masseurs, and, of course, the wildly enthusiastic fans. Reveling in the stunning landscape - from the Alps to the Pyrenees to the Massif Central to Paris - and with a nice dollop of Le Tour's history, HELL ON WHEELS transcends the sport it celebrates to reveal an astonishing human endeavor.

In 1962, spurred by the Cold War, President John F. Kennedy famously made the bold proclamation that NASA would send astronauts to the moon by the end of the decade, not because it was easy, but because it was a challenge. The Space Race inspired a generation to pursue careers in science and technology, but as the balance of world power shifted, interest in space exploration declined. "Fight for Space" serves as an urgent call to re-awaken our sense of wonder and discovery.

As society tackles the problem of feeding our expanding population safely and sustainably, a schism has arisen between scientists and consumers, motivated by fear and distrust. Food Evolution, narrated by Neil deGrasse Tyson, explores the polarized debate surrounding GMOs. Looking at the real-world application of food science in the past and present, the film argues for sound science and open-mindedness in a culture that increasingly shows resistance to both.

The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen HAWKING has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells.

This film shows how far we have come since the cold-war days of the 50s and 60s. Back then the Russians were our "enemies". And to them the Americans were their "enemies" who couldn't be trusted. Somewhere in all this a young girl in Oklahoma named Shannon set her sights on becoming one of those space explorers, even though she was told "girls can't do that." But she did.

A group of renowned cosmologists and astrophysicist are in search of a realistic picture of the universe. Their research and observational discoveries point in a direction diametrically opposed to the predominant Bog Bang theory - this leads to a series of sociological situations that verge on the extreme dogma controls wielded against Copernicus and Galileo in the past; only now against our protagonists of the 21st century. This is a controversial science documentary touching on the nerve of everything astronomers and cosmologist claim they know about the universe today. - Written by Meyers, Randall

Bill Nye and Ken Ham debate whether creation is a viable model of origins in today's modern scientific era.

From the front lines of the bankrupt Chicago Tribune, to the vibrant local online publishing and start-up scene, pioneering journalists struggle to reinvent a storied, yet troubled industry.

Produced in the UK on a zero-budget, the filmmakers spent two years contacting and interviewing journalists, organisers and critics of the corrupt industrial practices highlighted by, but not limited to, the Leveson Inquiry in 2011. While the phone hacking scandal illuminated the depth and breadth of the cavalier flouting of legality and integrity in British journalism, there are larger implications and connections to ideology, entertainment, and political economy at work in this crisis. The Fourth Estate is the result of an examination of these connections at work.

In this highly anticipated sequel to his groundbreaking, ADVERTISING AND THE END OF THE WORLD, media scholar Sut Jhally explores the devastating personal and environmental fallout from advertising, commercial culture, and rampant American consumerism. Ranging from the emergence of the modern advertising industry in the early 20th century to the full-scale commercialization of the culture today, Jhally identifies one consistent message running throughout all of advertising: the idea that corporate brands and consumer goods are the keys to human happiness. He then shows how this powerful narrative, backed by billions of dollars a year and propagated by the best creative minds, has blinded us to the catastrophic costs of ever-accelerating rates of consumption.

This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.

Concern over global climate change may be at an all-time high, but climate change is nothing new - the earth's climate always followed natural cycles of warming and cooling. In Unstoppable Solar Cycles, Dr. Willie Soon and Dr. David Legates challenge the popular idea that human-generated CO2, is causing catastrophic global warming. These scientists propose an alterantive theory - that the current warming has more to do with solar activity than with human activity.
