Filmmaker Sean Casey’s personal quest to capture the birth of a tornado with a 70mm camera takes viewers on a breathtaking journey into the heart of the storm. A team of equally driven scientists, the VORTEX2 researchers, experience the relentless strength of nature’s elemental forces as they literally surround tornadoes and the supercell storms that form them, gathering the most comprehensive severe weather data ever collected.

Antarctica lives in our dreams as the most remote, the most forbidding continent on Planet Earth. It is a huge land covered with ice as thick as three miles, seemingly invulnerable, cold and dark for eight months of the year. Yet Antarctica is also a fragile place, home to an incredible variety of life along its edges, arguably the most stunning, breathtaking and still-pristine place on earth. The one constant is that it is constantly changing, every season, every day, every hour. I've been fortunate to travel to Antarctica many times; most recently with 3D cameras, a first for the continent. The result is our new film, Antarctica: On the Edge.

Titans of the Ice Age transports viewers to the beautiful and otherworldly frozen landscapes of North America, Europe and Asia ten thousand years before modern civilization. Dazzling computer-generated imagery brings this mysterious era to life - from saber-toothed cats and giant sloths to the iconic mammoths, giants both feared and hunted by prehistoric humans.

Misrepresented, maligned and on the verge of extinction, the great white shark is an iconic predator: the creature we love to fear. Great White Shark will explore the great white's place in our imaginations, in our fears and in the reality of its role at the top of the oceanic food chain. The film will concentrate on key aggregation points around the world: Mexico, South Africa, Los Angeles and New Zealand. Key figures in the history of shark research, people whose lives have been changed by contact with the great white, will tell us of their experiences, culminating in a direct encounter between man and shark.
