Watch HDToday. 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.
