描述：　　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.
