Planet Earth—the much-loved cinematic tour of world's major ecosystems—is back in the form of Special Edition and Limited Collector's Edition DVD sets.
The sets add over three hours of bonus footage, including a preview of Alastair Fothergill's Frozen Planet, the forthcoming documentary from the BBC.
The following is a collection of images from the series, to celebrate the upcoming releases.
Here, a snow leopard—on of the rarest of Himalayan animals—hunts on the treacherous mountain slopes. Its large paws act as snowshoes in its snowy Himalayan terrain.
