Narrated by Sir David Attenborough and from the award-winning team behind Planet Earth & Blue Planet comes the ultimate portrait of the earth's Polar regions. The Arctic and Antarctic remain the greatest wildernesses on Earth.
EDIT: Due almost certainly to the massive interest from HUKDers today, this item is now currently showing as "temporarily out of stock". You can still order for £4.74, just be sure to select Amazon as the seller. They will honour the price as long as you order before the price changes.
Enjoy....you won't be disappointed!
