Pianeta Blu - The Blue Planet (2001)

This definitive natural history of the world's oceans covers everything from popular shores and teeming shallows to the mysterious open depths. Two-thirds of the planet is covered by the oceans and yet they remain largely unexplored and certainly under-filmed. This series changes all that and subsequently changes our views of the deep. Advances in underwater photography has opened the doors to unknown territories never before explored.
