Deep Blue is a major documentary feature film shot by the BBC Natural History Unit, the same team that produced the acclaimed BBC series The Blue Planet. Set to a sweeping score by George Fenton (Dangerous Liaisons, Shadowlands) and with narration from Sir Michael Gambon, Deep Blue is an epic cinematic rollercoaster ride for all the ages with footage that will amaze viewers with their beauty and stun them with their grandeur.

Despite the fact that the sea constitutes two thirds of our planet, we know more about the surface of the moon than we do about the deep oceans. Assembling 20 specialised camera teams, over the course of 5 years directors Alastair Fothergill and Andy Byatt shot over 7000 hours of footage in more than 200 locations around the world for more than five years. New species of ocean dwellers were discovered and many were photographed for the first time ever!
