Directed by Alastair Fothergill, Andy Byatt and Martha Holmes. Narrated by Michael Gambon.
Essentially 'Blue Planet's Greatest Hits', 'Deep Blue' mixes some of the most stunning and acclaimed sequences from the now legendary BBC series into an 85-minute documentary. Some films make you want to eat, others make you want to sleep, this one will make you want to dive.
With 20 separate camera crews, 200 locations worldwide, three years of principal photography and 7,000 hours of footage, The Times wasn't exaggerating when it described this feat as "closer to a miracle than a television programme". And now those who missed out first time around - or those who can't get enough - can enjoy the magic.
From soldier crabs to blue whales and all the way down to the awe-inspiring Marianas trench, the 'Deep Blue' team captures both the grace of life and struggle for survival in or under the water. It's more look than learn, but you'll leave the cinema worried about the well being of our planet.
Gambon's sparse but near hypnotic voiceover compliments the dreamy visuals perfectly, and seems destined to find its way onto an ambient chilllout album at some stage. "We have sought out the stars and our moon," he intones wistfully near the close, "yet it is the ocean that continues to surprise us." Something of an understatement after what you've just seen.
Its audience will be small, but 'Deep Blue' puts the effects of all the summer blockbusters in the paddling pool.
