Finding Nemo comes to life in this eye-popping nature documentary, a distilled version of the BBC's Blue Planet series that takes the viewer on an epic journey through the briny deep. Culled from more than 7,000 hours of footage shot over five years, Alistair Fothergill and Andy Byatt's feature comes with a classy score by George Fenton and lucid narration from Michael Gambon. Not that it really needs them: with images this mesmerising, it would work as a silent movie.
From surfing dolphins and leaping penguins to marauding killer whales, Deep Blue strives to bring us up close and personal with a vast array of creatures as it charts their perpetual battle for survival against an ocean's-worth of predators. As remarkable and revealing as it is, however, it can't hope to match the bigger picture that was presented by the TV series. If you've seen that, you already know all you need to about the Big Blue's hidden secrets.
