The latest David Attenborough nature documentary series, shot in HD.
This ambitious 2006 series, described as 'the definitive look at the diversity of our planet' was the first ever to be filmed entirely in high definition.
Every episode but the first one looks at one of the Earth's natural habitats and examines its local features, together with the breadth of fauna found there.
While filming it, the crew caught several firsts - places and animals never before caught on camera.
The fact that it was co-funded by Discovery Channel, BBC and Japan's NHK, took 5 years to make and was shot in over 200 locations is apparent and the series is everything you'd expect from Sir David Attenborough and his team if they were unconstrained by budget or practicality.
