This show is simply badass. It’s a sequel, technologically and narratively, of sorts to Blue Planet, but features all sorts of new filming techniques (was done all in HD though it is not being broadcast that way), helicopter gimble-cams, Nepalese spy-planes, and a seeming focus on things that have rarely been filmed (for various reasons). Also the most expensive documentary the BBC has ever done ($40+ million), and they’ve split it into two “series” I guess, 5 episodes in the spring and 6 in the fall. Not sure when it’ll be available in the US, but it is really cool and worth watching if you like nature programs.
The torrent I got doesn’t include the 10-minute “diary” which did come with a version I found on the newsgroups, which is an interesting behind-the-scenes look at the wild dog hunt segment.
