I love Sir David Attenborough! Some of my fondest memories growing up were watching his shows on PBS with my family. The way he talks and grips audiences without all of the antics that a lot of the newer hosts use is a lost art form. I even bought the Planet Earth series with him as the narrator instead of Sigourney Weaver (although she did a good job too).
Wow, I didn't realise they re-voiced them for the US market! Is this usual for British productions that make it over the pond?
Is this working for anyone outside the UK? I get "This content doesn't seem to be working. Try again later." when I visit http://www.bbc.co.uk/wildlifefinder/ - are they using their usual IP filtering?
