Well - this series has totally captivated all of us - my eight year, too. Before I go any further, let me start by saying - WOW - GO BUY THIS. It's hands-down the best $54.00 I ever spent. Hours and hours of the most incredible footage I've ever seen. Simply stunning.
I've been subscribing to National Geographic for over 15 years and can't help feeling cheated!
This 5-disc compilation, narrated by the venerable David Attenborough, has shown me more about the world, introduced me to animals I'd never before seen or heard of (and I used to work in a zoo!!) and environments I never knew existed.
According to the back blurb, it was 5 years in the making, with over 2000 hours in the field. Each 'segment' (jungles, shallow ocean, seasonal forests, caves - my personal fave, pole-to-pole, rivers, etc...) is one hour long, followed by a 10 minute segment called Planet Earth Diaries, where they give you some insight into how they got some of the amazing footage. What these people go through for a single stunning shot is really incredible.
Days and days and days of sitting in bird blinds in a hot sticky rainforest for a 30 second shot of a bird-of-paradise displaying for a female (totally worth it, btw) makes me shake my head in awe at these dedicated crews. Or trekking for 10 days into a cave system to film the stunning Lecheguilla (sp?) with its white crystals - I'm still breathless over that one.
I really could go on and on about it -- just ask my sister who had to listen to me wax endless on the phone last night -- but I'll spare you and just say again - GO BUY THIS SERIES. NOW.
You will not be disappointed, in fact, you will be sending me accolades! ;)
