I bought the DVD set narrated by Sigourney Weaver in September 2009, after seeing part of it on TV. Now almost four years to the day, I am finally watching the entire series and enjoying it immensely. I haven't seen the one narrated by David Attenborough so I can't compare. I do enjoy Ms. Weaver's narration; she has an agreeably low-pitched voice that doesn't get in the way, so to speak. There have been times on another series where I found Mr. Attenborough's narration a bit distracting, so decided to go with the US version.
I see Planet Earth is now available for video streaming on Amazon Prime (though not free to Prime members yet); not sure who the narrator is on the Prime series.
Someone mentioned how often Ms. Weaver mentioned 'now for the first time...' or words to that effect. I am noticing that also the more I watch, but still really enjoying it. The photography is truly astonishing. I'd love to be flying over those peaks--climbing them, not so much. Edited by cjs123 - 9/7/13 at 6:45pm
