The ground breaking series from BBCAmerica, 'Planet Earth'  made it's debut yesterday and will continue over the next four weeks.

The video and images are some of the first times that anyone has ever seen the events in their natural habitat.  You would think that with footage this powerful, that a voice wouldn't make that big of a difference, but it does.

Sigourney Weaver and Sir David Attenborough are two of the voices behind the original series, but they weren't the only people to audition.

Check out some of the behind the scenes auditions that BBC America received for the series.
