If you haven't put two and two together yet I'm sorry to have to break the news.
The new movie "Earth" uses footage from the tv mini-series "Planet Earth."
It has been trimmed down to 90 minutes, Sigourney Weaver was dumped for James Earl Jones, and of course it is on the big screen.
If you've seen Planet Earth don't expect any new footage, just a new format. Either way, what was a great tv series will look great on the big screen.
