I saw the trailer in the theater the other day and I was blown away by the footage. It's amazing how they get so close to those animals. And focusing in on three families of animals sounds like a nice change of pace from the usual nature documentary (don't get me wrong though, I could spend days glued to the Discovery Channel).
And as some of you Planet Earth fans might already know, director Alastair Fothergill worked on this film as well! With the amount of awards under his belt, I'm confident that this film will be equally spectacular.
