Planet Earth Live

Considering the spectacular wildlife filmmaking resume of the BBC Natural History Unit, it's quite impressive to say `Planet Earth Live' is the most ambitious live wildlife experience ever attempted by the BBC. But those are the network's words used to describe the real-time stories of the world's most charismatic animals, as presented by Richard Hammond and Julia Bradbury. The combination of the NHU's cinematography prowess as seen in `Frozen Planet' and the live techniques of `Big Cat Live' and `Springwatch' tell animal dramas around the world throughout May -- a time when bears emerge from their dens with baby cubs and gray whales migrate from the Pacific coast to the Arctic.
