If you're a fan of the Blue Planet and Planet Earth documentary series, then there's a good chance you've already heard about the forthcoming collaboration between the BBC and the Discovery Channel, Frozen Planet.
Well, the BBC just put up the trailer for Frozen Planet on their YouTube channel, and it looks downright amazeballs. It's got the same production team as TBP and PE, and David Attenborough will be returning to do the narrating, so we've got high expectations for this one. The series will begin airing on BBC One starting this month, and will make its way stateside by spring of next year.
