This world-exclusive introduction to the show is narrated by series presenter Sir David Attenborough and set to an exclusive track developed by Hans Zimmer and Radiohead. The prequel features an array of some of the most awe-inspiring shots and highlights from the new series, as well as several exclusive scenes that will not feature in any of the seven episodes which are set for UK broadcast on BBC One later this year.
In several instances and shots, BBC has made use of the half-over half-underwater shots. To know how you can shoot your own videos like that, click here.
