"Hostile Planet," a six-part series executive produced by Academy Award-winning cinematographer and director Guillermo Navarro (“Pan’s Labyrinth”), Emmy-nominated producer Martha Holmes (“The Blue Planet”), Emmy Award-winning Tom Hugh-Jones (“Planet Earth II”) and BAFTA winner Bear Grylls (“The Island”), draws attention to the most extraordinary — almost supernatural — accounts of animals that have adapted to the cruelest evolutionary curveballs. Hosted by survivalist and adventurer Grylls, the docuseries zooms in on the world’s most extreme environments to reveal the animal kingdom’s epic stories of survival on this fast and continuously changing planet. Grylls, Guillermo, Mateo Willis and Tom Hugh Jones come to BUILD to discuss the new Nat Geo series.
