To get a golden eagle’s eye view a miniature camera was strapped to the bird’s back, while a world champion paraglider flew down the mountain using a special parachute to get immersive motion shots.

　　为了能给观众提供绝佳的金雕视角，我们将一个微型摄像机绑在鸟背上，并让世界冠军级的滑翔伞运动员用特殊的降落伞从山上滑下，来拍摄这种身临其境的镜头。

　　光有科技还不够，摄制团队是在用生命拍纪录片。

　　他们历时3年多，历经117趟摄制之旅，走访40个国家，才拍出这些震撼人心的画面。

　　其中的艰辛是常人很难体会的：

　　The crew camped under the stars for their entire time in Botswana – five months spread over two years – as they filmed swamp lions hunting buffalo.

　　两年中，摄制组有整整五个月不分昼夜地驻扎在博茨瓦纳（非洲南部内陆国），来拍摄沼泽雄狮捕食水牛的镜头。

　　They were surrounded by hyenas, crocodiles and hippos and while in the swamps they went barefoot so they would feel a potentially deadly crocodile beneath their feet.

　　鬣狗、鳄鱼和河马徘徊在他们周围，而当他们赤脚趟进沼泽地时，有致命危险的鳄鱼就在他们脚下。

　　After a 7-day crossing by small yacht, the team spent more than 2 weeks camping beside a penguin colony in Antarctica.

　　拍摄企鹅时，摄制组坐了7天的小游艇，才抵达南极洲的企鹅聚居地，然后在那里搭帐篷拍了两周。
