From the creator of Planet Earth (2006), producer Alastair Fothergill spent four years shooting in 50 countries with more than 600 crew members.
During an April 2019 interview with Ari Shapiro on the National Public Radio program "All Things Considered," series producer Alastair Fothergill was asked if there was there one particular scene that he was especially proud of having captured, and his response was to describe the extremely difficult process of capturing footage of a Siberian tiger: "It's the first intimate images of these amazing cats in the wild. And to give you a sense of how difficult it was, over two winters, three cameramen were literally locked away inside wooden hides. They didn't come out for six weeks. Everything you need to do to survive they did inside this small box.... And they worked for two winters. They got one, single shot of a wild Siberian tiger. At the same time, we had about 40 motion control cameras - remote cameras that are set off by the moving animal. And again, the first winter, we got nothing, really. We got lynx going past, other animals of the forest. But over that period, we began to see the movements of the tigers - how they were moving in that area. And the second season, we got 36 precious, precious images. For me, it's a wonderfully emblematic sequence of a wonderfully rare, wild, iconic species of the boreal forest."
