A Perfect Planet was four years in the making with crews around the world gather footage for the documentary and while most of it was mostly plain-sailing, there were some challenges.
Producer Huw Cordey said of filming: “In terms of the whole process, there was six months pre-production, about two or three years filming and the rest post-production.”
He continued: “My first month on this was in January 2016, so it’s been quite a long undertaking.”
Additionally, the Coronavirus pandemic created some obstacles with Sir David resorting to new technology to record some of the voiceover parts during lockdown, which he wholeheartedly embraced.
While producers had to bring together an orchestra in Iceland to perform the score with the brass and woodwind sections recorded separately by musicians separately in their homes and added to the score later.
A Perfect Planet airs on BBC One on Sunday at 8pm
