The great Sir David Attenborough isn't letting lockdown halt production on his latest nature documentary series.

According to the BBC's natural history commissioning editor, Jack Bootle, the 94-year-old broadcaster is putting the finishing touches to A Perfect Planet at his home in Richmond, southwest London.

Announced in February, the five-part series aims to "show how the forces of nature - weather, ocean currents, solar energy, and volcanoes - drive, shape, and support Earth’s great diversity of life." Attenborough has been filming links for the series in his garden to make sure it's finished on time, and has attached a duvet to a wall of his house to create a make-shift sound studio for his voiceover parts.

"I am confident that it will hit the screens," Bootle told The Mirror. "There’s small amounts of filming that remains to be done with Sir David and of course he also needs to record the voiceover. And there are some challenges involved with doing that during a time of lockdown."

"Assuming no disasters happen, that series will air as planned in the autumn, which we’re all very excited about," Bootle added.

Because of his advanced age, Attenborough is considered especially vulnerable to coronavirus and will have been advised by the U.K. government to stay at home.

He said of A Perfect Planet when it was announced in February: "Oceans, sunlight, weather and volcanoes, together these powerful yet fragile forces allow life to flourish in astonishing diversity. They make Earth truly unique, a perfect planet. Our planet is one in a billion, a world teeming with life. But now, a new dominant force is changing the face of Earth: humans. To preserve our perfect planet we must ensure we become a force for good."

Attenborough, who was named one of the 100 Greatest Britons of all-time in a 2002 BBC poll, has also been moonlighting as an online science teacher during lockdown.
