The 89-year-old naturalist - who is known for his therapeutic voice-overs - is gearing up to narrate the forthcoming natural history series 'Planet Earth II', a collection of six one-hour nature episodes, a decade after the first show hit screens.

Speaking about his new challenge, he said: "I am very excited to once again be working with the Natural History Unit on its latest landmark series and am especially looking forward to getting out on location in the next month or so."

The forthcoming show, which originally used the working title 'One Planet', will be the most high-tech series ever mounted by the corporation as it uses ultra-high-speed cameras mounted on drones to "uncover stories about the natural world we have simply never been able to witness before."

Charlotte Moore, the BBC's controller of TV channels, said: "A decade on from Sir David Attenborough's 'Planet Earth', this new series promises to be an extraordinary experience for our audience. [It's been] filmed over three years across the globe with all the very latest technology."

'Planet Earth II' is set to hit screens later this year.
