It has been 13 years since Planet Earth, the 11-part documentary series that combined stunning high-definition images of this place we all call home with David Attenborough's inimitable narration. It has been three years since Planet Earth II, the show's six-part sequel, did the same too. A third program, Planet Earth III, is slated to join them in 2022 — but you don't need to wait that long for your next Attenborough-voiced nature doco fix. Four years in the making, Netflix's Our Planet will help fill the gap. Releasing in April, it isn't related to BBC's Planet shows — which also include The Blue Planet and Frozen Planet — but it does still feature Attenborough's informative tones. Across eight episodes, the iconic broadcaster and natural historian will talk viewers through the planet's remaining wilderness areas and their animal inhabitants. The series is made in partnership with the World Wildlife Fund, so expect to see plenty of astonishing and majestic critters. And we do mean plenty. Our Planet was filmed in 50 countries across all the continents of the world, heading everywhere from the remote Arctic wilderness to the South American jungles — and to sprawling African landscapes and the depths of the ocean, as well. In total, it took 600 crew members to shot the series, who helped capture a plethora of never-before-filmed sites over more than 3500 filming days. It's also filmed in ultra high-definition at 4K resolution, so should your TV support it, you'll be in for quite the detailed glimpse at the natural world.
