BBC America will produce sequels for two of its successful nature-themed franchises, Planet Earth and Frozen Planet.

The eight-episode Planet Earth III, set to air in 2022, will feature new technology -- including robotic cameras, stabilized rigs and deep submersibles -- to take viewers from the highest mountains to the deepest oceans, from the darkest caves to the hottest deserts, according to the network.

In Frozen Planet II, the six-part series will continue to explore snowy forests and frozen Arctic oceans around the world and the animals that live there, the network said.

“One of the things we’re most proud of at BBC America is that we’ve established the network as the U.S. destination for the very best nature programming on the planet, from the BBC’s award-winning natural history unit,” said Sarah Barnett, President, Entertainment Networks, for AMC Networks in a statement. “We are delighted to renew our successful partnership with BBC Studios, and to continue to co-produce these groundbreaking series. To bring together audiences for this kind of transcendent event television is a true privilege, we couldn’t be happier to continue to do this for the next five years.” 

AMC Networks said Planet Earth: Blue Planet II, the latest installment to the David Attenborough-hosted Planet Earth series, will premiere on Saturday, Jan. 20 (9/8c), on BBC America, AMC, IFC, WE tv and SundanceTV before settling into Saturday nights on BBCA. The simulcast plan was previously announced.

Says BBCA: Planet Earth: Blue Planet II takes viewers on a revelatory and magical journey into the mesmerizing world of our oceans – the most undiscovered place on our planet. Our oceans are by turn tempestuous and serene, exquisitely beautiful and bleakly forbidding. They cover 70% of the Earth’s surface and hold 97% of all the water in the world. There is more life in the deep sea than anywhere else on Earth. It is said we know more about the surface of Mars than the depths of our own planet. Our final frontier is the deep ocean – Earth's ‘inner space.’

AMC Networks COO Ed Carroll said in a release: “Planet Earth: Blue Planet II is rare, event television, an extraordinary series we are so proud to launch as a premiere simulcast across all five of our national networks. AMC Networks prides itself on being a premiere destination for extraordinary storytelling in all of its forms, and this remarkable exploration of our natural world from the BBC is storytelling at its finest.”

BBC America president Sarah Barnett said in the release: “This next chapter in BBC America’s nature programming franchise is more incredible than anything yet seen, complete with heart-pounding exploration and incredible cinematography. The experience is a magical and transcendent trip into unexplored worlds.”

More than four years in production, the Planet Earth: Blue Planet II teams mounted 125 expeditions, visited 39 countries, and filmed on every continent and across every ocean. They spent over 6,000 hours diving underwater, filming everywhere from familiar shores to the deepest seas, per BBCA. Presented by Attenborough, the series is made by BBC Studios’ Natural History Unit, co-produced with BBC America, Tencent, WDR, France Télévisions and CCTV9 in partnership with The Open University. 

Netflix has partnered with Silverback Films to produce a new eight-part natural history series to debut in 2019.

The series, Our Planet, will take viewers into wilderness areas, remote forests and deep ocean areas never before filmed, the OTT service said. Silverback Films was the driving force behind the 2006 Planet Earth project as well as BBC shows Frozen Planet and Blue Planet for the BBC, as well as the Disneynature films Earth, Bears, African Cats and Chimpanzee.

“Netflix is proud to be the global home for perhaps Silverback’s most ambitious project to date,” said Lisa Nishimura, Vice President, Netflix Original Documentaries in a statement. “The Planet projects have enjoyed great success on Netflix and have helped launch new technologies for viewing at home. We think watching Our Planet, fully on demand in 4K will be an unforgettable experience for our members.”
