BBC confirms David Attenborough to return for Blue Planet III in 2026

by

The highly anticipated Blue Planet III will premiere later this year on BBC One, with the legendary Sir David Attenborough providing narration.

The Blue Planet originally gave viewers a complete look at the world’s oceans 25 years ago, and a second series followed in 2017.

As a long-time fan of the BBC’s nature documentaries, I’m really excited about their new six-part series. From what I understand, it’s aiming to recapture the same sense of awe and discovery that made Blue Planet so special, but take viewers to even more incredible and unexplored places. Basically, expect to be amazed – and maybe learn a thing or two!

This new series takes everything viewers loved about the previous two and pushes the boundaries of underwater filmmaking. It will share incredible, never-before-seen stories from the ocean’s most enchanting environments.

By combining our improved knowledge of the oceans with new camera technology – like drones that can fly near the water’s surface, underwater cameras that record for extended periods, and a small, portable dome – we can now capture incredible footage and reveal amazing animal behaviors that were once impossible to film, or only recently observed.

Following Blue Planet II’s look at the dangers facing our oceans, Blue Planet III will highlight how marine life is adapting and surviving in a changing world, and share inspiring stories of recovery. The new series will explore five major underwater environments: tropical seas, the open ocean, seasonal seas, polar waters, and the deep sea.

In this last of six episodes, we look ahead to the future of our oceans and discuss how to best protect them in a segment called “Future Seas.”

The news was confirmed today (8 May), which also marks Attenborough’s milestone 100th birthday.

Jack Bootle, who commissions factual programs for the BBC, expressed his excitement about David Attenborough returning to lead the next installment of Blue Planet. He praised Attenborough’s remarkable ability to tell stories, noting it has profoundly impacted how people see and appreciate the natural world, and that his narration is a hallmark of the BBC’s high-quality nature documentaries.

Jonny Keeling, who leads the BBC Studios natural history unit, shared his excitement about David Attenborough narrating their new series. He described it as a major production packed with amazing, previously unrecorded animal behavior, filmed in new places, and featuring the latest scientific discoveries, all told through compelling stories. Keeling believes Attenborough’s voice is ideal for inspiring a global audience to appreciate, learn about, and conserve our oceans.
