The BBC has announced that Sir David Attenborough will be returning to narrate Blue Planet III.
The original Blue Planet was broadcast across the globe to huge success more than 25 years ago now, and then in 2017, the follow-up Blue Planet II revolutionised our perception of life in the oceans.
But, as the BBC said, this was ‘only the beginning’, as it’s now announced that Sir David Attenborough will provide the narration for the forthcoming Blue Planet III.
This brand-new series is set to build on the groundbreaking legacy of the previous two series by ‘redefining the realm of possibility’ in underwater wildlife filmmaking.
Producers say it will reveal new and untold stories from magical underwater worlds.

“Combining our deeper understanding of the oceans with a whole new generation of camera technology including splash drones, long-term remote underwater cameras and a ‘mini dome’, we can now showcase stunning stories and extraordinary behaviours, previously impossible to film or only recently discovered,” a description for Blue Planet III on the BBC website reads.
Where Blue Planet II exposed the threats to our oceans, Blue Planet III will also explore stories of adaptation and resilience in this changing world, along with stories of hope and recovery.
Speaking ahead of the series’ release, Jack Bootle, who is the BBC’s Head of Specialist Factual Commissioning, commented: “I’m thrilled that David is taking the helm of Blue Planet once again.
“His extraordinary talent for storytelling has shaped the way generations of audiences understand and connect with the natural world, and his voice remains synonymous with the very best of the BBC’s natural history output.
“I’m absolutely delighted that he’ll be once more bringing his unique skill and authority to Blue Planet III.”
