Sir David Attenborough to Narrate BBC's Blue Planet III

The British Broadcasting Corporation (BBC) announced a six-part hour-long natural-history series, *Blue Planet III*, to air on BBC One and stream on iPlayer. Sir David Attenborough, narrator of *The Blue Planet* (2001) and *Blue Planet II* (2017), will provide the voice.

The original *The Blue Planet* gave the first comprehensive view of marine life. *Blue Planet II* sparked the “Blue Planet effect,” boosting marine-biology university applications and raising concern over single-use plastics. *Blue Planet III* aims to extend that legacy with new scientific discoveries and footage.

BBC Studios’ Natural History Unit will use splash drones, long-term remote underwater cameras, and a ‘mini dome’ rig to capture behaviours previously unseen, expanding possibilities in underwater wildlife filmmaking.
