The BBC has revealed the first glimpse of its forthcoming series, Blue Planet 3, narrated by Sir David Attenborough. The new instalment, which comes a quarter of a century after the original series first aired, was launched with a premiere event in central London on Tuesday, October 7, 2026. Passers-by in Piccadilly Circus experienced a special takeover of the famous screens, which were transformed to show ocean imagery.
Sir David, who celebrated his 100th birthday this year, will narrate the series, promising viewers a more in-depth exploration of marine life. In a recorded message played at the launch, he expressed pride and delight in being part of the project. He reflected on his narration of the first Blue Planet series 25 years ago and noted that the ocean remains an endlessly fascinating place. He stated that the new programmes uncover a wonderful array of underwater life that is more surprising, sophisticated, and important than previously realised.

Ms Thirlwall, known for her role in Little Mix, described Sir David as a true hero and found her involvement in the project incredibly special. She expressed her pride in the song Into The Deep (Seas Cry) and her collaboration with Hans Zimmer and his team. She stated her eagerness for people to hear the song and see the new trailer.
