Blue Planet III Extended Trailer Offers First Look at Six-Part Ocean Series

BBC America and BBC Studios have released the first extended trailer for Blue Planet III, returning the landmark natural-history franchise to the ocean 25 years after the original series. Sir David Attenborough narrates the six-part production from the BBC Studios Natural History Unit.

The trailer presents marine animals and deep-water environments that will feature across six hour-long episodes. The series is co-produced with BBC America, ZDF and France Télévisions in association with Skai Greece. BBC America and AMC+ have confirmed a North American premiere in 2027, while regional broadcasters and dates may differ.

Attenborough recorded the narration in his centennial year. The trailer is accompanied by Into the Deep (Seas Cry), created by JADE, Hans Zimmer and Bleeding Fingers Music, which is also producing the original score.

For divers and underwater filmmakers, a new Blue Planet series matters because productions at this scale shape public expectations about marine wildlife, imaging and conservation. Spectacular sequences can also conceal the long fieldwork, behavioral research, specialist camera systems and safety planning required to make them. Detailed production notes should be used before attributing any sequence to scuba divers, rebreathers, submersibles, ROVs or remotely operated cameras.

The series can provide a bridge between mass-audience ocean storytelling and the observations divers make at local sites. NBM coverage should distinguish confirmed animal behavior and conservation findings from dramatic trailer editing, and should revisit the series when episode guides and behind-the-scenes production information are released.
