The BBC has unveiled a stunning five-minute trailer for the much-anticipated Blue Planet II.
It comes with an impressive soundtrack by Radiohead and film composer Hans Zimmer - a reworking of Radiohead's song Bloom with Thom Yorke in a new recording of the track, accompanied by the BBC Concert Orchestra.
Yorke said: 'Bloom was inspired by the original Blue Planet series so it's great to be able to come full circle with the song and re-imagine it for this incredible landmark's sequel.'
As with the first series, the narration is by Sir David Attenborough. The seven-part series took four years to complete, with filming taking place across 39 different countries. It will be screened later this year.
