Original Television Soundtrack

The War Between the Land and the Sea showcases how the world reacts when a fearsome and ancient species emerges from the ocean, dramatically revealing themselves to humanity and triggering an international crisis.



Barclay (Russell Tovey) is a low-level UNIT staff member whose ordinary life becomes a world of terror when an ancient species rises from the sea. He becomes humanity’s ambassador when the mysterious Salt (Gugu Mbatha-Raw) emerges from the Tank at a summit on the Thames.

And UNIT, led by Kate Lethbridge-Stewart (Jemma Redgrave), fights for control as humanity faces destruction.

Lorne Balfe, composer said: “Creating the score for The War Between Land and Sea felt like composing at the boundary of two worlds – where the modern day meets the ancient sea. I wanted to draw the audience into a journey of mystery, wonder, and conflict, and I hope every note echoes humanity’s struggle to find balance with forces beyond their understanding.”

The series is produced by Bad Wolf with BBC Studios for the BBC and Disney Branded Television and will launch with a double bill on BBC iPlayer and BBC One in the UK at 8:30pm on Sunday 7 December, and exclusively on Disney+ outside of the UK (where available) in 2026.

The series was created by Doctor Who Showrunner and Executive Producer Russell T Davies, who has written the series with Executive Producer Pete McTighe. In addition, Executive Producers for Bad Wolf are Joel Collins, Julie Gardner, and Jane Tranter. The series is directed by Dylan Holmes Williams.
