What To Expect From The War Between The Land And The Sea
In The War Between the Land and the Sea, Russell Tovey (Being Human, Arrowverse, American History Story: NYC) plays Barclay, a low-level UNIT staffer who's thrown into the middle of a brewing conflict between mankind and the returning Sea Devils.
On the other side of that, Gugu Mbatha-Raw (The Morning Show, Loki, Surface) stars as Salt, a member of the Sea Devils whose mission just so happens to revolve around Barclay. Of course, long-time Doctor Who fans will remember Mbatha-Raw for a handful of appearances as Tish Jones back in the David Tennant years of the Doctor.
For UNIT, Jemma Redgrave reprises her Kate Lethbridge-Stewart role as the organisation does its utmost to stop the destruction of humanity, and we've also got Ruth Madeley, Colin McFarlane, and Alexander Devrient back as Shirley Bingham, General Austin Pierce, and Colonel Christofer Ibrahim, respectively.
As per creator Russell T Davies, the aim is for The War Between the Land and the Sea to give Whovians a nice slice of weekly Who action, with the entire five-episode series then seen as an ideal binge watch for the holiday season.
The official synopsis for The War Between the Land and the Sea reads:
"When a fearsome and ancient species emerges from the ocean, dramatically revealing themselves to humanity, an international crisis is triggered. With the entire population at risk, UNIT step into action as the land and sea wage war."
