The War Between the Land and the Sea is ready to be waged, now that filming is underway on the new Doctor Who spinoff announced at this summer’s San Diego Comic-Con.

The five-part spinoff that stars Russell Tovey ( Quantico ) and Gugu Mbatha-Raw ( Loki ) alongside franchise vets Jemma Redgrave (as Kate Lethbridge-Stewart) and Alexander Devrient (as Colonel Ibrahim).

Mbatha-Raw made her franchise debut in a series of spring 2007 Doctor Who episodes, playing Martha Jones’ sister Letitia aka Tish, while Tovey in April 2008 guested as MIdshipman Frame — but spinoff creator Russell T Davies has made clear they’re playing new roles: “This is not Midshipman Frame teaming up with Tish Jones.”

The full cast revealed in the photo above also includes Ruth Madeley, reprising role from last winter’s 60th anniversary specials as UNIT Scientific Advisor Shirley-Anne Bingham, and Colin McFarlane, reprising his role as General Austin Pierce from Torchwood: Children of Earth .

The title of this new offshoot was teased in the May Doctor Who episode 73 Yards , where Fifteen observed, “The rocks and the water, it never ends — the war between the land and the sea”.

The premise: “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 steps into action as the land and sea wage war.”

Said species is in fact the Sea Devils, classic Doctor Who villains that made their first splash in 1972.

The Sea Devils are “a race that lives beneath the oceans. They wake up, and they see the state of the oceans, that we have put it in,” Russell previewed. “We have wrecked the place, and it is war, war on an epic scale.”

Current Doctor Who showrunner Davies created the spinoff with penned it with Pete McTighe ( A Discovery of Witche s, Doctor Who ). Dylan Holmes-Williams (director of Doctor Who ‘s “73 Yards” and “Dot and Bubble”) will direct.

The spinoff will air exclusively on Disney+ where available, and BBC One and BBC iPlayer in the UK.
