BBC, Disney+ Preview Doctor Who Spin-Off War Between Land, Sea

Following the conclusion of Doctor Who's 2025 season, the BBC and Disney+ have released a trailer for the spin-off miniseries The War Between the Land and the Sea, which explores an international crisis triggered by the emergence of the ancient aquatic species known as the Sea Devils. The five-part series, created by Russell T. Davies and Pete McTighe, features UNIT, including returning characters like Kate Lethbridge-Stewart (Jemma Redgrave) and new leads Gugu Mbatha-Raw as Salt, the Sea Devils' vanguard, and Russell Tovey heading the human response. Set with a darker and more adult tone reminiscent of Torchwood: Children of Earth, the show depicts humanity's struggle to survive or coexist with these ancient species without the Doctor's aid. Colin McFarlane reprises his role as General Austin Pierce from Torchwood, further linking the series to the broader Whoniverse. Directed by Dylan Holmes-Williams, the series is anticipated to premiere on BBC and stream internationally on Disney+ in 2026. The storyline promises a politically charged allegory and tense encounters, expanding the Whoniverse with a focus on terrestrial conflict and ancient species awakening.
