The long-rumoured Doctor Who spin-off, The War Between the Land and the Sea, is set to start filming in September, it’s been reported.

In January 2023, showrunner Russell T Davies confirmed that spin-offs were part of his plan upon his return to Doctor Who, with reports suggesting the first one will focus on the Sea Devils, the iconic monsters who first faced Jon Pertwee’s Third Doctor and returned in 2022 in a special with Jodie Whittaker’s Thirteenth Doctor.

Deadline has now reported that “shooting will commence in September” on the long-awaited show.
