Learn more about the actors behind these new ‘Doctor Who’ characters and find out where you’ve seen them before
Doctor Who has been around for a long time and that universe (or Whoniverse) is going absolutely nowhere. While the Doctor Who series is ongoing and set to release more seasons in the future, spinoffs are still in the works where other characters from the Whoniverse will make an appearance.
An upcoming series based in the Whoniverse titled The War Between the Land and the Sea is set to release sometime in 2026. The official plotline 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 steps into action as the land and sea wage war.”
Meet the stars of the new spinoff and find out which have appeared in other Doctor Who series before!

Thoughts on The War Between the Land and the Sea: “He’s [Barclay] someone who works in the offices and books people’s taxis, but by some series of events, he ends up becoming a very important figure in the world, and having to understand that role and what that entails…And, in true Doctor Who [fashion, he’s] saving the planet. It was just a total joy to play this everyman who’s the sort of a guy that’s drifted into his late 30s, early 40s and, unbeknownst to him, just thought, ‘This is what life was going to be.’”
