War Between Land and Sea: 2025 Viewer Guide

The announcement of "The War Between the Land and the Sea" has ignited the internet in the United Kingdom. Filming has wrapped, the cast is starry, and the monsters are legendary. But this is not just local British news.

This 5-part series represents a massive pivot in global entertainment. It is the first major "Whoniverse" spin-off under the new Disney+ deal.

Why does this matter to a viewer in Ohio, Mumbai, or Sydney? Because it signals the start of a new interconnected sci-fi universe designed to rival Marvel and Star Wars. The Doctor is out. The soldiers are in. The stakes are global.

What is "The War Between the Land and the Sea"?

This is a darker, grounded spin-off of Doctor Who focusing on the military organization UNIT. It features the return of the classic villains, the Sea Devils, who rise from the oceans to wage war on humanity. Starring Russell Tovey and Gugu Mbatha-Raw, it is an eco-thriller devoid of time travel, focusing instead on gritty, planetary defense.

1. The Threat: Who Are the Sea Devils?

If you are not a die-hard "Whovian," you might be confused. Who are these lizard-like creatures?

The Sea Devils are ancient, aquatic cousins of the Silurians. They ruled Earth before humanity evolved. They aren't aliens; they are locals. And they want their planet back.

This series promises to update them for a modern audience. Gone are the rubber suits of the 1970s. Expect high-budget CGI and practical effects that turn these creatures into a genuine horror threat. The showrunner, Russell T Davies, has described this series as "war." It isn't a whimsical adventure. It is a battle for survival.

Pro Tip: You do not need to watch 60 years of Doctor Who to understand this. Just know this: Humans live on land, Sea Devils live in the water, and they both claim ownership of Earth.

2. The Cast & The "Disney Effect"

This is where the show goes global.

In the past, British sci-fi spin-offs often had smaller budgets and niche casts. That era is over. With Disney+ co-producing, the production value has skyrocketed.

• Russell Tovey: Known internationally for Being Human and American Horror Story.
• Gugu Mbatha-Raw: A global star from Loki and The Morning Show.

This casting proves the studio is aiming for prestige TV status. It is designed to sit alongside Andor or Daredevil in your watchlist, not just as a Saturday evening family show.

Pro Tip: Watch Gugu Mbatha-Raw in Loki on Disney+ while you wait. Her role as Ravonna Renslayer gives a great preview of the authoritative, complex energy she will likely bring to this UNIT leadership role.

3. The Genre Shift: Espionage Meets Monsters

This show is reportedly ditching the TARDIS.

Without the Doctor to save the day with a sonic screwdriver, the tension changes. The characters are vulnerable. They have to use bullets, strategy, and politics to survive. This moves the genre from "Space Fantasy" to "Geo-Political Thriller."

Think X-Files meets The Abyss. The focus is on UNIT (Unified Intelligence Taskforce), an international military organization. This allows the story to tackle real-world themes like climate change, ocean pollution, and international borders, all wrapped in a sci-fi metaphor.

Pro Tip: Expect a high body count. In spin-offs like this, "plot armor" doesn't exist. Don't get too attached to the supporting cast.

Frequently Asked Questions (FAQ)
