Things get pretty gruesome in the pitch-black universe of Warhammer 40,000. That’s why it only makes sense that Mike Flanagan is now getting involved in Henry Cavill’s series for Amazon.
Things have been very quiet lately regarding Henry Cavill’s planned Warhammer 40,000 TV series for Amazon. Too quiet. But don’t worry—license holder Games Workshop has finally provided an update (viaIGN), according to which the project is finally moving forward.
Here’s the most important information at a glance:
- The basic concept is in place,and now they plan to
start
working on the script soon. - CEO Kevin Rountree confirms thatHenry Cavill remains involvedin the project.
- In addition, Mike Flanagan—a true horror expert—is now working on the film adaptation of Warhammer 40k, not only as a producer but also as a screenwriter.
Why Mike Flanagan’s Involvement Is Causing a Stir
Mike Flanagan’s involvement is certainly an exciting development!After all, as we all know, the Warhammer 40,000 universe is pretty rough and grim. We’re talking about a dystopian scenario in which genetically engineered super-soldiers wage a suicidal war against cosmic deities.
So it certainly makes sense that the driving force behind horror projects likeThe Haunting of Hill House,Stephen King’s Doctor Sleep,Midnight Mass,andThe Fall of the House of Usheris now getting involved in Henry Cavill’s series.
Flanagan already has close ties to Amazon:Most recently, the film and series creator signed an exclusive deal that will also result in a remake ofStephen King’s *Carrie*.
When might Henry Cavill’s Warhammer 40k series be released?
But even regardless of Flanagan’s involvement in Warhammer 40,000, this is welcome news: After Amazon and Games Workshop finally reached an agreement in late 2024, production on the series is now finally getting underway.
Keep in mind, however, that it will likely still take a few more years before Warhammer 40k arrives on Prime Video as a series. The script must first be written before the casting process and then filming can begin. So be prepared for a wait of at least two to three years.
