As a self-proclaimed Warhammer superfan, Henry Cavill’s commitment to building a faithful universe on screen remains unchanged. Games Workshop CEO Kevin Rountree confirmed in the company’s fiscal report per Variety that Cavill remains heavily involved as executive producer and star alongside executive producer Vertigo.
The biggest news from the report is hiring acclaimed writer/director Mike Flanagan (The Haunting of Hill House, Midnight Mass), who has completed initial project outlines and is officially moving to the scriptwriting phase.
Flanagan’s background working in psychological and gothic horror hints that Amazon’s upcoming Warhammer 40,000 project could lean heavily into eerie, body-horror elements of the 41st millennium.
Is Warhammer 40,000 Live-Action Still in the Works?
Yes, the live-action Warhammer 40,000 project is moving forward smoothly at Amazon Prime Video, though leadership has stressed that building the franchise will require patience from fans.
Games Workshop emphasized that their partnership with Amazon spans both film and television projects, describing it as a multi-year effort that will take time to build properly.
Henry Cavill is not limiting his oversight to live-action. Beyond starring in and executive producing the live-action series, Cavill is also executive producing a standalone, long-form animated Warhammer 40,000 series focusing on the Deathwatch project written by John Orloff (Masters of the Air) and a Warhammer: Age of Sigmar episode for season 2 of Amazon’s Secret Level.
Considering that script and pre-production are actively underway, fans should expect casting details and setting announcements as writing progresses, with production expected to ramp up in the near future. Stay tuned!
