The live-action Warhammer 40,000 adaptation is moving forward with Mike Flanagan onboard to develop the project, having completed initial outlines and preparing to begin script work, while Henry Cavill remains involved alongside Vertigo.

An episode in Amazon’s Secret Level season 2 will explore the Age of Sigmar universe, expanding Warhammer content on Prime Video and signaling broader adaptation momentum.

Flanagan is anticipated to serve as executive producer, showrunner, writer, and director for the Cavill-led series, marking a second collaboration under his Amazon MGM Studios deal.

Games Workshop reported record revenue and pretax profit for fiscal year 2026, with licensing revenue down due to the absence of a Space Marine 2-type hit.

The project is described as a long-term, multi-year endeavor with contractual limits on commercial detail, underscoring a gradual, broad-based partnership between Games Workshop and Amazon.

Tariffs on Nottingham-made models amounted to £12 million, with £7.8 million reclaimed after a US Supreme Court ruling; next year’s expected tariffs are around £13 million.

Adaptations are expected to span multiple projects over years, not just a single film or show, according to Games Workshop’s financial disclosures.

The development was disclosed in GW’s annual report, signaling a broad, ongoing expansion of a cinematic universe for Warhammer.

Executives caution that premieres are likely years away, with a realistic window around 2028 or 2029 for first releases.

CEO Kevin Rountree frames tariffs as ongoing operating uncertainty and confirms Warhammer adaptations will avoid using AI directly in IP creation to protect IP integrity, while acknowledging indirect AI tools via third-party software.

Momentum around the Warhammer adaptation persists, despite the lengthy development timeline.

GAU (United Artists) is positioned to maintain pace and quality, with timeline specifics still to be determined and expectations for further announcements.
