Developments: 2. In late July 2026 Amazon MGM Studios confirmed that its live‑action Warhammer 40K series, first announced in 2022, had moved beyond concept work. Henry Cavill remains the lead actor and an executive producer, while horror filmmaker Mike Flanagan was added as writer, showrunner and executive producer. The partnership now also includes United Artists, with Vertigo Entertainment and Cavill’s own company staying involved. No title, cast list, production schedule or release window has been disclosed, and the project is still in early development. A day later, Games Workshop’s annual report reiterated that Amazon Studios continues developing the series, confirming Flanagan’s role in scripting and Cavill’s ongoing executive‑producer involvement. United Artists remains a partner, and commercial details remain limited. The update signals steady progress but the series remains in the pre‑production phase with no new public milestones announced. ## Timeline ### 2026-07-29: Amazon and Games Workshop Advance Warhammer 40K TV Series with Horror Director Mike Flanagan Amazon and Games Workshop push forward a Warhammer 40K TV series with director Mike Flanagan, while new mobile games including CookieRun: Crumble and Netflix Minigolf debut. 2 sources. https://clstr.news/cluster/amazon-and-games-workshop-advance-warhammer-40k-tv-series-with-horror-director-mike-flanagan ### 2026-07-28: Henry Cavill’s Warhammer 40,000 series adds horror director Mike Flanagan Amazon’s Warhammer 40,000 series starring Henry Cavill adds horror director Mike Flanagan as writer‑showrunner; United Artists, Vertigo and Cavill stay involved, but the project remains years from release. 23 sources. https://clstr.news/cluster/amazons-warhammer-40000-series-adds-writerdirector-mike-flanagan --- Cite as: Warhammer 40K TV series development.
