As Games Workshop let slip in a financial report last week, acclaimed horror writer/director Mike Flanagan, fresh off an adaptation of Stephen King’s novel Carrie, will be writing a new live action Warhammer 40,000 series in production at Amazon. Noted Warhammer hunk Henry Cavill is producing the series, but has also reiterated in an Instagram post today that he’ll be in front of the camera, too.

“We have already been working with [Flanagan] to craft the creative, and we’re making some considerable advances in story,” Cavill wrote in an Instagram Reel. “Importantly, some of you have been asking if I will still be starring in the lead role in the live action TV series—rest assured, I most certainly will! Who that character is, however, shall remain a secret for now!”

Warhammer 40K heads who know the series far better than I will surely have their theories—my guesses pretty much tap out with Gregor Eisonhorn, an inquisitor who’s the star of many a Warhammer novel, and Demetrian Titus, the ultramarine in both Space Marine videogames. I’d take Cavill in green makeup playing an ork, though, if only to see how good of a Waaaagh! he can deliver.

While Flanagan is better known for horror than sci-fi, this isn’t the first colossal media property he’s attached his name to. Nearly four years ago he acquired the rights to adapt Stephen King’s Dark Tower book series, and he’s supposedly written the scripts for the first of five planned seasons. But Flanagan has yet to get anyone to sign on to pay for the show, so in the meantime he’s pumped out Netflix series The Fall of the House of Usher, film The Life of Chuck, Amazon miniseries Carrie, and the script for DC’s upcoming Clayface movie.

If there’s an ultramarine chapter focused on prolific screenwriting, Flanagan must be a member. One has to wonder how many “Warhammer 40,000 lore, explained” YouTube videos he’s watched to get up to speed.

“As the fans will know, it’s an absolute monster to wrestle but Mike’s extraordinary talents are helping it take form wonderfully,” Cavill wrote about the live action series on Instagram. “As a combined force and with the good folks at Games Workshop we are all working tirelessly to bring you the best, most Warhammer universe that you could possibly imagine.”
