Two years after acquiring global rights to 'Warhammer 40,000', Amazon MGM Studios has launched the development of a TV series based on the popular game.
That said, I think they should focus on the Guard or even the Arbites. Have Marines just come in like a wrecking ball at some point and DEMOLISH some xenos but mostly tell the story of regular humans.
I'd love a Ciaphas Cain series but it doesn't seem likely.
