https://www.warhammer-community.com...r-rogue-inquisitor-tv-stargw-homepage-post-2/ It's being done by Big Light Productions and being run by the guy who did The Man in The High Castle for Amazon. It was only recently announced, so there isn't much info out as of yet. Games Workshop/ Warhammer 40k has been getting more and more popular recently, I guess this was inevitable. I just hope we get to see the full, crushing brutality of the Imperium. It's an incredibly dark and brutal universe, and I don't know if it will work for a mass audience. I run Dark Heresy and my stories got a lot better when I learned the secret to writing 40k, take the most brutal dystopian science fiction I've ever seen, and parody it to 11.
Eisenhorn's probably a good choice, seeing as his novels were popular (and, unlike Gaunt's Ghosts or the Caiphias Cain books, not thinly veiled ports of other material - Sharpe or Flashman, respectively). He's a psyker, so we get the Warp explained along with why unsanctioned psykers are bad news. If they are targeting more than just WH40k fans though, they'll have a hella time explaining the backstory of the setting, especially why humanity has a galaxy-spanning civilisation but folk go round praying to the spirits inside their machines.
