Here's hoping the poor guy isn't brought into yet another franchise he loves only to see it horribly mismanaged, lol.
I'm cautiously optimistic!
I have a feeling that this won't be the case because he is being brought on as the lead and as an Executive Producer. I am hoping that means he has some creative control to be able to slap the wrists of people and say "No, we aren't doing that!"
I want Henry Cavill to be to Warhammer what Dave Filoni is to Star Wars.
Problem is, personally I want a Guard based story as it's ordinary people in extra ordinary situations. When Marines turn up, as they're bound too sooner or later, they should be absolutely terrifying and scarce. Same with all the Xenos, they should be a completely out of context event. We're used to seeing Orks on the screen in one form or another so I feel they're kind of boring a lot of time.
I could see a Gaunt's Ghost series as being a great point to start. Maybe don't follow the books exactly, but build within the idea of the Sabbat Crusade. Although there are some pretty ridiculous things that happen in those books.
"Oh no, a World Eater!"
*Boom, headshot by Gaunt*
"Oh no, a chaos dreadnought"
*Boom, beslubberin' M'koll*
