Speaking as a Warhammer fan who's had to defend his choice of hobby more than once, it is a very problematic topic. Part of the problem is that Warhammer 40k, like Judge Dredd, was originally satirical - a black comedy piss-take of authoritarianism as understood by the British in the 80s.burnout02urza said:I'm beginning to wonder how a Warhammer 40K movie would do in the current climate, however.
But, like with Dredd, as time passed it started to play the ridiculous fascist aspects straight, partly because satire is difficult and partly because that's what the fans liked, and it's really awkward trying to explain to a college-aged lady who you'd like to impress that liking a fictional setting where Catholic Space Nazis are the good guys doesn't mean that you like fascism or totalitarianism; you just think it's cool. Kind of like the kids trying to explain to their parents that they don't listen to death metal because they want to worship Satan, but because listening to it makes them feel better.
As for the plausibility of a Marvel-style 40k film franchise - it'll never happen for a number of practical reasons; firstly, the money required means that it would almost certainly need a big-budget production company, and GW is about as willing to license its IP as a dog is willing to give up your shoes once he's got his teeth in them. Secondly, despite its memetic popularity online, it's still very much a niche market; not everyone has the patience or money to collect Warhammer, and the company's own policies have been driving away their most dedicated fans for the past decade or more.
In my dreams I picture a future where Warhammer has evolved into something like Skylanders, so that the physical models have a virtual counterpart that lets anyone play online in community tournaments with procedurally generated maps. GW would still make money off of model sales - a Space Marine model would equal a Space Marine in the game - and people could still paint and display the models - even maintaining an online showcase - but the simple logistics of arranging a game would be dramatically simplified. No need to free up a table for most of the afternoon, decorate it with lavish and expensive terrain pieces, and then find one or more friends also willing to put in the same amount of money and time just in order to get a single game done. Maybe if the hobby reaches that state, it'll hit the pop cultural critical mass required to pull off a multi-film franchise like the Marvel films.
Pity GW will never, ever do it
