IMHO I think that an instead of a potentially "expensive epic war movie" a different approach could be refreshing.
Namely a TV series.
Either one featuring a Luna PD investigation series or one a Freelancer working for the different corporations, exploring the MC universe as the series evolves.
My reasoning for this is that the MC mythos is quite intricate for the average joe (not the fanatics, though...) and gradually exploring and investigating it makes more sense and is more easily grasped. And in that way you could have both good stories to tell and the rich background as a supplement...
