Imperial agents expansion is coming...
I can feel it...

If it's gonna be a marine movie, pick the crimson fists. Personally a guard movie with maybe a commissar or commander as the protag sounds more interesting but what do I know, if I was to make a 40k movii/show id make it about the inquisition as a thriller showing insights into inquisitorial investigations and say to day life in the imperium.
