I just thought of a faux-Soviet film, like Comrade Detective. But it is a vampire film about supernatural, immortal capitalist Landleeches. You could keep all of the vampire fighting and supernatural tropes but with Bible == Capital Vol. 1, Crucifix == hammer and sickle, garlic == corn

And instead of the more esoteric, like not being able to cross moving water, or enter a house without permission, they have to abide by all of the pre-socialist housing and tenet regulations of that SR. Since Vampires used to represent feudal lords, I think this could be very naturally adopted.
