I'm from Holland, so I speak Dutch. :) These movies aren't very common here in Holland, it's just that I'm interested in movies, and so I get to see them. It's just as in every other country. And how find them? It just happens. It's pretty logical, because for every movie you see you get five new ones. Also reading books about movies helps, and I also browse through catalogues from Criterion, Masters of Cinema, Blue Underground, BFI etc. I also use What I iWatch (I think the standard language is Dutch, when you register you can change the inferface to English trough options) where a lot of people fill in what movies they have seen, that way you can discover new things as well. The Antonioni movie I posted earlier today was at the Antonioni Retrospective they have in the Hague this month. What language they are in depends on the film, most of the time it is in its original language, but some movies are synchronised. For example a lot of Italian cult movies from the seventies are synchronised in English.
