Sorry for the late reply, been sorting out my home Instance.
Looking over the cinematic landscape, we are a bit lacking in regional film communities as a whole.
Apart from this, as best as I can find, there's only [email protected], which I also started.
I only started this because I'd started r/categoryiii on Reddit but that was slotting into a large structure:
- r/AsianCinema
- r/ChineseCinema - stated as being for Chinese, HK and Taiwanese films, which is controversial
- r/KungfuCinema
- r/JapaneseCinema
- r/IndianCinema
- r/TamilCinema
- r/FrenchCinema
- r/CinemaBrasil
- r/PersianCinema
- r/AfricanCinema
And on and on.
However, to the best of my knowledge, we have none of that.
So I'd suggest starting at c/AsianCinema and potentially EuropeanCinema,.AfricanCinema, etc and then perhaps pin a post about ways the wiser regional cinema communities could expand.
edit: I was going to suggest lemmy.film would be a logical home but that instance seems to be gone. Pity.
