I speak english well enough to not need translation/subs when watching obscure American movies :)
(Since you talked about foreign movie, I assume American movies count as foreign)
That would have to be absurdly obscure. Case in point: even Hirokazu Koreeda’s “Distance” has translations available in most languages. I can’t even find art films that lack translations.
Lots of Chinese stuff that lack subs. Often it’s only available on bilibili, too.
I mean, even if something has no subs I think if it was important enough I would watch it anyway.
letermagô. That’s it.
