You know how in fantasy worlds, its all english? Kinda breaks the immersion a bit. I wanna find something where they make it as realistic as possible, and make everything in a fictional language, basically using subtitles as the main way to understand the plot.
Just watch a foreign movie mate. Smth in a language you do not know.
PS. Otherwise look at English ones in the way Tolkien intended. Its translated for you from a fictional language.
Lord of the Rings purports to be a translation of the fictitious Red Book of Westmarch, with the English language in the translation representing the Westron of the original, translators need to imitate the complex interplay between English and non-English (Elvish) nomenclature in the book.
