I just watched “Les Choristes” with my daughters. Emily had watched it at school, dubbed into Chinese. I was unable to find a version with English subtitles that actually matched the dialog. So, we watched the original French version. It didn’t matter. Great movie. Emily, who’s 8 and Charlotte, who’s 6 and I, who’s the wrong side of 50, all thoroughly got it and enjoyed it.
That’s the mark of a great movie; it doesn’t matter what language the characters are speaking, the cinematography and editing can tell the story just fine, “sans langage”.
