So, I once watched The Lighthouse together with my then girlfriend remotely, being in a long distance relationship at the time. We used the same file, started at the same time and were in chat together.
The audio codec of this (of course 100% legal) file for some reason did not work with my VLC player properly. There were no voices. But it also wasn't just complete silence, some music and subtle, surreal sound effects came through. None of this was happening for my ex, btw, even though we had the same file.
Talking about the movie in chat and afterwards was fascinating, I only then realised it was, in fact, not a masterful, purposeful, stylistic choice: A major production not just in black and white, but as a silent movie. I also was able to get the essential things that happened and the important plot points, so that is also another point very much in favour of the film.
