I grew up in a country where movies are rarely dubbed. I was reading the subtitles out loud for my siblings who couldn't read yet for entire movies.

if a movie or TV show had subs we had to take turns reading it out loud

I do this for my wife, because she spends most of a film on her phone.

She's listening to the audio and can mostly follow what's going on by glancing at the screen and reading subtitles every now and then, but if there's a foreign language with subtitles, or a text description (Paris, 11 AM or 10 years later, etc.), she'll miss it and then be completely lost.

I can't tell you how many times I've had to pause a movie and give a quick recap to get her caught up with the plot.
