Hi Kate! I’ve just learned how to use a Chrome browser extension called “learning languages” which enables me to export the subtitles and a translation (human generated is best) for an entire show. You can even export it to print, save as a pdf, or read it on Kindle!
Once you have that extension (only works in Chrome) you might also be able to select which language you want to hear for audio. I’ve watched The Crown and Queen’s Gambit in English, and both have Spanish audio options. It’s hit or miss by show.
Disney Plus is loaded with similar features without needing an extension. Worth a free trial!
....and there is a similar extension for Chrome called learning languages on YouTube.
