Star Trek Discovery with Klingon Subtitles on Netflix
The new show Star Trek Discovery has Klingon subtitles on Netflix.
That's all i got to say. Enjoy, Trekkies.
Here's a catalogue of movies/series on Netflix with good subtitles, sorted by language: http://languagelearningwithnetflix.com/catalogue.html
Also, here's a free extension that adds bilingual subs, pop-up dictionary, and improved playback control: https://chrome.google.com/webstore/detail/lln-language-learning-wit/hoombieeljmmljlkjmnheibnpciblicm
Netflix automatically redirects you to their local website. Show is not available on US and Canada's Netflix, therefore "page not found". If you know what you're doing, you can always find it on torrents (illegal).
Yes, it does depend on the region. Sorry about that. Although i checked in with 22 countries, they all have Klingon subtitles.
