All Netflix original content is available for all users in German, French, Italian, and Spanish....
In the past, I would use a VPN in order to trick Netflix into thinking I was in another country so that I could access the content available in that country as a way of studying different languages. Unfortunately, they can now detect this, and using a VPN is no longer allowed. Good news though! Now if you look at the audio and subtitle options on any Netflix original content ( aka the content they produce in house) then you can listen in many different languages! I've found it is a great way to sharpen your ear and improve your language skills while you're lounging!
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
If you go to "Browse" => "Audio&Subtitles", you'll find that Polish is indeed an option :) I'm on the German Netflix and just checked as well. The list of content with Polish audio is pretty limited (much shorter than the French or Spanish ones, with which I'm more familiar), but the list of content with Polish subtitles is really long, so at least you've got something to read I suppose :)
