If you are using a service like UnBlockUs where you can toggle from region to region and access Netflix content from other countries then here is a site for you!
If I can’t find a movie on Canadian Netflix that I want to watch i normally would just toggle to US Netflix on the UnBlockUs Site and see if its there. If that didnt work I MIGHT try UK Netflix.
A bit of hoop jumping but i also discovered there are several sites that list what shows on Netflix on Playing on what region.
http://instantwatcher.com/ and
https://netflixaroundtheworld.com/ for example will tell you where you can find Friends (in 8 different regions).
