Finding subtitles for non-English parts of a movie

As an example, I have been looking for subtitles for the non-English dialogue in Mission Impossible Rogue Nation. I went to OpenSubtitles.org and entered the search term “English subtitles” for the movie. Many links showed up and I downloaded a few of them; they were all complete subtitles which included the English spoken dialogue. I could find no way of determining if there were any subs for just the non-English dialogue, or a way in which I could request them, or recognize them if they were in fact listed.
Is there some terminology I should be using to find such subs, or to recognize them if they were in fact listed? Is there a better website for finding such subs?
Any help you can offer would be much appreciated!
Answer #1
If the dialog is very famous, you can search for it specifically. If the scene is not important, then your only hope is to find an acculturated subber. Try this site http://subscene.com/subtitles/mission-impossible-5

Answer #3
Thank you both very much for your help. I decided to try to find the same thing for “Ghost Protocol” and succeeded on Subscene, it really helps when a note is given saying “Foreign parts only”! I will be using them from now on. Cheers!
