Audio and subtitle options database or resources

[hedliniv]

I have my Russian mother-in-law coming for a 5 week visit and I am trying to prepare to help her stay with us be a little more pleasurable. I would like to pick up some blu-rays that have either Russian audio or at least russian subtitles so that she will have something to watch while she is here. Plus it will be an excuse to pick up a few more titles

Is there a database out there or a list of blu-rays that have Ruissian Audio and or Russian subtitles?

I tried the database search here on this forum however it is only pulling up a few titles and it should pull up many more
(example was Superman Returns was not found)

I would love any suggestions or advise on how to find this!
