I'd show some good sounding movies to my over 80yr old parents, but there's not much point seeing as they won't remember them the next day.
I bought them a simple to operate DVD player for Xmas and left a half dozen movies, showed them how to use it (several times over the next month or two) and I'll let you guess how many of those movies they watched to date. Sorry, but no prize for the correct answer.
So if you have elderly parents who can still watch, remember and value a good production, then you (and they) are very fortunate.
