Any recs for books/movies that show class difference in relationship?

I read Alias Grace right after watching Days of Heaven a few days ago, and I think that’s the main cause for my asking this question. I’ve just become very interested in the master/servant sort of dynamic and I’d like to read/see more of it.

As this can be misconstrued, I am definitely NOT looking for something in the form of a Harlequin romance, or some kind of kinky sex porno. It’s mainly… the examination of that class difference that appeals to me, if that makes any sense.

[If you’re not familiar with Alias Grace or Days of Heaven (you are missing out!) then think of something in the vein of Jane Eyre]
