There's this brilliantly executed scene from
Elegy. The protagonist, fiftyish, a professor of culture, expert on art, a public intellectual, is having an affair. Well, he isn't married, but he sleeps with two women and both of them think that he's non-comitally comitted to them. So they would be enraged if they found out the existence of another woman. And one night comes the estranged son of the protagonist. He says that he's having an affair and wants to have a man-to-man conversation with his father.
Now, I don't want to give away anything. I've seen directors employ such techniques before where they use an extra to tell his/her story and suddenly that relates to our hero strongly. It's a frequently used tool to explore the moral depths of the protagonist. This scene just nailed it. In fact, I recommed this movie for this piece of writing alone. (And Ben Kingsley's performance.)
PS: I'm half-way through the movie and being blown away, I paused and decided to post about it.
