From an interview with filmmaker Whit Stillman:

Your approach to editing is quite striking. Your characters have this very composed manner, but what adds a dose of realism is that you often cut into a scene late and cut out early — so that the conversations are often in medias res, and we get the sense that we really have walked in on life proceeding, like we’re catching a documentary glimpse of it.

Absolutely. It makes things much more interesting if the audience has to fill in some of the blanks. It keeps them on their toes. You get a lot of grief from development people about this: “Well, people won’t understand what’s happening in the scene.” But if you found some way to explain it at the beginning of the scene, then the rest of the scene would be completely boring. Nunnally Johnson, the screenwriter and later producer, would say that the most boring lady at a party is the one who tells you everything. Don’t tell people everything; let them figure it out.
