I found another excellent video essay, this one about the use of Shot Reverse Shot in films directed by the Coen Brothers. I don't think it needs much explanation, but if you are finding these analytical videos interesting I would encourage you to visit the Every Film a Painting YouTube page, from which this comes. All of their videos are well produced and thoughtful.

How do you film a conversation? Most likely, you're going to block the actors, set up the camera, and do shot/reverse shot. But where do you put the camera? What lens do you use? And how do you cut back and forth?
