Filming is a witnessing process. You don't try to control it, even though sometimes you wish you could because it can go really, really wrong for you.

If you're filming somebody doing something they really want to do, you're probably not very high on their list of problems to deal with. You see James Carville on the phone - he's like that whether you have a camera or not. He isn't doing it just for you, and that's hard to explain.

To make theater out of real life, you need to catch dialogue when it happens.
