One of the most, in a weird way, encouraging things a director can say to an actor - I know this as an actor - is when you ask them a question, they say, I don't know - 'cause it means there's some space there for you to find out. And it means that there's going to be a process.
I mean, language fascinates me anyway, and different words have different energies and you can change the whole drive of a sentence.
