Choosing a director is like choosing a therapist - you want somebody who is going to be a step or two ahead of you, who can interpret and articulate your intentions better than you can, with the benefit of objectivity. I look for a collaborator who is going to help bring to life, on stage, in three dimensions, what is on the page. I wouldn't want a director who imposes conceits or distrusts the text or who has prejudged the characters.
