Directing Characters

What is directing the characters? How does this work? Why is is a useful technique?

For a moment, the director must forget the character for a moment and interact directly to the actor. The director must find a way for the actor to find the same emotions that are within the same character. The director must face the fear of director and the actor must face their own fear. Having the courage to know that he is able to maintain authority over the actor while also communicating with them is important in the role of directors. Actors needs to give up their desire to control their acting and the directors need to give up their desire to control their directing.
