The director's main responsibility -- and prerogative -- is telling the story. This means finding a structure to the script and setting up the events so that they are at once surprising and inevitable. You give the actor direction in order that the actor's actions and interactions illuminate and create those events. The actor has a responsibility -- and prerogative -- to create truthful behavior while following direction and fulfilling the requirements of the script. Actor and director must respect each other's creative territory.
