But what does an actor use to create his art? Some would say nothing, but this isn't true. In fact, the actor has the most complicated instrument of all- himself! His experiences, his imagination, his sensitivity. His physical body and his observations. Everything that makes up the sum total of a person's humanity is part of the actor's instrument. As Eleonora Duse once said, "All that I have to offer as an artist is the revelation of my soul."
