As actors, it is our job, our responsibility to observe human behavior. We do this to understand what it reveals about people and relationships, because it gives us information that we can use, another frame of reference for an idea or character or relationship. Imitation may be where we start but it can’t be where we end up. To inhabit the character fully we need to scratch the surface of physicality and behavior to understand what is going on underneath it and thus build the full scope of a complex human being.
