An actor must make his needs (goals, wants, objectives) so strong that he is willing to interfere with the other actor in order to get what he needs. Interfering means getting in their way so that what you want is stronger than what they want.
Michael ShurtleffCompetition [in a scene] is healthy. Competition is life. Yet most actors refuse to acknowledge this. They don't want to compete. They want to get along. And they are therefore not first-rate actors.
Michael ShurtleffHumor [in a scene] is not jokes. It is that attitude toward being alive without which you would long ago have jumped off the 59th Street Bridge.
Michael ShurtleffAn actor is looking for conflict. Conflict is what creates drama. We are taught to avoid trouble [so] actors don't realize they must go looking for it. Plays are written about...the extraordinary, the unusual, the climaxes. The more conflict actors find, the more interesting the performance.
