Emotion: The life blood of acting

How many times have you gone to the theater and seen people going through the motions, making big expressive movement with no feelings behind those actions? To make it real, there has to be something more. Real feelings are produced by an actor who has trained sufficiently and when they fill their movement with emotion, it becomes art. I have come to believe that all acting is merely an expression of emotion based on your character's personal ability to control his/her emotions, pitted against obstacles and simmering with conflict of some kind. That is what produces good drama and comedy. Each individual controls emotion differently, It is not enough for the actor to feel emotion, they must also describe that with facial mannerisms and appropriate actions, but it certainly has to be deeply felt by the actor, drawing from personal experience or imagination. It is also no where near enough to simply feel emotion. It has to be acted upon and even dramatised. An actor's movements or actions can be very large in a huge auditorium, but it has to be filled with appropriate emotion or it falls flat. People relate viscerally to emotion deeply felt and this brings empathy and naturalism to your performance.
