The goal to being a good actor is stepping outside yourself. Walking in the skin and shoes of someone else. The actors and actresses who are best at it are the ones who utterly convince you they are someone else every time you see them on-screen. Then, you have the actors who only play themselves. You know the kind I am talking about. They are the actors who seem like they walked on stage during a movie and just started saying stuff they would have said in real life. While it can work in some instances, most of the time it is grating and completely pulls the audience out of the movie they are watching.
