Acting is about using all five senses, Sight, Sound, Touching, Tasting, and Smelling. In other words what is Richie Seeing, Feeling when he is inside the Frat Party, what is he smelling, is it Weed, Alcohol,etc. What is Richie Tasting, is he eating anything, What is he seeing, A lot of females, drinking, dancing, Is Richie hearing a lot of music, talking, laughing chatter,etc. This will help the actor choose how he talks, walks, listens, and act, if it is loud, he most likely will be speaking louder than normal trying to speak over the loud voices and laughter that is taking place, If he smelling food, he may be catching the munchies and getting hungry, all of this helps the actor prepare himself for the role and the scene. These are examples of how you can develop the WHO ARE YOU Lesson in a particular scene.
