How do I prepare role as an Actor?
All the world's a stage and we are but players.
This really needs people that you see from your life. Look at people who perform jobs of authority. Bosses, police, soldiers act in a certain way because of their roles. Solders and police act similarly because of their training but they are taking on the role. Moms and Dads can act roles of Moms and Dads with children on a Sunday afternoon in a park or recreation area. Market places are full of people acting like sellers. Customers act like shoppers. Shopkeepers act like shopkeepers.
Method Actors look for this type of authenticity when they are playing roles. The training of actors encourages them to view people playing roles in real life.
