The greatest actors and actresses of the world all have presence. This not only refers to a state of mind that is able to react quickly to unexpected changes and developments in for example a stage production. Actors with a great presence of mind will never let on to an audience that things are not going according to plan. The ordinance will think it is part of the production. Like great statesman many actors and actresses also have the presence of personality. When they enter the room everyone knows that they are there. This is not something that can be learnt at a San Diego Acting Schools. It is a product of a successful career based on extraordinary skill.
