International affairs is very much run like the mafia. The godfather does not accept disobedience, even from a small storekeeper who doesn't pay his protection money. You have to have obedience; otherwise, the idea can spread that you don't have to listen to the orders, and it can spread to important places.
Acting is about giving yourself away, like the U2 song 'With or Without You.' You just don't stay behind a character and make people laugh or cry. At some point you have to take off that mask, and when you do, you're a human being, not just an actor. After all, I'm Catherine the person first. You share that.
