It makes a weak man feel like a hero and a strong man feel as if he is immortal, and it removes the last inhibition a killer might feel. You don't have to be close to a man to put a bullet in him. You don't have to have to see his face.
I play a guy who believes he's a king. He's the most common man in the world; in fact his family, like his suits, are just make-up. It's about dysfunctional people and dysfunctional relationships.
