Acting is the work of imagination. Mesmerizing yourself with your character's objective. Entering a dream, you must stay in the dream. The actor is an entertainer . To make a decision based not on investigating our inner psyche, but on our theatrical sense.
Humanity is the secret in all acting.
Remember people wear a mask . The face they put on to the world. What is really going on inside the person is what you choose. What they pretend is only their mask . However, if you succeed to well in your mask , there is no drama.
