My dream role would probably be a psycho killer because the whole thing I love about movies is that you get to do things you could never do in real life and that would be my way of vicariously experiencing being a psycho killer. Also it's incredibly romantic.
My role in society or any artist's or poet's role is to try and express what we all feel. Not to tell people how to feel. Not as a preacher not as a leader but as a reflection of us all.
