[on performing as a complicated villain in 'Homeland'] It is like reading a foreign book with ten different dictionaries sitting there. When I am playing a villain, I'm not really 'playing a villain' because a villain never looks at himself as a villain. He is being judged by the audience whether he is a villain or a hero. So you just need to be very non-judgmental when you play those types of characters. They are fascinating. That torture and torment and dark side inside us is all just point-of-view. That's what make it dark or light.
