Though I have no productive worth, I have a certain value as an indestructible quantity.
When you have to play a character that seems to be a relatively decent person and seems to be like yourself, I think the trick in that kind of character, so that you don't become a cliche, is to find where their weaknesses are.
A man's illness is his private territory and, no matter how much he loves you and how close you are, you stay an outsider. You are healthy.
