With any part you play, there is a certain amount of yourself in it. There has to be, otherwise it's just not acting. It's lying.
“I'm not angry, I'm not an angry person, but I do sometimes like playing with the perception of anger, as in pretending that I'm more angry than I actually am, and sometimes it works quite well.”
“Tomorrow is the day when idlers work, and fools reform, and mortal men lay hold on heaven.”
