May I make a suggestion, hoping it is not an impertinence? Write it down: write down what you feel. It is sometimes a wonderful help in misery.
But things such as 'Harry Potter', all I can do is shape my character, seek the director's approval on that, and basically take it from there. Professor Flitwick in 'Harry Potter', I kind of defined how I saw him from reading the book, and luckily that matched up with the director's vision.
My wife comes from a foodie family so I've been indoctrinated into that. I had sweetbreads the other night, and I have to say, not my favorite thing in the world You're eating a gland.
