I think going into 'New Moon,' I knew the characters better. I knew the world better and I knew the actors who would be playing these roles. I had a sense of their rhythms and tones. 'Twilight' I was writing in a vacuum. We hadn't cast it yet.
The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.
