Interesting comment from Newman on the use of themes:

"It’s not like you say, I need an M theme, I need a Severine theme. Sometimes that has to happen, but for me the creative process doesn’t quite work that way. You find something and that leads to something else. There are elements of story in some of these cues and some of those lead to M because she’s part of the story. By the end you’re going, does Silva have a theme? Is it more of a motif? It’s probably wrong to think that a character needs a melody associated with him or her, but oftentime it does and in the case of Bond it does more often than not."
