"Sometimes I have experienced at the start of a film you're very excited and enthusiastic and you've done all your preparation internally and externally and you start the film and it's all go... Then your attention goes somewhere else. Your energy goes into telling the story, so you don't have the same amount of energy to be objective, and that's okay because sometimes you become a subject of the story and you're inside it so much that you don't need to keep on looking on the outside."
