I think, the movie is all about revenge. A simple interview turns out to be a war of minds and egos. In the end, we know all the deepest secrets of the interviewer, and absolutely nothing about the star. Sienna Miller disguises herself very successfully and misleads Buscemi, making him reveal himself; lose his cocksure appearance and his fake credentials. Surprisingly she does all these with honesty and her honesty beats up the hypocrisy of the other. It makes you keep watching and does not let you lose track of the dialog's in spite of the one shot in one room. Good dialogs, good acting, good movie. Do not play the game with someone who can play better.
