With such canny self-possession, Johansson is not likely to lose focus as her star rises ever higher. Thus, when the chat shows and magazines and photo-shoots come calling, it's always on her terms. 'You have to know when to say, "No, I have had a really long week, I can't deal with this right now."' Johansson has a reputation for standing firm when it comes to saying, 'No'. Not that she's difficult, just adamant about what is good for her.
