We enjoyed such amazing success on Sex and the City. You don't expect success on that level, it was such a big deal, and it was so intense and wonderful that it is hard for anything else to live up to it, quite frankly. So now I just try to have fun and work with interesting people. I think that there is a perception that certain films won't be popular. So it was great that The Devil Wears Prada did really well.

I think that when you are famous, it can work against you, people have preconceptions about your image.

I'm not really much of a shopper. I have to say that I'd definitely prefer good sex. What makes good sex? Oh my god. I think you need to feel free and you have to really trust the other person. And you have to have that strange, mysterious chemical connection.

I think fashion can have a very negative impact on young people who feel they have to be thin. I am not part of that trend. There is so much pressure on teenage girls.

Danny DeVito knows about the business from many different perspectives, because he is a producer and director as well as an actor. At one point we were on the set late at night and he said: 'come here I want to brush your hair'. I said 'ok'. He sat there brushing my hair and told me that his job before becoming an actor was as a hair stylist in Manhattan. I said "what?" But it is true.

I'd wanted to be an actress my whole life, that was my goal, that was all I cared about.

Holidays do bring out the craziness in everyone. This time of year tends to being out the insanity in otherwise normal people.
