Sometimes it would be nice to just have some red wine with dinner, but it's not worth the risk. I have a great life, a great situation. Why would I want to risk self-destructive behaviour?

Everyone would talk about their diets and working out and what it made me do was go to craft services where all the food for the cast and crew was and I would eat.

Sometimes, when you're acting, you are so in the moment that you don't even remember what just happened.

I just want to work and be in films that I like, it is so simple. I think from the outside it seems as though as actors, we are picking and choosing our roles, but it isn't like that at all, perhaps unless you are George Clooney. There are not that many movies I would want to be in.

I started doing yoga in my 20s. I did teacher training, that was what I was going to do if acting didn't work out. I started teaching other actors right at the beginning of the yoga craze - people still thought it was a little weird, but a lot of actors I knew were getting into it and didn't want to look foolish in class. So I started teaching them!

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