I could be 100 years old and in my rocker, but I'll still be very proud that I was part of the 'Harry Potter' films.

People sometimes talk about me as being a brand, having a strategy and whatever else. I wish. Seriously. I wish I had it together enough to have a strategy. But it's so instinctual. It usually comes down to two things: the person I'm working with - the director is really important to me - and a line in a script.

I HAVE REALIZED THAT FIGHTING FOR WOMEN'S RIGHTS HAS TOO OFTEN BECOME SYNONYMOUS WITH MAN-HATING. IF THERE IS ONE THING I KNOW FOR CERTAIN, IT IS THAT THIS HAS TO STOP.

I went from being totally unknown and never acting professionally to being in a major movie and being very famous. It all happened so quickly, I didn't have any time to work things out. It's been pretty scary at times.

The character is everything that I felt really strongly against - she's superficial, materialistic, vain, amoral. She's all of these things, and I realised that I really hated her. How do you play someone that you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be.

And I always keep cards people send me. I have a whole wall covered with them.

I've got about eight pairs of shoes, and that's it.
