Umm, there are so many people that I've never had one person that I've particularly idolised or I thought "Wow, I want to be just like them." It used to be when I was younger, Julia Roberts, I used to just love her. There is something so appealing about her.

You might be thinking who is this Harry Potter girl? And what is she doing up on stage at the UN. It's a good question and trust me I have been asking myself the same thing. I don't know if I am qualified to be here. All I know is that I care about this problem. And I want to make it better.

I dance a lot and I run and do yoga and play field hockey and tennis. I like to be active. I don't always have time for that stuff, but I do always feel better afterward.

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.

The entertainment industry is pretty nuts, and having had that experience outside of it and going to university has really made a big difference. It's important to me to feel like I have my own life.

It makes me sad to hear girls constantly putting themselves down. We have these unbelievably high expectations of ourselves, when actually we're human beings and our bodies have a function.

I wasn't one of those girls who always dreamed of being an actress. I went to a normal school and then these film auditioners turned up when I was nine. Then I just fell into this whirlwind.
