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.

Believe in yourself and go for it

If I were in the director's chair, I would cast [Geena Davis] in something awesome every six months if I had the choice.

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. I had lots of times when I thought: 'Woah, woah, hang on - I'm not completely sure about this.' I didn't come from a background of films. I didn't even really ever watch films. The fact is, my parents weren't into that stuff, and neither was I.

Becoming yourself is really hard and confusing, and it's a process. I was completely the eager beaver in school, I was the girl in the front of the class who was the first person to put her hand up, and it's often not cool to be the person that puts themself out there, and I've often gotten teased mercilessly, but I found that ultimately if you truly pour your heart into what you believe in - even if it makes you vulnerable - amazing things can and will happen.

Oh, I think Rupert's gorgeous. He is, he's totally gorgeous! Very handsome, very handsome indeed.

Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life.
