Hermione is so close to who I am as a person that I've never really had to research a role. I'm literally rediscovering what it means to be an actress.

I paint and I draw and I write and I do other things too, and recently some people at school were asking if I'd ever publish any of my work. But I almost feel like I would have to publish it under another name because there's a definition of me out there that feels kind of stuck in the moment when it was formed.

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.

The most embarrassing one is that I had no idea - and please excuse me - that you guys call a condom a rubber. My version of a rubber is an eraser. I've done that - very loudly asked for a rubber and people have given me strange looks. That was embarrassing!

I find it easier to cry than I do to laugh convincingly. It's incredibly hard to pull off a laugh that feels natural take after take after take, that feels real. You can tell a fake laugh the minute you hear it, and that's something I really struggle with more than producing tears.

There's a Theodore Roosevelt speech about the importance of being in the arena, whether you fail or you succeed, or you make a complete idiot of yourself, as long as you're doing the best with what you have, using whatever knowledge you have to bring to the table at that moment. And you continue to keep learning. I think my mistakes have made me much stronger. It's nice to know that things don't ultimately break you; that you need to go there to know.

There's nothing wrong with being afraid. It's not the absence of fear, it's overcoming it. Sometimes you've got to blast through and have faith.
