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 the whole concept of being ‘sexy’ embarrassing and confusing.

I threw my 20th birthday party at Brown, and I didn't even have to say to anyone not to put pictures on Facebook. Not a single picture went up. That was when I knew I'd found a solid group of friends, and I felt like I belonged.

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.

When I started dating I had this kind of Romeo and Juliet, fateful, romantic idea about love. It was almost that you were a victim - that there was a lot of pain involved and that was how it should be. Shakespeare said the course of true love never did run smooth and I had a sense it had to be painful. It was such a revelation to realise it shouldn't be that way and you get to choose who you love and who you give your heart to.

What I find difficult about photo shoots is the line between playing a character - you're being asked by the photographer to take on a role like you would in a movie - and being a fancier version of yourself. It's about finding that line between being spontaneous and open to direction, but also trying to explain to photographers that the "me" is often taken out of context because it has all of this other stuff attached to it.

Whether you are a woman on a tea plantation in Kenya, or a stockbroker on Wall Street, or a Hollywood actress, no one is being paid equally.
