I personally never got the gist of Facebook and Twitter.

I'm suffering from stage fright. I don't like making speeches. [...] I'm the kind of introvert actor who likes putting on other people's clothes and pretending to be somebody else, which is completely crazy choice of profession. So, I don't enjoy public speaking and I have every sympathy for anyone who has to do it and doesn't enjoy it.

J.K. Rowling said Bellatrix's role was going to be significant in the last one, when I showed some reluctance in playing a tiny bit part. Up front, they said, 'You're very significant in the last one.' But significant could mean a lot of things. That could just mean a significant plot point. Doesn't necessarily equal big part.

I remember I did think, 'Wouldn't it be nice if Mr Right moved in next door?'

I enjoy those small chats you have when people come up and talk to you about your work. It only involves a few seconds of effort to be nice to those people, and I am very grateful for the kind words that people have taken the trouble to express to me in person.

Usually I'm frustrated when I look at my films and I don't believe that I've made a real transformation beyond my usual sets of gestures and expressions. I still have this nagging feeling that it's me, that I didn't create a unique character.

It's different when you're an actor and playing a part, but when it's just you, you feel immensely vulnerable have strangers prodding and prying.
