It took me so many years to move out. I'm definitely a bit of a Peter Pan, reluctant to grow up. It all seemed really nice at home-why change it? Part of me would prefer not to have any responsibility whatsoever.

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'm convinced that whatever state you're in during your pregnancy has a huge influence on the baby's personality - so I hope we haven't produced a little serial killer!

I think my mouth just opens and I spontaneously say things that occur to me.

It feels like a rash. It suddenly seems like I've got a contagion of diseases, I mean awards. But it's nice, it's a nice feeling. It's so weird, because I'm only 46. A lifetime Achievement award... it feels like 'I'm not over yet'. I hope they're not trying to say it's time to stop. I'm only just getting the gist of it.

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.

I'm a very good sleeper.
