I’ve aged, but I don’t think I’ve grown up.

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.

Mothers are the heart of any household. I try to spend as much time with my children as I possibly can while also fulfilling my professional duties. It is tricky, but I think I manage it.

I also get fed up with the fact that casting agents and directors have this impression of me as being frail and petite. I find it very patronizing. I'm quite beefy and strong. I was a gymnast in school and I have lots of muscles.

I just want to give you this one piece of advice: if you're standing and you could be sitting, sit. If you're sitting and you could be lying down, lie down.

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

I'm the kind of actor who has ventured into escaping from me.
