I will always have a child in me. That is what Pete Jackson has got, what a lot of the directors I have worked with have. It is about knowing how to have fun and that is something I always want to hold on to.

When I was younger and in primary school, I'd do maybe a film a year, and I had to adapt to being away from everyone for a couple of months.

When I can't get the character out of my head, and I'm in my bedroom and I start to actually act out the scenes that I've read in a script, I think okay, I really want to do this.

I don't feel isolated on a film set. In a way you do because you don't really mix with the outside world; you're just sort of working non-stop for a few months, but you've got so many people around you.

I'm all right, not as good as my mom is. Maybe because I don't have kids.

I like films where there's a relationship between two women. I always think that's lovely to watch on the screen.

I try as best as I can to have a normal life. People recognise you, of course, and that's very strange. But I sort of leave my working life behind when I go home. That's my other world.
