Actually, I think I'm part of the last generation to grow up believing in magic and fairies and believing I had powers - you know, lying on the ground and trying to have my spirit leave my body - which never happened; still working on that bit.

It's a bit like school camp, shooting a film. Everyone's on heat. It's a strange energy. It's full of adrenalin. I funnel my excess energy in funny little ways. I do a lot of dancing in my trailer. I love music.

I've spent half my life on planes. I have a lot of love for New Zealand, though. That is where the really arty, whimsical side of the family resided - in Hobbitland.

I deliberately went to boarding school. It was my choice. My mum was abroad and I wanted to wean myself off being dependent. It was a very important time for me to be able to create my own individual, independent life; just as a way of growing up.

I grew up on film sets but more around the process of making films. I saw a lot of the editing process and the writing process, which takes years. That really affected me growing up, that side of it.

I was 13 when I first saw my mum's films. There were these boys who said to me, 'Your mum makes sexy films,' and I said, 'She doesn't.' Then I watched them and my mum makes sexy films! I'm a huge fan of my mum.

As for the Kristen Stewart comparisons, I just don't think that's fair. I thought she was great in On The Road and Into The Wild. But she's got enough people scrutinising her without me adding my take.
