I've often been told that I'm a bit strange. I hear that pretty regularly, but it is not how I see myself.

I'm never anywhere for more than three weeks.

I didn’t want people to decide what I was going to wear and what I was going to look like and how I should behave.

Actresses are so spoilt - we have someone who does our hair for us on set, so we don't know how to do it ourselves in real life. I know how to wash my hair and brush my teeth, but that's about it!

To me, performing means trying to do the most you can with the partner in front of you, with the story you're telling. There are actors who have carried me, who have brought me elsewhere or with them.

I had a grungy period and looked like a tramp for a very long time - my mum really hated it! I destroyed her entire '70s wardrobe by putting studs into everything - I thought I was really cool. But it's good to experiment - I even had dreadlocks at one point.

An actor alone is a bit naked. Like when you do something in front of your mirror, you're usually really bad, because you're looking at yourself.
