Being protective is important.

I really don't mind what people assume about me. I really think that my brain is my private thing. I don't need the approval of people. I don't need people to think I'm intelligent. And I'm not that intelligent.

I always say the things you're not supposed to.

I did literature at university, so I had a real relationship with poetry, but they don't make many films about the world of a poet.

My dad's always been a famous actor, so I've grown up with that, and with the lifestyle. In a way, I think I thrive on the insecurity that comes with it. Not in my private life - I like to believe that my friendships and my relationships are strong.

Obviously I have a bit of an awareness because I go to the internet like everybody else but I don't get too involved in the details of those conversations just because it can hurt you if you stumble on something that's not nice.

People are going so far as to kill themselves over the things that happen online.
