Selfishness, narcissism, being uncomfortable in your own skin, not feeling connected to the world around you, feeling dislocated from family and youth, having a strange relationship with your childhood - all those things feel really true to me.

I hear the way people talk about the children of famous people. They're not treated very well. The presumptions are usually quite awful. So I tried to establish myself with a couple of movies. After 'Juno' I thought: 'I think I've defined myself enough as my own director that I'd love to work with my father.'

I've been very, very lucky in my career, in my life - from day one. When aspiring directors say, 'What's your advice?' first I say, 'Be born the son of a famous director. It's invaluable.'

It's funny, I can sit through the worst horror film ever made but even a quite good romantic comedy can drive me nuts.

I don't want to make films that give you the answer. If there is a message to my films - and I hope there isn't - it's to be open-minded.
