Your first film is always your best film, in a way. There's something about your first film that you never ever get back to, but you should always try. It's that slight sense of not knowing what you're doing, because the technical skills you learn - especially if you have a film that works, that has some kind of success - are beguiling. The temptation is to use them again, and they're not necessarily good storytelling techniques.

My dad was a labourer and my mum had exactly the same job as Noel Gallagher's mum - she was a dinner lady at our local school. Everyone comes over from Ireland and they get the same jobs.

Everybody knows Aaron Sorkin's scripts. There's a huge amount of lines. There's a huge amount of interchange. You gotta do a lot of learning to be able to get it up to pace.

I have this theory that your first film is always your best film in some way. I always try to get back to that moment when you're not relying on things you've done before.

If I was single and did not have kids, I wonder whether if I would try as hard to be patient, to mind how I react to situations. Not saying people who do not have children don't, but in my life and how I fight against doing the things that have positive impact in my life...I think I would find it easier not to practice the principles did I not have children.

It's a nice way to put the focus back on this simple act... if someone creates you.

I always felt it is not good if you feel like you would know how to do something. I've made mistakes of telling people: I know how to do this. And it should feel dangerous. That is the only way to stay alert, to keep the adrenaline running.
