In a way, putting actors deep into this sort of complicated universe frees them from thinking about who they should be. They just are somebody.

I'm just thinking of 2001, which I think is the most expensive independent film ever made - which is great, someday I hope I will do one. But I know the parameters when I got onto this project - I have to take care of everyone, make sure that they are all on board, and this process interests me.

The idea that competition is pointless is really something that speaks to me, especially in America where competition is really prominent and very overwhelming, and it doesn't bring the best out in you because what's going to push you is to bring others down.

I learned to drive when I was 35. I'm driving like an old lady and very close to the wheel. I don't take many risks, and when people yell at me I say 'sorry, sorry, sorry!' I don't have road rage yet.

That's what the internet is: it's like bombarding your eyeballs with these myriad blinking colour lights. It's like trying to watch a movie on your phone in the middle of Times Square.

I like actors who just are who they are, with a little bit of qualification to adapt to their character. But mostly they just use their own personality to embody the character.

My grandfather lived across the garden from us, and in his attic he had a lot of radios, appliances and inventions that he had made over 50 years, such as a keyboard called a clavioline, which can be heard on some Beatles songs - it was popular in the 60s. So we had all that at home.
