One of the most, in a weird way, encouraging things a director can say to an actor - I know this as an actor - is when you ask them a question, they say, I don't know - 'cause it means there's some space there for you to find out. And it means that there's going to be a process.

Somewhere in there, which always causes my mate Miss Ruby Wax great hilarity, I was offered a biopic of Frank Sinatra. Even I knew that was a bad idea! They'll throw anything at you at certain times. So, you know, to thine own self be true.

Do you know that moment when you paint a landscape as a child and, when you're maybe under seven or something, the sky is just a blue stripe across the top of the paper?

And it's like life changes at that moment and becomes much more complicated and a little bit more boring, as it's rather tedious to fill in the branches.
