The good thing about being in advertising was a lot of the skills cross over: you have to be accountable for your jokes; you have to tell a story quickly. It's the most expensive filmmaking foot-for-foot in the world, so it does teach you how to use all of the machines and how to think of things in terms of the physical process of capturing the images. And you have to sell your work. You have to walk into whatever it is and stand up in the middle of a conference room with a storyboard in your hand and make people laugh.

You learn to do your best writing on story rather than off story. Very often at the beginning of their careers, writers including me do their best dialogue writing off story - the best lines, the best observations - but they haven't got enough to do with the plot to stay in.

I like to write about love plus an obstacle. Not a really big obstacle; not too serious and not too funny. Just somewhere nicely in between - a combination of the two.

Sometimes you go against what they say because you believe in it anyway.

My job, as I see it, is to give you a window into another world and another story, and then to be as graceful as I can so that you don't feel my work or the editor's work or the lens or the light or anything.

When your characters are not white hats or black hats but something in between, you do have to be very careful about your details. So, that takes a while. I'm not interested in white hats and black hats. I don't think that's how people are in real life.

It's funny when you put music up against picture, and all your preconceptions go away, and you start over. You just realize that that doesn't work at all.
