You have to accept that the moment you hand a script to a director, even if you've written it as an original script, it becomes his or her movie. That's the way it has to be because the pressures on a director are so staggering and overwhelming that if he or she doesn't have that sort of level of decision making ability, that sort of free reign, the movie simply won't get done. It won't have a vision behind it. It may not be your vision as a screenwriter, but at least it will have a vision.

You're not always right. You're often wrong. But at least you're looking at it as objectively as you can with as much experience as you can in the moment and saying, "Yeah, I think it's funny" or "No, I don't think it's funny yet."

I think everybody has a little rule follower and a little rule breaker in them.

Believe me, you can be in the middle of a beautiful take and the next thing you know you're awash in people crossing the street. You can't even find your actors.

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.

You want to surround yourself with people who are as dedicated to their discipline as you are to yours and let them do what they do.
