When you're working on a scene, both in the script phase and also in the moment, you look around and you wait for the lightning bolt to strike you and based on your instincts tell you what the right thing to do is here. And that can result in anything from a change of dialogue to the realisation that what you thought was a dramatic scene should actually have some humour. And maybe if you stage it this way it's funnier, or if you put the camera here it tells a different story. That stuff is kind of everything when you're a director.

That's a phenomenal piece of advice. It's been my compass through the process of making films. But you can really only do that if you're prepared. You can't wing it.

When you start a script you aim to hit a note you know you want to end in general.
