I think what people watch television for is the emotional continuity, from episode to episode, and feeling that the experience that they had, four episodes ago, has actually been building to an episode that comes later, and knowing that the characters are growing, as a result of that, and making mistakes, is really, really important to the way people connect to television.

An emotional story is an emotional story no matter how big or small it is.

We were such fans of Sleepy Hollow, in all of its iterations - growing up with the Disney show, and then Tim Burton's and, obviously, the most important being Washington Irving's short story. It evokes and invokes a very specific feeling and tone.

I asked a director once what the secret of it all was, and he said you have to be so prepared that you are willing to throw all your preparation away in the moment when you see something better. 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'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.

By actually taking Sleepy Hollow and the Rip Van Winkle story, and finding the spirit of what was great about both of them and putting them together. So it felt, actually, like one of those ideas that clicked for us, right away, on instinct.
