The thought of filming in London was a big draw because I could stay in my house. I read it, and I was really taken with it because it felt at once very unapologetic for what it was, which is a romantic comedy. But at the same time, a little spiky and a little truthful.

Ultimately, we are all products of the experiences we have and the decisions we make as children, and it remains a peculiar detail of human condition that something as precious as the future is entrusted to us when we possess so little foresight. Perhaps that's what makes hindsight so intriguing. When you're young the future is a blank canvas, but looking back you are always able to see the big picture.

We might not know we are seeking people who best enrich our lives, but somehow on a deep subconscious level we absolutely are. Whether the bond is temporary or permanent, whether it succeeds or fails, fate is simply a configuration of choices that combine with others to shape the relationships that surround us. We cannot choose our family, but we can choose our friends, and we sometimes, before we even meet them.

That's always important to us, is being truthful. Not guessing, not making any assumptions. Just coming at it with knowledge.

Plainly it isn't an exact science, despite it being a complex interaction of micro-decisions and corresponding thought; perhaps it doesn't always work and we pass by some potential soulmates like the proverbial ships in the night, never quite connecting. Then again, perhaps the system is tenacious and continues to run like a computer program on infinite loop, so that if at first you don't meet, you are drawn back together for another try.

There's this thing of you can live in a city and be completely alone, not notice anything going on around you.

Having done Spaced, I can't even remember it being that difficult on Spaced, but we know what the end's going to be like. We know why we're putting in this amount of work, or why a shot might be particularly tricky, because we know that what we do is create a whole package. It's the writing, the performances, and the style of camerawork, that's what we're working toward, and we're prepared for that.
