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.

The worst and the best that the internet ever did was give everybody a voice.

I realized that if I went snowboarding, you can't think of anything else when you're snowboarding. You can't hesitate or think about anything other than not falling off and breaking your neck. If you want a holiday where you're not gonna think about work and you're not gonna think about anything, snowboarding is the best way to do it. Or skiing, I guess. I don't ski, so I don't know.

I think the jokes would have been a bit broader and a bit more obvious in terms of the day-to-day of country life.

Nira Park, who is my longtime producer and friend - I've know her since we did Spaced, the TV show - she gave me this script the last day of filming The World's End. She said, "Take a look at this. It's filming in London next year, and you might like to look at Jack." I trust Nira implicitly.

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.

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