The simple fact is that what you see on the screen is pretty much real.

Every person should have their escape route planned. I think everyone has an apocalypse fantasy, what would I do in the event of the end of the world, and we just basically - me and Nick - said what would we do, where would we head?

Suddenly, the world I had scrutinised for so long was all around me, as if I had leaned forward and climbed into the television like Alice through the looking-glass. I had no idea just how deep the rabbit hole would go.

It's hard, really, to make any physical movement that hasn't been done in another film. If you grab someone's hand, it doesn't mean you're referencing other films with grabbing hands...

It's a fun world to exist in, and I relish doing those movies as much as I do the smaller ones. They're always immense fun. I don't know if I am - unless we do a Benji film, I don't think I am an action hero really.

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.

A movie is a creative process from its conception, through its writing, to its execution, to the editing. I think with the best films there is some kind of contribution from one person all the way through that. The best films are made by people who write, direct, and edit, so there's continuity.
