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.

Chris Martin's a good friend of mine. I'm actually Apple's godfather. He's an old friend and we've been mates for quite a few years now.

My worst job was packing animal feed in a warehouse in Gloucestershire when I was a student. It was a very strange environment. It was hung heavy with oat dust, the place was infested with mice, and everyone who worked there was over 60, and I was 18. It was crazy. Apologies to anyone who works in animal-feed packing industry and loves it.

Films that rely on their cast to be funny are often episodic and feel like a series of loosely connected sketches rather than a satisfyingly structured script.
