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.

The trouble with addiction is that you can park the car but you can never switch off the engine or stop yourself from hearing the revs.

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.

The revolution of video had a massive affect. We grew up in a time where suddenly you could own films. Before, they had a theatrical run, and then perhaps they'd come back, or you'd catch them in a retro cinema.

When you meet people that you know from other films - as often happens to me, and as tends to happens to you when you're an actor, you constantly meet people that you've seen in other films. But when it's people who've kind of had a seismic effect on your life, it's quite extraordinary.

It's why I get miffed at all the dashing around in recent zombie films. It completely misses the point; transforms the threat to a straightforward physical danger from the zombies themselves, rather than our own inability to avoid them and these films are about us, not them. There's far more meat on the bones of the latter, far more juicy interpretation to get our teeth into. The first zombie is by comparison thin and one dimensional and ironically, it is down to all the exercise.

When you go into a movie and you're surprised by it - these days with brand recognition being such an important thing and essentially trailers, the way trailers have evolved encouraging people not to see the film unless they've already seen the film which is kind of the paradox of marketing these days anytime that you enjoy genuine sense of wonder and surprise in the movies it's priceless.
