I defy anybody to not look cool with the guns. My granny could look cool doing that!

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.

I've only played two sort-of slackers, in Spaced and in Shaun Of The Dead. They're different people, but they have the same kind of everyman quality, particularly as a twentysomething.

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.

I used to lie in bed in my flat and imagine what would happen if there was a zombie attack.

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.

When men write women, they tend to write women the way they want women to be, or the way they resent women for being. They don't really - they seldom nail it. It takes a woman to write a really good female character. I like that.
