I have this horrific thing where I'm really bad with names and faces. I have an appalling memory. Someone will come up to me in the street and go, 'Eddie!', and I'll try and give myself time by going into overdrive, 'Hey, hi! Nice to see you!' and start a whole conversation because I can't distinguish between who I know and who I don't.

I'm as voyeuristic and intrigued as the next person as to how celebrities live.

I draw and play the piano badly. But when I’m doing those things, I’m concentrating so hard there’s no room for worry. I find that onstage, too.

Making 'Birdsong,' on the one hand you have how prestigious it is and the reputation of the book, which is something that's an extraordinary piece of work. Sebastian Faulkes is a genius. So you feel that responsibility when you're portraying that character that he's imagined and millions of readers have pictured.

Everything about filmmaking is incredibly weird, and there's nothing natural about watching yourself on the big screen or hearing your voice. It's that same thing that you feel when you watch yourself on a video camera and you hate the sound of your voice - it's that times 800.

As a runner on a film, you are the lowest of the low, and yet you have incredible access to everyone. I can totally imagine that for actors in the middle of a Hollywood bubble, all they really want is a sense of normality, and that gopher can be a tap for that.

They're such hierarchical things, film sets, they're sort of mini societies. Often they're incredibly political places.
