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.
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.
