David Nicholls

Well, it's so hard for books to take off. You give years of your life to something that probably won't happen, so when it does, it feels a little... unjust.

Read a book at the right age and it will stay with you for life.

As a novelist, I'm incredibly lucky to make a living, but that doesn't mean that I don't lie awake at four o'clock in the morning, worrying.

This might sound really foolish, but when I came to Edinburgh in 1988 I had spent nearly all my life living south of Bristol, and I was just amazed that a city like Edinburgh was actually in the British isles.

I would never complain about 'One Day' taking off, but it made me painfully self-conscious for a long time.

For the best part of my childhood I visited the local library three or four times a week, hunching in the stacks on a foam rubber stool and devouring children's fiction, classics, salacious thrillers, horror and sci-fi, books about cinema and origami and natural history, to the point where my parents encouraged me to read a little less.

When you're reading a book, you're always looking for the natural place to stop. With a movie, you can't really have that sense of it coming momentarily to a halt; there's pressure to keep the momentum up.

David Holdaway was my stage name. I was an actor for about eight years in the '90s. I had to change my name because there was another David Nicholls, and I thought if I changed it to my mother's name, she'd be touched.

I think probably I'm quite sentimental; I like big emotional stories, I like being moved by things, but I think I'm very embarrassed by sentiment. I'm very embarrassed by corniness.

A screenplay is really an instruction manual, and it can be interpreted in any number of ways. The casting, the choice of location, the costumes and make-up, the actors' reading of a line or emphasis of a word, the choice of lens and the pace of the cutting - these are all part of the translation.

When I was an actor, I worked with lots of men who had a bit of success early on, who were very good looking, who suddenly made a bit of money and who felt no embarrassment - and nor should they have done - about having a good time.

I know that for every reader who has lost the habit or can't find the time, there are people who've never enjoyed reading and question the value of literature, either as entertainment or education, or believe that a love of books, and of fiction in particular, is sentimental or frivolous.
