Jane Birkin

When my father died, my mother came back from being Mrs. Birkin to being Judy Campbell. She was a stunning actress. She came out of her shell. She was herself again: this very independent, funny, intellectual lady - and was able to perform again, which was her life before meeting my father squashed it out.

I colour my hair mousy brown and I wear makeup only on stage. I use Laura Mercier - something called Biscuit, I think. I run one tiny sponge over my face and cover the red blotches. If I've got some rouge, I'll bung it on my mouth and cheeks.

I write for kids because I think the most interesting (and most humorous) stories come from people's childhoods. When I was writing 'Diary of a Wimpy Kid,' I had a blast talking on the phone to my younger brother, Patrick, remembering all of the things that happened to our family when we were growing up.

Working with franchises can be challenging, but at the same time I really did enjoy working on 'Star Wars,' for example, and I have done a lot of 'Dungeons & Dragons' games, but I still enjoy it very much.
