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 have never written a book about my life, despite being offered purses of gold. I made 'Boxes' because I wanted to make a sincere depiction of a daughter who has lost her father, or the jealousy one can feel towards a daughter who has become more beautiful than you and whose stepfather starts to take her shopping.

Nothing has ever touched on what fun childhood was. Summer holidays were bliss. We made home movies, with real stories in them. My father had such charm and charisma, and made everything so funny.
