You can always expect tragedy as well as adventure; that's just how it goes.

When I was seven or eight, I was bought a fantastic book called 'The Movie Treasury of Horror Movies' by Alan G. Frank; it became my bible. It's packed full of the most amazing photos and is still fantastic to look at.

I grew up with low self-esteem. I didn't think I was very pretty. I had glasses, red hair and was generally quite a spod.

Fear is an underrated emotion. And that's why I think it's very dangerous to try and cosset children from it. A healthy scare is as good as as a healthy laugh. In fact, they're two sides of the same coin. There is a desire to shield from the knocks and bumps of reality.
