[Toby Jones] is completely different. It's a completely different character. He's the darkest villain we've had. There was always something charming and engaging about Moriarty. There was something fascinating and actually amoral, rather than immoral, about Charles Augustus Magnussen. This guy is the purest evil. Sherlock [Holmes] is actually appalled by him.

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.

It's a cliche, but it's true that all the fun lies in baddies, grotesques and comic roles.

If not exactly raging against the dying of the light, I was at least a little cross with it.

Slightly forgettable movies can sometimes make great musicals.

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.

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.
