That's what makes characters interesting. If Sherlock [Holmes] had started out being a straightforward man, we wouldn't be talking about him now. If he became one, that would be interesting. But you have to give him somewhere to go, as [Conan] Doyle did.
Mark GatissI am a gay man who loves James Bond films and snooker - all kinds of working-class pursuits.
Mark Gatiss[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.
