There was a moment of extraordinary humbleness and humility and pride, as well, with my father when he turned to me - and I think it was after I played Salieri in "Amadeus" at university. And he said, You're better than I ever was or ever could be, you should do this for profession. You'd have a good time.

Sherlock being the most prevalent, and they've been really good fun.

I had a very sparse comic upbringing - not because I was being whipped into reading Chekhov and Dickens, but I read Asterix on holidays when I was a kid, and Tin Tin was featured, I remember, for a few years.

I had parents who were working actors, who did really well in their careers, but it was a living. So it was a reality for me growing up; it wasn't a fantasy. It wasn't sitting there going, "I want to be adored." It wasn't that at all. Not to say that the screams of fans aren't a smile-raiser, but that was never the pull for me.

'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.

I'm not an overnight success. I've been doing it for 12 years. It's been lovely and varied so far.

Every job is incredibly different, and I love it because you're picking up skill sets and experiences. It's the university of life.
