Doctor Strange is an origin story so there's a certain room for me improving as well as the character improving.

'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.

It's great for the people who supported me early on to see the success I'm enjoying.

I'm always playing characters with intellects profoundly superior to mine. That's great fun, even though it's as much a fantasy for me as for the people watching me.

I'm still very sensitive and wary of people recognising me The only thing that really annoys me is people trying to surreptitiously take a photo on their phone without asking. I feel it's cowardly and a bit pathetic. Just ask me if you really want me to have a photograph with you.

I'm a Prince of Wales Trust ambassador, so I'm all about giving youth an education, a voice and a chance to not take the wrong road.

I don't live beyond my means. I enjoy luxury and I enjoy the privilege of it, when I can afford it, and I'm in the situation where it's been given to me, but I'm very conscious of what is wasteful.
