Disappointment is an endless wellspring of comedy inspiration.

Every actor is riddled with insecurity, of course. But weirdly, I don't really find that I'd be daunted with taking on roles or anything.

If you are a plumber, you can work on a shed, or you can work on a mansion. It's just scale.

Benedict (Cumberbatch, who is playing Sherlock) looks amazing. He's still got a Sherlockian silhouette, with a large overcoat, but in a classic cut. Watson dresses with an urban elegance, a touch of old school dashing, giving a feeling of both the military and medical profession. I suppose it's something they have in common as well. They're a bit metrosexual.

My idea of a good night out is staying in.

I like the idea of not everything happening between two human beings to be everyone's property.

I'm a big believer that life changes as much as you want it to.
